mu+-mu? colliders: possibilities and challenges  

SciTech Connect

The current status of the mu+-mu? collider concept is reviewed and discussed. In a reference scenario, a high-intensity pulsed proton accelerator (of K-factory class) produces large numbers of secondary pi's in a nuclear target, which produce muons by decay. The muons are collected and cooled (by "ionization cooling") to form high-intensity bunches that are accelerated to high-energy collisions. High-luminosity mu+-mu? and mu?-p colliders at TeV or higher energy scales may be possible. Challenges in implementing the scenario are described. Possible variations in muon production, accumulation, and collisions are discussed; further innovations and improvements are encouraged.

Evidence for the Decay Sigma+ -> p mu+ mu-  

E-Print Network (OSTI)

We report the first evidence for the decay Sigma+ -> p mu+ mu- from data taken by the HyperCP experiment(E871) at Fermilab. Based on three observed events, the branching ratio is B(Sigma+ -> p,mu+,mu-) = [8.6 +6.6,-5.4(stat) +/-5.5(syst)] x 10**-8. The narrow range of dimuon masses may indicate that the decay proceeds via a neutral intermediate state, Sigma+ -> p P0, P0 -> mu+ mu-, with a P0 mass of 214.3 +/- 0.5 MeV/c**2 and branching ratio B(Sigma+ -> p P0; P0 -> mu+ mu-) = [3.1 +2.4,-1.(stat) +/-1.5(syst)] x 10**-8.

K+ -> pi+ mu+ mu- in E865 at BNL  

E-Print Network (OSTI)

Preliminary values for the K+ -> pi+ mu+ mu- branching ratio and form factor are reported, based on 400 events, a factor of 2 more in total events and 100 times the present world sample of fully reconstructed events. The results are consistent with previous results on the pi+ e+ e- mode. However, the relatively large slope of the form factor in q^2, lambda = 0.182+/-0.01+/-0.007, required to fit the pi+ e+ e- data and to give consistency between the pi+ e+ e- and pi+ mu+ mu- branching ratios, is larger than expected in simple models of the decays. The K+ -> pi+ mu+ mu- branching ratio we find, (9.23 +/- 0.6 stat +/- 0.58 syst)x10^-8, is the most precise measurement of this mode and is approximately 3.2 sigma larger than the previous measurement. These pi+ l+ l- results are inconsistent with O(p^4) Chiral Perturbation Theory but compatible with O(p^6). Systematic studies for both modes are still in progress.

A muon that does not follow the traditional weak- force decay pattern into a lighter electron and two neutrinos, but converts wholly into an electron. WHAT WILL THIS TELL US ABOUT THE WORLD? * Observing Mu2e conversion would point the way to a unification of all the forces of nature controlling the interactions of matter. This unification of the four existing forces we observe today - gravity, the electromagnetic force, and the weak and strong forces - is considered Albert Einstein's dream of "grand unification. * Finding signs of this "grand unification" could explain how the universe evolved from being

The Catalysis of Nuclear Reactions by mu Mesons  

DOE Green Energy (OSTI)

In the course of a recent experiment involving the stopping of negative K mesons in a 10-inch liquid hydrogen bubble chamber, an interesting new reaction was observed to take place. The chamber is traversed by many more negative {mu} mesons than K mesons, so that in the last 75,000 photographs, approximately 2500 {mu}{sup -} decays at rest have been observed. In the same pictures, several hundred {pi}{sup -} mesons have been observed to disappear at rest, presumably by one of the ''Panofsky reactions''. For tracks longer than 10 cm, it is possible to distinguish a stopping {mu} meson from a stopping {pi} meson by comparing its curved path (in a field of 11,000 gauss) with that of a calculated template. In addition to the normal {pi}{sup -} and {mu}{sup -} stoppings, we have observed 15 cases in which what appears (from curvature measurement) to be a {mu}{sup -} meson comes to rest in the hydrogen, and then gives rise to a secondary negative particle of 1.7 cm range, which in turn decays by emitting an electron. (A 4.1-Mev {mu} meson from {pi} - {mu} decay has a range of 1.0 cm.) The energy spectrum of the electrons from these 15 secondary particles looks remarkably like that of the {mu} meson. There are four electrons in the energy range 50 to 55 Mev, and none higher; the other electrons have energies varying from 50 Mev to 13 Mev. The most convincing proof that the primary particle actually comes to rest, and does not--for example--have a large resonant cross section for scattering at a residual range of 1.7 cm, is the following: In five of the 15 special events, there is a large gap between the last bubble of the primary track and the first bubble of the secondary track. This gap is a real effect, and not merely a statistical fluctuation in the spacing of the bubbles, since in some cases the tracks form a letter X, and in another case the secondary track is parallel to the primary, but displaced transversely by about 1 mm at the end of the primary. These real gaps appear also (although perhaps less frequently) between some otherwise normal-looking {mu}{sup -} endings and the subsequent decay electron; they are thought to be the distance traveled by the small neutral mesic atom.

Antiproton low-energy collisions with Ps-atoms and true muonium atoms ($\\mu^+\\mu^-$)  

E-Print Network (OSTI)

Three-charge-particle collisions with participation of ultra-slow antiprotons ($\\bar{\\rm{p}}$) is the subject of this work. Specifically we compute the total cross sections and corresponding thermal rates of the following three-body reactions: $\\bar{\\rm p}+(e^+e^-) \\rightarrow \\bar{\\rm{H}} + e^-$ and $\\bar{\\rm p}+(\\mu^+\\mu^-) \\rightarrow \\bar{\\rm{H}}_{\\mu} + \\mu^-$, where $e^-(\\mu^-)$ is an electron (muon) and $e^+(\\mu^+)$ is a positron (antimuon) respectively, $\\bar{\\rm{H}}=(\\bar{\\rm p}e^+)$ is an antihydrogen atom and $\\bar{\\rm{H}}_{\\mu}=(\\bar{\\rm p}\\mu^+)$ is a muonic antihydrogen atom, i.e. a bound state of $\\bar{\\rm{p}}$ and $\\mu^+$. A set of two-coupled few-body Faddeev-Hahn-type (FH-type) equations is numerically solved in the framework of a modified close-coupling expansion approach.

Search for NMSSM Higgs bosons in the h ---> aa ---> mu mu mu mu, mu mu tau tau channels using p anti-p collisions at s**(1/2) = 1.96-TeV  

Science Conference Proceedings (OSTI)

We report on a first search for production of the lightest neutral CP-even Higgs boson (h) in the next-to-minimal supersymmetric standard model, where h decays to a pair of neutral pseudoscalar Higgs bosons (a), using 4.2 fb{sup -1} of data recorded with the D0 detector at Fermilab. The a bosons are required to either both decay to {mu}{sup +}{mu}{sup -} or one to {mu}{sup +}{mu}{sup -} and the other to {tau}{sup +}{tau}{sup -}. No significant signal is observed, and we set limits on its production as functions of M{sub a} and M{sub h}.

Relating B_S Mixing and B_S to mu+mu- with New Physics  

Science Conference Proceedings (OSTI)

We perform a study of the standard model fit to the mixing quantities {Delta}M{sub B{sub s}}, and {Delta}{Lambda}{sub B{sub s}}/{Delta}M{sub B{sub s}} in order to bound contributions of new physics (NP) to B{sub s} mixing. We then use this to explore the branching fraction of B{sub s} {yields} {mu}{sup +}{mu}{sup -} in certain models of NP. In most cases, this constrains NP amplitudes for B{sub s} {yields} {mu}{sup +}{mu}{sup -} to lie below the standard model component.

Search for B+ --> mu+ nu_mu With Inclusive Reconstruction at BaBar  

SciTech Connect

We search for the purely leptonic decay B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}} in the full BABAR dataset, having an integrated luminosity of approximately 426 fb{sup -1}. We adopt a fully inclusive approach, where the signal candidate is identified by the highest momentum lepton in the event and the companion B is inclusively reconstructed without trying to identify its decay products. We set a preliminary upper limit on the branching fraction of {Beta}(B{sup {+-}} {yields} {mu}{sup {+-}}{nu}{sub {mu}}) < 1.3 x 10{sup -6} at the 90% confidence level, using a Bayesian approach.

OM Code Requirements For MOVs -- OMN-1 and Appendix III  

SciTech Connect

The purpose or scope of the ASME OM Code is to establish the requirements for pre-service and in-service testing of nuclear power plant components to assess their operational readiness. For MOVs this includes those that perform a specific function in shutting down a reactor to the safe shutdown condition, maintaining the safe shutdown condition, and mitigating the consequences of an accident. This paper will present a brief history of industry and regulatory activities related to MOVs and the development of Code requirements to address weaknesses in earlier versions of the OM Code. The paper will discuss the MOV requirements contained in the 2009 version of ASME OM Code, specifically Mandatory Appendix III and OMN-1, Revision 1.

The M.U.5 Computer System  

E-Print Network (OSTI)

Describes the design of the MU5 research computer, the aim of which has been to produce a high performance machine whose structure is well suited to the needs of modern high level languages. It is hoped that a computing speed improvement of about 20 over the 2-3 mu S instruction rate of ATLAS will be obtained. In the ten years which have elapsed between the ATLAS and MU5 projects, the speed of logic gates and main storage has increased by a factor of 8:1, and this will result in a commensurate increase in system performance. In order to approach the 20:1 performance target, however, it will be necessary to adopt extensive parallel processing techniques, and to incorporate data buffering systems to compensate for the disparity between processor and storage speeds.

ATCA/muTCA for Physics  

Science Conference Proceedings (OSTI)

ATCA/{mu}TCA platforms are attractive because of the modern serial link architecture, high availability features and many packaging options. Less-demanding availability applications can be met economically by scaling back speed and redundancy. The ATCA specification was originally targeted for the Telecom industry but has gained recently a much wider user audience. The purpose of this paper is to report on present hardware and software R and D efforts where ATCA and {mu}TCA are planned, already being used or in development using selected examples for accelerator and detectors in the Physics community. It will present also the status of a proposal for physics extensions to ATCA/{mu}TCA specifications to promote inter-operability of laboratory and industry designs for physics.

Higgs boson decay to mu mubar gamma  

E-Print Network (OSTI)

The Higgs boson decay, H -> mu mubar gamma, is studied in the Standard Model at the tree and one-loop levels. It is shown that for Higgs boson masses above 110 GeV, the contribution to the radiative width from the one-loop level exceeds the contribution from the tree level, and for Higgs boson masses above 140 GeV, it even exceeds the contribution from the tree level decay H -> mu mubar. We also show that the contributions to the radiative decay width from the interference terms between the tree and one-loop diagrams are negligible.

Leptonic CP Phase in {nu}{sub {mu}}{yields}{nu}{sub {mu}} Oscillations  

Science Conference Proceedings (OSTI)

In the case of large 1-3 mixing angle as sin{sup 2} 2{theta}{sub 13}{>=}0.03, we investigate the possibility for measuring the leptonic CP phase by using only {nu}{sub {mu}}{yields}{nu}{sub {mu}} oscillations independently of {nu}{sub {mu}}{yields}{nu}{sub e} oscillations. As the result, we find that the CP phase can be measured best around the energy E = 0.43 GeV and the baseline length L = 5000 km without depending on the uncertainties of other parameters too much. In this region, the CP phase effect remains even after averaging over neutrino energy.

Lepton flavour violating Higgs Boson decays, tau --> mu gamma and B(s) --> mu+mu- in the constrained MSSM+NR with large tan beta  

E-Print Network (OSTI)

Realistic predictions are made for the rates of lepton flavour violating Higgs boson decays, tau --> mu gamma, mu --> e gamma, Bs --> mu+mu-, Bs --> tau mu and tau --> 3mu, via a top-down analysis of the Minimal Supersymmetric Standard Model(MSSM) constrained by SU(5) unification with right-handed Neutrinos and large tan beta. The third family neutrino Yukawa coupling is chosen to be of order 1, in this way our model bares a significant resemblance to supersymmetric SO(10). In this framework the large PMNS mixings result in potentially large lepton flavour violation. Our analysis predicts tau --> mu gamma and mu --> e gamma rates in the region (10^{-8}-10^{-6}) and (10^{-15}-10^{-14}) respectively. We also show that the rates for lepton flavour violating Higgs decays can be as large as 10^{-7}. The non-decoupling nature of H --> tau mu is observed which leads to its decay rate becoming comparable to that for tau --> mu gamma for large values of m_0 and M_1/2. We also find that the present bound on Bs --> mu+mu- is an important constraint on the rate of lepton flavour violating Higgs decays. The recently measured Bs-Bsbar mixing parameter Delta Ms is also investigated.

R Symmetry and the Mu Problem  

E-Print Network (OSTI)

A natural origin for the mu and B parameters of weak scale supersymmetric theories is proposed, applicable to any supersymmetry breaking messenger scale between the weak and Planck scales. Although quite general, it requires supersymmetric interactions to respect an R symmetry with definite quantum numbers, and it requires some new scale of symmetry breaking. The required R symmetry distinguishes the Higgs boson from the sneutrino, preserves baryon number in operators of dimension four and five, and contains R parity so that the lightest superpartner is stable. This origin for mu works for a variety of mediation mechanisms, including gauge mediation, gaugino mediation, and boundary condition breaking of supersymmetry. In any of these mediation schemes, our mechanism leads to a real B parameter, and the supersymmetric CP problem is solved. This R symmetry may naturally arise from supersymmetric theories in higher dimensions.

The N=1 algebra W_\\infty[\\mu] and its truncations  

E-Print Network (OSTI)

We construct and classify the most general classical and quantum N=1 W_\\infty-algebras generated by the same spins as the singlet algebra of M fermions and M bosons in the vector representation of O(M) in the large M limit. This type of algebras appears in a recent N=1 version of the minimal model holography. Our analysis shows that there is a one parameter family W_\\infty[\\mu] of such algebras at every given central charge. We identify various truncations of W_\\infty[\\mu] with, on the one hand, (orbifolds of) the Drinfel'd-Sokolov reductions of the Lie superalgebras B(n,n), B(n-1,n), D(n,n) and D(n+1,n), and, on the other hand, (orbifolds of) three N=1 cosets. A closer inspection reveals that these cosets can be realized as a Drinfel'd-Sokolov reduction of B(n,n), D(n,n) and D(n+1,n). We then discuss the implications of our findings for the quantum version of the N=1 minimal model holography.

Partition Function of the Reissner-Nordstr\\"om Black Hole  

E-Print Network (OSTI)

We consider a microscopic model of a stretched horizon of the Reissner-Nordstr\\"om black hole. In our model the stretched horizon consists of discrete constituents. Using our model we obtain an explicit, analytic expression for the partition function of the hole. Our partition function implies, among other things, the Hawking effect, and provides it with a microscopic explanation as a phase transition taking place at the stretched horizon. The partition function also implies the Bekenstein-Hawking entropy law. The model and its consequences are similar to those obtained previously for the Schwarzschild black hole.

Branching ratio for a light Higgs boson to decay into. mu. /sup +/. mu. /sup -/ pairs  

SciTech Connect

We evaluate the effects of final-state interactions on the decay of a light Higgs boson to two pions. Although the formalism is completely general and can be applied to any strong-interaction decay mode of the Higgs boson, we are particularly interested in the regime where the Higgs-boson mass m/sub h/ satisfies the constraint 2m/sub ..pi../mu../sup +/..mu../sup -/ and two pions. Final-state interactions tend to enhance the two-pion mode and thus suppress the branching ratio to two muons. Since the two-muon mode is the cleanest signature for identifying the Higgs boson, it is important to obtain a good determination of this branching ratio. We find B(h..--> mu../sup +/..mu../sup -/) approx. =0/sup -2/--10/sup -1/.

CP violating phases in mu-e conversion  

E-Print Network (OSTI)

Experiments are planned to improve the sensitivity of mu-e conversion from the current ~ 10^{-12} to 10^{-16} - 10^{-18}. If the muon (bound to the nucleus) could be polarised, a spin asymmetry of the final state electron is sensitive to CP violating phases on lepton flavour violating operators. This is similar to extracting phases from asymmetries in the final state spin and phase space distributions of mu to 3e and mu to e gamma.

SPITZER 24 {mu}m IMAGES OF PLANETARY NEBULAE  

SciTech Connect

Spitzer MIPS 24 {mu}m images were obtained for 36 Galactic planetary nebulae (PNe) whose central stars are hot white dwarfs (WDs) or pre-WDs with effective temperatures of {approx}100,000 K or higher. Diffuse 24 {mu}m emission is detected in 28 of these PNe. The eight nondetections are angularly large PNe with very low H{alpha} surface brightnesses. We find three types of correspondence between the 24 {mu}m emission and H{alpha} line emission of these PNe: six show 24 {mu}m emission more extended than H{alpha} emission, nine have a similar extent at 24 {mu}m and H{alpha}, and 13 show diffuse 24 {mu}m emission near the center of the H{alpha} shell. The sizes and surface brightnesses of these three groups of PNe and the nondetections suggest an evolutionary sequence, with the youngest ones being brightest and the most evolved ones undetected. The 24 {mu}m band emission from these PNe is attributed to [O IV] 25.9 {mu}m and [Ne V] 24.3 {mu}m line emission and dust continuum emission, but the relative contributions of these three components depend on the temperature of the central star and the distribution of gas and dust in the nebula.

Length monitor for 1 mm SLC bunches  

SciTech Connect

A non-intercepting RF bunch length monitor for {sigma}{sub z} = 0.5 to 2.0 mm long electron and positron bunches in the Stanford Linear Collider (SLC) has been built with a design similar to a previous device for longer bunches. For this device, fields from the beam pass through a ceramic gap, enter receiving cavities, are the measured with power detectors, and finally are recorded by the SLC control computer. The designs of the receiving cavities (25 and 36 GHz) are described as well as the choice of the RF power distribution and measuring systems. Beam measurements have been taken as a function of bunch compressor RF voltage, bunch intensity, and beam position. Long term bunch length measurements were recorded during SLC colliding beam operation indicating that the bunch length is constant to about 3%. Thus, 1 mm length monitors operating at 25 and 36 GHz have successfully monitored long term bunch length changes at the few percent level in the SLC.

Viewing the Evolution of Massive Star Formation through FIR/Sub-mm/mm Eyes  

E-Print Network (OSTI)

In this paper, we present an overview of our method of constructing a family of models for the far-infrared, sub-millimeter, and millimeter (FIR/sub-mm/mm) line emission of molecular and atomic gas surrounding massive star formation in starburst galaxies. We show the results of a case study, an expanding supershell centered around a massive star cluster with a particular set of input parameters and its application to nearby starburst galaxy M 82. This set of models can be used not only to interpret the observations of FIR/sub-mm/mm line emission from molecular and atomic gas, but also to investigate the physical environment and the initial cloud conditions in massive star forming regions as well as the ages of the starbursts through simulations for a wide range of input parameters. Finally, we discuss limitations of our models, and outline future work.

Lepton flavour violating Higgs and tau to mu gamma  

E-Print Network (OSTI)

We update phenomenological constraints on a Two Higgs Doublet Model with lepton flavour non-conserving Yukawa couplings. We review that $\\tan \\beta$ is ambiguous in such "Type III" models, and define it from the $\\tau$ Yukawa coupling. The neutral scalars $\\phi$ could be searched for at hadron colliders in $ \\phi \\to \\tau \\bar{\\mu}$, and are constrained by the rare decay $\\tau \\to \\mu \\gamma$. The Feynman diagrams for the collider process, with Higgs production via gluon fusion, are similar to the two-loop "Barr-Zee" diagrams which contribute to $\\tau \\to \\mu \\gamma$. Some "tuning" is required to obtain a collider cross-section of order the Standard Model expectation for $\\sigma (gg \\to h_{SM} \\to \\tau^+ \\tau^-)$, while agreeing with the current bound from $\\tau \\to \\mu \\gamma$.

This work presents a search for the pair production of doubly-charged Higgs Bosons in the process p{bar p} {yields} H{sup ++}H{sup --} {yields} {mu}{sup +}{mu}{sup +}{mu}{sup -}{mu}{sup -} using inclusive dimuon events. These data correspond to an integrated luminosity of about 113 pb 1 and were recorded by the D0 experiment between August 2002 and June 2003. In the absence of a signal, 95% confidence level mass limits of M(H{sub L}{sup {+-}{+-}}) > 118.6 GeV/c{sup 2} and M(H{sub R}{sup {+-}{+-}}) > 98.1 GeV/c{sup 2} are set for left-handed and right-handed doubly-charged Higgs boson, assuming 100% branching into muons and hypercharge |Y| = 2 and Yukawa coupling h{sub {mu}{mu}} > 10{sup -7}. This is the first search for doubly-charged Higgs bosons at hadron colliders. It significantly extends the previous mass limit of 100.5 GeV/c{sup 2} for a left-handed doubly-charged Higgs boson measured in the muon final states by the OPAL collaboration.

A Hydrodynamical Approach to CMB mu-distortions  

E-Print Network (OSTI)

Spectral distortion of the cosmic microwave background provides a unique opportunity to probe primordial perturbations on very small scales by performing large-scale measurements. We discuss in a systematic and pedagogic way all the relevant physical phenomena involved in the production and evolution of the mu-type spectral distortion. Our main results agree with previous estimates (in particular we show that a recently found factor of 3/4 arises from relativistic corrections to the wave energy). We also discuss several subleading corrections such as adiabatic cooling and the effects of bulk viscosity, baryon loading and photon heat conduction. Finally we calculate the transfer function for mu-distortions between the end of the mu-era and now.

Scalar meson mediated nuclear mu-e conversion  

E-Print Network (OSTI)

We study the nuclear mu-e conversion in the general framework of the effective Lagrangian approach without referring to any specific realization of the physics beyond the standard model (SM) responsible for lepton flavor violation (LFV). We analyze the role of scalar meson exchange between the lepton and nucleon currents and show its relevance for the coherent channel of mu-e conversion. We show that this mechanism introduces modifications in the predicted mu-e conversion rates in comparison with the conventional direct nucleon mechanism, based on the contact type interactions of the nucleon currents with the LFV leptonic current. We derive from the experimental data lower limits on the mass scales of the generic LFV lepton-quark contact terms and demonstrate that they are more stringent than the similar limits existing in the literature.

Laser enhancement of resonance (dt. mu. ,d2e) and (dd. mu. ,d2e) (molecular) formation  

SciTech Connect

The enhancement of resonance molecular formation rates of (dt..mu..,d2e) and (dd..mu..,d2e) by strong laser irradiation have been studied. The formation rates decrease until the laser intensity reaches the order of 10/sup 8/ to 10/sup 9/ W/cm/sup 2/, and they increase substantially for the intensity range of 10/sup 10/ W/cm/sup 2/ to 10/sup 11/ W/cm/sup 2/. The (dt..mu..,d2e) formation rate using the angular frequency laser such as 11.4 x 10/sup 13/ rad/sec becomes 4 x 10/sup 10/ l/sec for the laser intensity of 3 x 10/sup 10/ W/cm/sup 2/. Further increase of laser intensity reduces the formation rate due to the mismatch of the resonance condition. The formation rate is very sensitive to the frequency of the laser and the formation rate of (dd..mu..,d2e) becomes comparable with one of (dt..mu..,d2e) for the cases of w = 22.8 x 10/sup 13/ rad/sec. For the case of dt initial molecule, there is the possibility of enhancing the formation rate by exciting the vibrational motion by laser field.

Airbreathing Laser Propulsion Experiments with 1 {mu}m Terawatt Pharos IIILaser: Part 2  

Science Conference Proceedings (OSTI)

This basic research study examines the physics of airbreathing laser propulsion at the extreme flux range of 1-2x10{sup 11} W/cm{sup 2}--within the air breakdown threshold for l {mu}m radiation--using the terawatt Pharos III neodymium-glass pulsed laser. Six different experimental setups were employed using a 34 mm line focus with 66 {mu}m focal waist, positioned near the flat impulse surface. The 2nd Campaign investigated impulse generation with the laser beam focused at grazing incidence across near horizontal target surfaces, with pulse energies ranging from 55 to 186 J, and pulse-widths of 2 to 30 ns FWHM. Laser generated impulse was measured with a horizontal Plexiglas registered ballistic pendulum equipped with either a steel target insert or 0.5 Tesla permanent magnet (NEIT-40), to quantify changes in the momentum coupling coefficient (C{sub M}). Part 2 of this 2-part paper covers Campaign no. 2 results including C{sub M} performance data, and long exposure color photos of LP plasma phenomena.

Interpreting the New Brookhaven g_mu - 2 Result  

E-Print Network (OSTI)

The latest g_mu - 2 measurement by Brookhaven confirms the earlier measurement with twice the precision. However, interpretation of the result requires specific assumptions regarding the errors in the hadronic light by light (LbL) correction and in the hadronic vacuum polarization correction. Under the assumption that the analysis on LbL correction of Knecht and Nyffeler and the revised analysis of Hayakawa and Kinoshita are valid the new BNL result implies a deviation between experiment and the standard model of 1.6 sigma -2.6 sigma depending on the estimate of the hadronic vacuum polarization correction. We revisit the g_mu - 2 constraint for mSUGRA and its implications for the direct detection of sparticles at colliders and for the search for supersymmetric dark matter in view of the new evaluation.

The Bolocam Galactic Plane Survey IV: 1.1 and 0.35 mm Dust Continuum Emission in the Galactic Center Region  

E-Print Network (OSTI)

The Bolocam Galactic Plane Survey (BGPS) data for a six square degree region of the Galactic plane containing the Galactic center is analyzed and compared to infrared and radio continuum data. The BGPS 1.1 mm emission consists of clumps interconnected by a network of fainter filaments surrounding cavities, a few of which are filled with diffuse near-IR emission indicating the presence of warm dust or with radio continuum characteristic of HII regions or supernova remnants. New 350 {\\mu}m images of the environments of the two brightest regions, Sgr A and B, are presented. Sgr B2 is the brightest mm-emitting clump in the Central Molecular Zone and may be forming the closest analog to a super star cluster in the Galaxy. The Central Molecular Zone (CMZ) contains the highest concentration of mm and sub-mm emitting dense clumps in the Galaxy. Most 1.1 mm features at positive longitudes are seen in silhouette against the 3.6 to 24 {\\mu}m background observed by the Spitzer Space Telescope. However, only a few clumps ...

SUBMILLIMETER POLARIZATION OF GALACTIC CLOUDS: A COMPARISON OF 350 {mu}m AND 850 {mu}m DATA  

Science Conference Proceedings (OSTI)

The Hertz and SCUBA polarimeters, working at 350 {mu}m and 850 {mu}m, respectively, have measured the polarized emission in scores of Galactic clouds. Of the clouds in each data set, 17 were mapped by both instruments with good polarization signal-to-noise ratios. We present maps of each of these 17 clouds comparing the dual-wavelength polarization amplitudes and position angles at the same spatial locations. In total number of clouds compared, this is a four-fold increase over previous work. Across the entire data set real position angle differences are seen between wavelengths. While the distribution of {phi}(850)-{phi}(350) is centered near zero (near-equal angles), 64% of data points with high polarization signal-to-noise (P {>=} 3{sigma}{sub p}) have |{phi}(850)-{phi}(350)| > 10 Degree-Sign . Of those data with small changes in position angle ({<=}10 Degree-Sign ) the median ratio of the polarization amplitudes is P(850)/P(350) = 1.7 {+-} 0.6. This value is consistent with previous work performed on smaller samples and models that require mixtures of different grain properties and polarization efficiencies. Along with the polarization data we have also compiled the intensity data at both wavelengths; we find a trend of decreasing polarization with increasing 850-to-350 {mu}m intensity ratio. All the polarization and intensity data presented here (1699 points in total) are available in electronic format.

Study of ttH (H -> mu mu) in the three lepton channel at sqrt(s) = 14 TeV; A Snowmass white paper  

E-Print Network (OSTI)

The H -> mu mu signature provides excellent mass resolution for Higgs bosons, and is therefore an important Higgs boson decay channel despite the small dimuon branching ratio. We present an optimization of selection criteria in a search for trilepton ttH (H -> mu mu) events, in which the top quark pair decays semi-leptonically, at a simulated High Luminosity LHC (HL-LHC) running at 14 TeV. The study is performed with 3000 fb^(-1) of simulated data with an average pileup of = 140. In this ultimate HL-LHC data set, we find that ttH (H -> mu mu) will be a very difficult signature to observe due to the very small expected signal.

Elucidating the organic-OMS interface and its implications for heterogeneous catalysts  

E-Print Network (OSTI)

Organic – ordered mesoporous silica (OMS) hybrid materials have attracted great interest due to their potential applications for gas separations, and heterogeneous catalysis. Amine-functionalized OMS materials are active in a variety of base-catalyzed reactions. The key to successfully achieving the desired reactivity is the ability to rationally tether the targeted organic functionality onto the OMS surface. Understanding the organic-inorganic interface is crucial for rational design of heterogeneous catalysts, because the local structure and molecule dynamics are paramount in determining the reactivity of the organic groups attached to the OMS surface. This dissertation focuses on three goals that will lead to a description of the organic-OMS interface and designing hybrid catalysts: 1) Determining the dynamics of organic groups attached to the OMS surface, 2) Catalytic testing to understand how the local structure and dynamics of the organic moiety influence the catalytic properties of organic-OMS catalysts, 3) Designing more active hybrid catalysts by introducing higher loadings of organic group using dendrimer structures. Solid-state NMR is uniquely suited for quantifying dynamics in the milli- to nano-second time scale. Deuterium (2H) NMR is a powerful tool to obtain detailed information about the dynamics or organic molecules. In this study, several simple functional groups isotopically labeled with deuterium have been attached to MCM-41 and SBA-15. The spectra display different molecular motions for different organic moieties. The results have indicated that the interactions between the functional groups and silanol groups on the surface influence the mobility of the organic fragments. Also, the porosity of the solid supports effects dynamics via confinement. The catalytic properties of simple amine groups attached to MCM-41, containing primary, secondary, and tertiary amines have been compared in the Nitroaldol (Henry) reaction. The effects of amine identity, structure, loading, presence of surface silanols, and the substrate topology on the catalytic properties have been investigated. The dramatic decrease of the activity of amine-functionalized MCM-41 by capping the residual silanol groups with hexamethyldisilazane was ascribed to the decrease of the interactions of hydrogen bonding between the amine functional groups and surface silanols. The result was consistent with the changes of the molecular motions shown by 2H NMR measurements. Fabricating OMS hybrid materials with high densities of organic functional groups leads to challenges in realizing uniform, catalytically active sites. Our group has immobilized melamine-based dendrimers on the surfaces of amine-functionalized SBA-15 materials by iterative synthesis procedures. The current studies in this dissertation mainly describe the catalytic properties of these dendrimers on SBA-15 and MCM-41 in the Nitroaldol (Henry) reaction, the transesterification reaction of triglycerides and methanol to synthesize methyl esters, and the cross aldol reaction between acetone and 5-hydroxymethylfurfural. The results indicate that the OMS-dendron materials have potential as solid base catalysts for a range of reactions.

Potential Operation and Maintenance (O&M) Savings in the John Sealy North Building at UTMB  

E-Print Network (OSTI)

The LoanSTAR Monitoring and Analysis Group, Energy Systems Laboratory at Texas A&M University, was requested by University of Texas Medical Branch at Galveston to investigate O&M measures in their five LoanSTAR program buildings. This report describes the suggested O&Ms in John Sealy North Building, a surgical building of 54,494 ft2,which currently spends $502,100 per year on electricity, steam and chilled water. The suggested O&Ms include optimizing the outside air treatment cold deck reset schedule, the cold deck reset schedule and the hot deck reset schedule. These optimized HVAC operation schedules were determined using an analysis involving a simplified HVAC model, which was calibrated against daily data measured by the LoanSTAR program. It is estimated that annual savings of $67,000, or 13% of the annual costs, can be realized using the optimized operation schedules which can be implemented without additional costs. Our analysis indicates that the room comfort levels will not be degraded by these measures.

Elaborating on a previous letter [1], we use a new approach to compute energy levels of a nonrelativistic bound-state of two constituents, with masses m and M, by systematic expansions--one in powers of m/M and another in powers of (1-m/M). Technical aspects of the calculations are described in detail. Theoretical predictions are given for {Omicron}({alpha}(Z{alpha}){sup 5}) radiative recoil and {Omicron}((Z{alpha}){sup 6}) pure recoil corrections to the average energy shift and hyperfine splitting relevant for hydrogen, muonic hydrogen, and muonium.

Distillation of Strangelets for low initial mu/T  

E-Print Network (OSTI)

We calculate the evolution of quark-gluon-plasma droplets during the hadronization in a thermodynamical model. It is speculated that cooling as well as strangeness enrichment allow for the formation of strangelets even at very high initial entropy per baryon $S/A^{\\rm init}\\approx 500$ and low initial baryon numbers of $A_{\\rm B}^{\\rm init}\\approx 30$. It is shown that the droplet with vanishing initial chemical potential of strange quarks and a very moderate chemical potential of up/down quarks immediately charges up with strangeness. Baryon densities of $\\approx 2\\rho_0$ and strange chemical potentials of $\\mu_s>350$~MeV are reached if strangelets are stable. The importance of net--baryon and net--strangeness fluctuations for the possible strangelet formation at RHIC and LHC is emphasized.

MuCap: Muon capture on the proton to determine the pseudoscalar coupling, gp  

Science Conference Proceedings (OSTI)

The MuCap collaboration has measured the capture rate of the muon on the proton and reported its first value for the weak pseudoscalar coupling: gp 7.3{+-}1.1. To achieve 5% uncertainty on gp, many hardware upgrades were implemented for the subsequent 2006-2007 running periods. These improvements are described and the outlook for MuCap and the followup experiment, MuSun, is discussed.

An update for the MuCool test area  

DOE Green Energy (OSTI)

Construction of a new facility known as the MuCool Test Area (MTA) has been completed at Fermi National Accelerator Laboratory. This facility supports research in new accelerator technologies for future endeavors such as a Neutrino Factory or Muon Collider. During the summer of 2004, an initial set of tests was completed for the filling of a convection-style liquid hydrogen absorber designed by KEK. The absorber contained 6.2 liquid liters of hydrogen and was tested for a range of heating conditions to quantify the absorber's heat exchanger performance. Future work at Fermilab includes the design, construction, and installation of a forced-flow absorber to be used with other components built to investigate the properties of a muon ionization cooling channel. A Tevatron-style refrigerator/compressor building is to be operational by spring of 2006 in support of the absorber tests and also to provide 5-K helium and liquid nitrogen to a 5-T solenoid magnet, an active element of the future test apparatus. The refrigerator will be configured in such a manner as to meet the 5 K and 14-20-K helium needs of the MTA. This paper reviews the challenges and successes of the past KEK absorber tests as well as looks into the future cryogenic capabilities and intentions of the site.

Cryogenics for the MuCool Test Area (MTA)  

DOE Green Energy (OSTI)

MuCool Test Area (MTA) is a complex of buildings at Fermi National Accelerator Laboratory, which are dedicated to operate components of a cooling cell to be used for Muon Collider and Neutrino Factory R&D. The long-term goal of this facility is to test ionization cooling principles by operating a 25-liter liquid hydrogen (LH{sub 2}) absorber embedded in a 5 Tesla superconducting solenoid magnet. The MTA solenoid magnet will be used with RF cavities exposed to a high intensity beam. Cryogens used at the MTA include LHe, LN{sub 2} and LH{sub 2}. The latter dictates stringent system design for hazardous locations. The cryogenic plant is a modified Tevatron refrigerator based on the Claude cycle. The implementation of an in-house refrigerator system and two 300 kilowatt screw compressors is under development. The helium refrigeration capacity is 500 W at 14 K. In addition the MTA solenoid magnet will be batch-filled with LHe every 2 days using the same cryo-plant. This paper reviews cryogenic systems used to support the Muon Collider and Neutrino Factory R&D programs and emphasizes the feasibility of handling cryogenic equipment at MTA in a safe manner.

Precision monitoring of relative beam intensity for Mu2e  

SciTech Connect

For future experiments at the intensity frontier, precise and accurate knowledge of beam time structure will be critical to understanding backgrounds. The proposed Mu2e experiment will utilize {approx}200 ns (FW) bunches of 3 x 10{sup 7} protons at 8 GeV with a bunch-to-bunch period of 1695 ns. The out-of-bunch beam must be suppressed by a factor of 10{sup -10} relative to in-bunch beam and continuously monitored. I propose a Cerenkov-based particle telescope to measure secondary production from beam interactions in a several tens of microns thick foil. Correlating timing information with beam passage will allow the determination of relative beam intensity to arbitrary precision given a sufficiently long integration time. The goal is to verify out-of-bunch extinction to the level 10{sup -6} in the span of several seconds. This will allow near real-time monitoring of the initial extinction of the beam resonantly extracted from Fermilabs Debuncher before a system of AC dipoles and collimators, which will provide the final extinction. The effect on beam emittance is minimal, allowing the necessary continuous measurement. I will present the detector design and some concerns about bunch growth during the resonant extraction.

The Behaviour Of Zirconium Alloys In Santowax OM Organic Coolant At High Temperature  

DOE Green Energy (OSTI)

Zirconium alloys have been exposed to Santowax OM at temperatures of 320 to 400 deg C for times as long as 5000 hours. Short-term experiments (less than 2 weeks) were done in stainless-steel bombs and small out-of-pile loops. The X-7 organic loop in the NRX reactor was used to study long-term oxidation and hydriding both in-flux and out-of-flux. The results obtained lead to several tentative conclusions. 1. Aluminum cladding serves as an effective hydrogen barrier. 2. Considerable protection against hydriding is given by zirconium oxide, provided impurities in the organic are carefully controlled. Hydriding is greatly enhanced by the presence of chlorine in the coolant. 4. Hydriding is somewhat enhanced by neutron irradiation. Of considerable significance is the fact that a Zircaloy-4 in-reactor test section of the X-7 loop was exposed to Santowax OM at 320 to 400 deg C for more than 5000 hours without excessive hydriding.

Enhanced mu-e conversion in nuclei in the inverse seesaw model  

E-Print Network (OSTI)

We investigate nuclear mu-e conversion in the framework of an effective Lagrangian arising from the inverse seesaw model of neutrino masses. We consider lepton flavour violation interactions that arise from short range (non-photonic) as well as long range (photonic) contributions. Upper bounds for the LFV parameters characterizing mu-e conversion are derived in the inverse seesaw model Lagrangian using the available limits on the mu-e conversion branching ratio, as well as the expected sensitivities of upcoming experiments. We comment on the relative importance of these two types of contributions and their relationship with the measured solar neutrino mixing angle theta_12 and the dependence on theta_13. Finally we show how the LFV mu-e conversion and the mu -> e gamma rates are strongly correlated in this model.

SPITZER 24 {mu}m SURVEY FOR DUST DISKS AROUND HOT WHITE DWARFS  

Science Conference Proceedings (OSTI)

Two types of dust disks around white dwarfs (WDs) have been reported: small dust disks around cool metal-rich WDs consisting of tidally disrupted asteroids and a large dust disk around the hot central WD of the Helix planetary nebula (PN) possibly produced by collisions among Kuiper-Belt-like objects. To search for more dust disks of the latter type, we have conducted a Spitzer MIPS 24 {mu}m survey of 71 hot WDs or pre-WDs, among which 35 are central stars of PNe (CSPNs). Nine of these evolved stars are detected and their 24 {mu}m flux densities are at least two orders of magnitude higher than their expected photospheric emission. Considering the bias against the detection of distant objects, the 24 {mu}m detection rate for the sample is {approx}>15%. It is striking that seven, or {approx}20%, of the WD and pre-WDs in known PNe exhibit 24 {mu}m excesses, while two, or 5%-6%, of the WDs not in PNe show 24 {mu}m excesses and they have the lowest 24 {mu}m flux densities. We have obtained follow-up Spitzer Infrared Spectrograph spectra for five objects. Four show clear continuum emission at 24 {mu}m, and one is overwhelmed by a bright neighboring star but still shows a hint of continuum emission. In the cases of WD 0950+139 and CSPN K 1-22, a late-type companion is present, making it difficult to determine whether the excess 24 {mu}m emission is associated with the WD or its red companion. High-resolution images in the mid-infrared are needed to establish unambiguously the stars responsible for the 24 {mu}m excesses.

DISCOVERY AND ANALYSIS OF 21 {mu}m FEATURE SOURCES IN THE MAGELLANIC CLOUDS  

Science Conference Proceedings (OSTI)

Spitzer Space Telescope mid-infrared spectroscopy has been obtained for 15 carbon-rich protoplanetary nebulae (PPNe) in the Large Magellanic Cloud (LMC) and for two other such stars in the Small Magellanic Cloud (SMC). Of these 17 PPNe, the unidentified 21 {mu}m feature is strong in 7 spectra, weak in 2 spectra, and very weak or questionable in 4 spectra. Two of the four spectra without the 21 {mu}m feature have a very strong feature near 11 {mu}m, similar to a feature observed in some carbon-rich planetary nebulae (PNe) in the LMC. We attribute this feature to unusual SiC dust, although the feature-to-continuum ratio is much larger than for SiC features in Galactic or Magellanic Cloud carbon star spectra. The remaining two objects show typical carbon-rich PPNe spectra with no 21 {mu}m features. One of the LMC objects that lacks the 21 {mu}m feature and one SMC object with a questionable 21 {mu}m detection may have mixed dust chemistries based upon their spectral similarity to Galactic [WC] PNe. The 13 objects that either definitely or may show the 21 {mu}m feature have distinct dust shell properties compared to the Galactic 21 {mu}m objects-the 21 {mu}m features are weaker, the estimated dust temperatures are significantly higher, the unidentified infrared (UIR) bands are stronger, and the UIRs show more structure. Four of the 21 {mu}m objects appear to show normal SiC emission features in their spectra. Many of the PPNe show strong 30 {mu}m features, although this feature carries less of the total mid-infrared emission than is normally the case for the Galactic 21 {mu}m PPNe. The LMC objects are in the LMC halo rather than in the LMC bar. The estimated luminosities of these PPNe vary from 4700 to 12,500 L{sub sun}.

After making the usual model assumptions, the shape of the dsigma/dQ$sup 2$ distribution and the energy dependence and magnitude of the cross section were fit in order to determine the shape of the form factors for the reaction $nu$d $Yields$ $mu$$sup -$pp. It is noted that one can also test the CVC hypothesis. The cross section is shown as a function of neutrino energy for the $nu$n $Yields$ $mu$$sup -$p reaction. Also shown is the Q$sup 2$ dependence of the $nu$n $Yields$ $mu$$sup -$p events. (JFP)

A search for the rare decay. mu. /sup +/. -->. e/sup +/. gamma gamma  

SciTech Connect

An experimental search for the lepton-family number nonconserving decay, ..mu../sup +/ ..-->.. e/sup +/..gamma gamma.., has been conducted at the Clinton P. Anderson Meson Physics Facility (LAMPF) using the Crystal Box detector. The detector consists of a modular NaI(Tl) calorimeter, scintillator hodoscope, and a high-resolution, cylindrical drift chamber. It provides a large solid-angle for detecting three-body decays and has good resolutions in the time, position, and energy measurements to eliminate unwanted backgrounds. No evidence for ..mu../sup +/ ..-->.. e/sup +/..gamma gamma.. is found, giving an upper limit for the branching ratio of GAMMA(..mu.. ..-->.. e..gamma gamma..)/GAMMA(..mu.. ..-->.. e nu anti nu) less than or equal to 7.2 x 10/sup -11/ (90% C.L.). This result is an improvement of more than two orders of magnitude in the existing limit. 109 refs., 39 figs.

Lepton flavor violating Higgs bosons and {tau}{yields}{mu}{gamma}  

SciTech Connect

We update phenomenological constraints on a two Higgs doublet model with lepton flavor nonconserving Yukawa couplings. We review that tan{beta} is ambiguous in such 'type III' models, and define it from the {tau} Yukawa coupling. The neutral scalars {phi} could be searched for at hadron colliders in {phi}{yields}{tau}{mu} and are constrained by the rare decay {tau}{yields}{mu}{gamma}. The Feynman diagrams for the collider process, with Higgs production via gluon fusion, are similar to the two-loop ''Barr-Zee'' diagrams, which contribute to {tau}{yields}{mu}{gamma}. Some ''tuning'' is required to obtain a collider cross section of order the standard model expectation for {sigma}(gg{yields}h{sub SM{yields}{tau}}{sup +{tau}-}), while agreeing with the current bound from {tau}{yields}{mu}{gamma}.

Proposal to search for mu- N -> e- N with a single event sensitivity below 10 -16  

SciTech Connect

We propose a new experiment, Mu2e, to search for charged lepton flavor violation with unprecedented sensitivity. We will measure the ratio of the coherent neutrinoless conversion in the field of a nucleus of a negatively charged muon into an electron to the muon capture process: R{sub {mu}e} = {mu}{sup -} + A(Z,N) {yields} e{sup -} + A(Z,N)/{mu}{sup -} + A(Z,N) {yields} {nu}{sub {mu}} + A(Z-1, N), with a sensitivity R{sub {mu}e} {le} 6 x 10{sup -17} at 90% CL. This is almost a four order-of-magnitude improvement over the existing limit. The observation of such a process would be unambiguous evidence of physics beyond the Standard Model. Since the discovery of the muon in 1936, physicists have attempted to answer I.I. Rabi's famous question: 'Who ordered that?' Why is there a muon? What role does it play in the larger questions of why there are three families and flavors of quarks, leptons, and neutrinos? We know quarks mix through a mechanism described by the Cabbibo-Kobayashi-Maskawa matrix, which has been studied for forty years. Neutrino mixing has been observed in the last decade, but mixing among the family of charged leptons has never been seen. The current limits are of order 10{sup -11} - 10{sup -13} so the process is rare indeed. Why is such an experiment important and timely? A major motivation for experiments at the Large Hadron Collider (LHC) is the possible observation of supersymmetric particles in the TeV mass range. Many of these supersymmetric models predict a {mu}-e conversion signal at R{sub {mu}e} {approx} 10{sup -15}. We propose to search for {mu}-e conversion at a sensitivity that exceeds this by more than an order of magnitude. The LHC may not be able to conclusively distinguish among supersymmetric models, so Mu2e will provide invaluable information should the LHC observe a signal. In the case where the LHC finds no evidence of supersymmetry, or other beyond-the-standard-model physics, Mu2e will probe for new physics at mass scales up to 10{sup 4} TeV, far beyond the reach of any planned accelerator.

Warm Spitzer Occultation Photometry of WASP-26b at 3.6{\\mu}m and 4.5{\\mu}m  

E-Print Network (OSTI)

We present new warm Spitzer occultation photometry of WASP-26 at 3.6{\\mu}m and 4.5{\\mu}m along with new transit photometry taken in the g,r and i bands. We report the first detection of the occultation of WASP-26b, with occultation depths at 3.6{\\mu}m and 4.5{\\mu}m of 0.00126 +/- 0.00013 and 0.00149 +/- 0.00016 corresponding to brightness temperatures of 1825+/-80K and 1725+/-89K, respectively. We find that the eccentricity of the orbit is consistent with a circular orbit at the 1{\\sigma} level with a 3{\\sigma} upper limit of e < 0.04. According to the activity-inversion relation of Knutson et al. (2010), WASP-26b is predicted to host a thermal inversion. The brightness temperatures deduced from the eclipse depths are consistent with an isothermal atmosphere, although it is within the uncertainties that the planet may host a weak thermal inversion. The data are equally well fit by atmospheric models with or without a thermal inversion. We find that variation in activity of solar-like stars does not change ...

Higgs quadruplet for the type III seesaw model and implications for {mu}{yields}e{gamma} and {mu}-e conversion  

SciTech Connect

In the type III seesaw model, the heavy neutrinos are contained in leptonic triplet representations. The Yukawa couplings of the triplet fermion and the left-handed neutrinos with the doublet Higgs field produce the Dirac mass terms. Together with the Majorana masses for the leptonic triplets, the light neutrinos obtain nonzero seesaw masses. We point out that it is also possible to have a quadruplet Higgs field to produce the Dirac mass terms to facilitate the seesaw mechanism. The vacuum expectation value of the quadruplet Higgs is constrained to be small by electroweak precision data. Therefore, the Yukawa couplings of a quadruplet can be much larger than those for a doublet. We also find that unlike the usual type III seesaw model where at least two copies of leptonic triplets are needed, with both doublet and quadruplet Higgs representations, just one leptonic triplet is possible to have a phenomenologically acceptable model because light neutrino masses can receive sizable contributions at both tree and one-loop levels. Large Yukawa couplings of the quadruplet can induce observable effects for lepton flavor violating processes {mu}{yields}e{gamma} and {mu}-e conversion. Implications of the recent {mu}{yields}e{gamma} limit from MEG and the limit on {mu}-e conversion on Au are also given. Some interesting collider signatures for the doubly charged Higgs boson in the quadruplet are discussed.

We supplement the 205 {mu}m data with new reductions of far-IR fine-structure spectra from the Infrared Space Observatory (ISO) Long Wavelength Spectrometer (LWS) in 63 {mu}m [O I], 122 {mu}m [N II], 146 {mu}m [O I], and 158 {mu}m [C II]; the 146 {mu}m [O I] data include 90 raster positions which have not been previously published. Morphological comparisons are made with optical, radio continuum, and CO maps. The 122/205 line ratio is used to probe the density of the low-ionization gas, and the 158/205 line ratio is used to probe the fraction of C{sup +} arising from photodissociation regions (PDRs). The [O I] and [C II] lines are used to construct a PDR model of Carina. When the PDR properties are compared with other sources, Carina is found to be more akin to 30 Doradus than galactic star-forming regions such as Orion, M17, or W49; this is consistent with the view of Carina as a more evolved region, where much of the parent molecular cloud has been ionized or swept away. These data constitute the first ground-based detection of the 205 {mu}m [N II] line, and the third detection overall since those of COBE FIRAS and the Kuiper Airborne Observatory in the early 1990s.

On the model discriminating power of mu to e conversion in nuclei  

SciTech Connect

Lepton Flavor Violating (LFV) charged lepton decays provide a highly sensitive probe of physics beyond the Standard Model (SM), due to the un-observably small branching fractions ({approx}10{sup -50}) predicted for these modes in the SM (minimally extended to include massive neutrinos). Searches for SM forbidden muon processes, such as {mu} {yields} e{gamma}, {mu} {yields} e{bar e}e, and {mu} {yields} e conversion in nuclei, have provided so far the strongest constraints on LFV new physics. This statement can be characterized in a model-independent way as a lower bound on the scale associated to a set of dimension six effective operators parameterizing new physics beyond the SM. It is a well known fact that while the decay {mu} {yields} e{gamma} is only sensitive to a transition magnetic dipole operator, both {mu} {yields} e{bar e}e and {mu} {yields} e conversion in nuclei are sensitive to transition charge radii operators as well as purely contact four-fermion interactions induced by physics beyond the SM. In other words, different LFV decays have different sensitivities to underlying LFV mechanisms (effective operators). This leads naturally to ask the question whether one could infer the relative strength of these different operators in a completely phenomenological and model-independent way. This would allow one to discriminate among different underlying models of LFV and thus would provide valuable input for model building. In Ref. [1] it was pointed out that in principle, by combining the rates of {mu} {yields} e{gamma} and {mu} {yields} e conversion on different target nuclei, one could discriminate underlying models. In this work we go back to this issue with the aim to: quantify the theoretical uncertainty induced by the hadronization process; and quantify the experimental precision required to realistically infer useful information on the underlying LFV mechanisms. We organize our discussion as follows: in Section 2 we review the derivation of the {mu} {yields} e conversion rate starting from a general effective theory description of the LFV physics. In Section 3 we explore the phenomenological consequence of the simplest possible models, in which only one effective LFV operator dominates. We extend this analysis in Section 4 to the class of models in which two operators dominate. In Section 5 we specialize our discussion to the SUSY see-saw model and summarize the conclusions of our analysis in Section 6.

Potential Operation and Maintenance (O&M) Savings at Schools in the Ft. Worth Independent School District  

E-Print Network (OSTI)

As part of the Texas LoanSTAR program, 44 schools in the Fort Worth Independent School District (FWISD) had lighting retrofits performed on there in late 1991. The Energy Systems Laboratory of Texas A&M University is monitoring hourly energy use at two of these 44 schools, Sims Elementary School and Dunbar Middle School. Data analyses at the Energy Systems Laboratory on the monitored data along with utility billing data from 102 other schools in the FWISD, have shown major O&M savings potential in these schools of over one-fourth of the total electricity consumption and gas consumption, which could amount to $ 1,658,000/yr. This report describes the analysis procedure and highlights the O&M energy savings potential in each of the 104 schools.

Routine {sup 18}F{sup -} production with 180 {mu}A to 200 {mu}A target beam current on a GE PETtrace 800 cyclotron  

SciTech Connect

Through upgrades and enhancements, which are now standard on current PETtrace 800 cyclotrons, a GE PETtrace cyclotron installed in 2002 has demonstrated reliable routine [{sup 18}F]FDG production at total target beam currents of 180 {mu}A without detriment to saturation and [{sup 18}F]FDG yields. Routine production at 200 {mu}A has been achieved and its evaluation is continuing. Self-shielded target using W/Cu alloy for the target body afforded a reduction in dose rate from the Havar foils by a factor of {approx} 8-10, reducing dose from the targets and need for removing targets during maintenance. The main activation product in the shield is {sup 187}W (T1/2 24 h). The {sup 60}Co ((T1/2 5.3 y) activation is about 250 times less at 24 h post EOB and is not considered a major issue despite its long half-life.

Design of a neutron penumbral-aperture microscope with 10-. mu. m resolution  

SciTech Connect

We are currently designing a 10-{mu}m resolution neutron penumbral-aperture microscope to diagnose high-convergence targets at the Nova laser facility. To achieve such high resolution, the new microscope will require substantial improvements in three areas. First, we have designed thick penumbral apertures with extremely sharp cutoffs over a useful ({approx}100 {mu}m) field of view; fabrication of such apertures appears feasible using gold electroplating techniques. Second, the limited field of view and required close proximity of the aperture to the target (2 cm) necessitates a durable mounting and alignment system with {plus}25 {mu}m accuracy. Finally, a neutron detector containing 160,000 scintillator elements is required; readout and optimization of this large array are outstanding issues. 5 refs., 3 figs.

The Mu2e experiment is being planned at Fermilab to measure the rate for muons to convert to electrons in the field of an atomic nucleus with unprecedented precision. This experiment uses an 8 GeV primary proton beam consisting of short ({approx}200 nsec FW) bunches, separated by 1.7 {mu}sec. It is vital that out-of-bunch beam be suppressed at the level of 10{sup -10} or less. This poster describes the parametric analysis which was done to determine the optimum harmonics and magnet specifications for this system, as well as the implications for the beam line optics.

Analysis of the charmed semileptonic decay D+ ---> rho0 mu+ nu  

SciTech Connect

The search for the fundamental constituents of matter has been pursued and studied since the dawn of civilization. As early as the fourth century BCE, Democritus, expanding the teachings of Leucippus, proposed small, indivisible entities called atoms, interacting with each other to form the Universe. Democritus was convinced of this by observing the environment around him. He observed, for example, how a collection of tiny grains of sand can make out smooth beaches. Today, following the lead set by Democritus more than 2500 years ago, at the heart of particle physics is the hypothesis that everything we can observe in the Universe is made of a small number of fundamental particles interacting with each other. In contrast to Democritus, for the last hundred years we have been able to perform experiments that probe deeper and deeper into matter in the search for the fundamental particles of nature. Today's knowledge is encapsulated in the Standard Model of particle physics, a model describing the fundamental particles and their interactions. It is within this model that the work in this thesis is presented. This work attempts to add to the understanding of the Standard Model by measuring the relative branching fraction of the charmed semileptonic decay D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu} with respect to D{sup +} {yields} {bar K}*{sup 0} {mu}{sup +}{nu}. Many theoretical models that describe hadronic interactions predict the value of this relative branching fraction, but only a handful of experiments have been able to measure it with any precision. By making a precise measurement of this relative branching fraction theorists can distinguish between viable models as well as refine existing ones. In this thesis we presented the measurement of the branching fraction ratio of the Cabibbo suppressed semileptonic decay mode D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu} with respect to the Cabibbo favored mode D{sup +} {yields} {bar K}*{sup 0} {mu}{sup +}{nu} using data collected by the FOCUS collaboration. We used a binned maximum log-likelihood fit that included all known semileptonic backgrounds as well as combinatorial and muonmisidentification backgrounds to extract the yields for both the signal and normalization modes. We reconstructed 320 {+-} 44 D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu} events and 11372 {+-} 161 D{sup +} {yields} K{sup -}{pi}{sup +}{mu}{sup +}{nu} events. Taking into account the non-resonant contribution to the D{sup +} {yields} K{sup -}{pi}{sup +}{mu}{sup +}{nu} yield due to a s-wave interference first measured by FOCUS the branching fraction ratio is: {Lambda}(D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu}) = 0.0412 {+-} 0.0057 {+-} 0.0040 (VII.1) where the first error is statistical and the second error is the systematic uncertainty. This represents a substantial improvement over the previous world average. More importantly, the new world average for {Lambda}(D{sup +}{yields}{rho}{sup 0}{mu}{sup +}{nu})/{Lambda}(D{sup +}{yields}{bar K}*{sup 0}{mu}{sup +}{nu}) along with the improved measurements in the electronic mode can be used to discriminate among different theoretical approaches that aim to understand the hadronic current involved in the charm to light quark decay process. The average of the electronic and muonic modes indicate that predictions for the partial decay width {Lambda}(D{sup +} {yields} {rho}{sup 0}{ell}{sup +}{nu}) and the ratio {Lambda}(D{sup +}{yields}{rho}{sup 0}{ell}{sup +}{nu})/{Lambda}(D{sup +}{yields}{bar K}*{sup 0}{ell}{sup +}{nu}) based on Sum Rules are too low. Using the same data used to extract {Lambda}(D{sup +}{yields}{rho}{sup 0}{mu}{sup +}{nu})/{Lambda}(D{sup +}{yields}{bar K}*{sup 0}{mu}{sup +}{nu}) we studied the feasibility of measuring the form factors for the D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu} decay. We found that the need to further reduce the combinatorial and muon misidentification backgrounds left us with a much smaller sample of 52 {+-} 12 D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{mu} events; not enough to make a statistically significa

POINTERs are nonstandard Fortran statements which cannot be processed by ADIFOR. We are interested in generating derivative code for MM5, a mesoscale model code which uses POINTERs extensively and in a particular structured manner. We briefly report on POINTERs and their role in MM5 and, for their particular usage in MM5, describe the three-step code transformation scheme consisting of pre-ADIFOR, ADIFOR, and post-ADIFOR transformations that result in the generation of correct derivative code for MM5.

We present a (2+1)-flavor lattice QCD calculation of the form factor ratio between the semileptonic decays {bar B}{sub s}{sup 0} {yields} D{sub s}{sup +}l{sup -}{bar {nu}} and {bar B}{sup 0} {yields} D{sup +}l{sup -}{bar {nu}}. This ratio is an important theoretical input to the hadronic determination of the B meson fragmentation fraction ratio f{sub s}/f{sub d} which enters in the measurement of BR(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}). Small lattice spacings and high statistics enable us to simulate the decays with a dynamic final D meson of small momentum and reliably extract the hadronic matrix elements at nonzero recoil. We report our preliminary result for the form factor ratio at the corresponding momentum transfer of the two decays f{sub 0}{sup (s)} (M{sub {pi}}{sup 2})/f{sub 0}{sup (d)} (M{sub K}{sup 2}).

Condensation heat transfer characteristics of R410A-oil mixture in 5 mm and 4 mm outside diameter horizontal microfin tubes  

Science Conference Proceedings (OSTI)

Condensation heat transfer characteristics of R410A-oil mixture in 5 mm and 4 mm outside diameter horizontal microfin tubes were investigated experimentally. The experimental condensing temperature is 40 C, and nominal oil concentration range is from 0% to 5%. The test results indicate that the presence of oil deteriorates the heat transfer. The deterioration effect is negligible at nominal oil concentration of 1%, and becomes obvious with the increase of nominal oil concentration. At 5% nominal oil concentration, the heat transfer coefficient of R410A-oil mixture is found to have a maximum reduction of 25.1% and 23.8% for 5 mm and 4 mm tubes, respectively. The predictabilities of the existing condensation heat transfer correlations were verified with the experimental data, and Yu and Koyama correlation shows the best predictability. By replacing the pure refrigerant properties with the mixture's properties, Yu and Koyama correlation has a deviation of -15% to + 20% in predicting the local condensation heat transfer coefficient of R410A-oil mixture.

Gauge origin of M parity and the {mu} term in supersymmetry  

SciTech Connect

In this article, we present a simple theoretical framework where the origin of the {mu} term and the matter-parity-violating interactions of the minimal supersymmetric standard model can be understood from the spontaneous breaking of new Abelian gauge symmetries. In this context, the masses of the Z{sup '} gauge bosons, the M-parity-violating scale and the {mu} term are determined by the supersymmetry breaking scale. The full spectrum of the theory is discussed in detail. We investigate the predictions for the Higgs masses in detail showing that it is possible to satisfy the LEP2 bounds even with sub-TeV squark masses. The model predicts the existence of light colored fields, lepton- and baryon-number violation, and new neutral gauge bosons at the Large Hadron Collider.

On the model discriminating power of mu -> e conversion in nuclei  

E-Print Network (OSTI)

We assess the model discriminating power of a combined phenomenological analysis of mu -> e gamma and mu -> e conversion on different target nuclei, including the current hadronic uncertainties. We find that the theoretical uncertainties can be largely reduced by using input from lattice QCD and do not constitute a limiting factor in discriminating models where one or at most two underlying operators (dipole, scalar, vector) provide the dominant source of lepton flavor violation. Our results show that a realistic discrimination among underlying mechanisms requires a measurement of the ratio of conversion rates at the 5% level (two light nuclei) or at the 20% level (one light and one heavy nucleus). We have illustrated these main conclusions also in the context of a supersymmetric model.

A low-energy solution to the mu-problem in gauge mediation  

E-Print Network (OSTI)

In the gauge-mediation framework the soft supersymmetry breaking mass parameters of the supersymmetric standard model are induced by the gauge interactions of some messenger fields. The parameters exhibit flavor universality which is dictated by the gauge interactions and which efficiently eliminates new dangerous contributions to flavor changing neutral currents. However, the Higgs potential in this framework typically contains an unacceptable hierarchy between its dimensionful parameters (the $\\mu$-problem of gauge mediation). We show that the problem can be resolved if the Higgs potential arises dynamically once an intermediate U(1)' sector is integrated out rather than arising radiatively from some Yukawa interactions at the messenger scale. As an added benefit, such models may naturally avoid new contribution to CP violating amplitudes. The proposed framework is described, explicit examples are given and its phenomenology is explored. The $\\mu$ problem is resolved in this case by the low-energy U(1)' dynamics which could be tested in future collider experiments.

Dosimetric and mechanical characteristics of a commercial dynamic {mu}MLC used in SRS  

Science Conference Proceedings (OSTI)

Purpose: The aim of this work is to carry out mechanical and dosimetric assessments on a commercial dynamic micromulti leaf collimator system to be used for stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT). Mechanical parameters such as leaf position accuracy with different gantry angles and leaf position reproducibility were measured. Also dosimetric measurements of the interleaf leakage, intraleaf transmission, penumbra width, and light field alignment were carried out. Furthermore, measurements of output factors (S{sub cp}) and in-air factors (S{sub c}) for the {mu}MLC system will be reported. Methods: EBT2 films were used to assess the leaf position error with gantry angle and after stress test, penumbra width and light field alignment. Leaf leakage was quantified using both EBT2 film and a pinpoint ion chamber. With regard to output factors, the pinpoint chamber was placed in a water phantom at 10 cm depth and 100 cm SSD. For in-air output factor measurements, 0.2 cm of brass was placed above the photon diode as build-up. Results: Measurements of mechanical parameters gave values of 0.05 cm (SD 0.035) for the average leaf position accuracy for different gantry angles and after stress test. Dosimetric measurements, yielded values of 0.22 {+-} 0.01 and 0.24 {+-} 0.01 cm, respectively, for side and head leaf penumbras. Also, average leaf abutting, leakage and transmission were found to be 0.65, 0.91, and 0.20%, respectively. Conclusions: (a) The add-on {mu}MLC system in combination with our LINAC has been commissioned to be used for clinical purposes and showed good agreement with published results for different {mu}MLC types. (b) This work has lead to the recommendation that leaves should be recalibrated after ten static beams or after each dynamic arc.

New Developments in TRI{mu}P and RIASH at KVI  

SciTech Connect

The status of the TRI{mu}P facility at KVI is reviewed. Recent results on ion catcher devices are described. A thermo-ionizer for use with alkali and earth-alkali elements is close to completion. Concerning the use of superfluid helium as stopping medium, evidence that second sound pulses can be used to extract ions from the helium surface has been obtained. Based on the observation of highly efficient ion transport in helium, neon and argon gas below about 100 K, we propose the operation of noble gas ion catchers at cryogenic temperatures.

Optimization of a Mu2e production solenoid heat and radiation shield using MARS15  

SciTech Connect

A Monte-Carlo study of several Mu2e Production Solenoid (PS) absorber (heat shield) versions using the MARS15 code has been performed. Optimizations for material as well as cost (amount of tungsten) have been carried out. Studied are such quantities as the number of displacements per atom (DPA) in the helium-cooled solenoid superconducting coils, power density and dynamic heat load in various parts of the PS and its surrounding structures. Prompt dose, residual dose, secondary particle flux are also simulated in the PS structures and the experimental hall. A preliminary choice of the PS absorber design is made on the ground of these studies.

Theta-13 as a Probe of Mu-Tau symmetry for Leptons  

E-Print Network (OSTI)

Many experiments are being planned to measure the neutrino mixing parameter $\\theta_{13}$ using reactor as well as accelerator neutrino beams. In this note, the theoretical significance of a high precision measurement of this parameter is discussed. It is emphasized that it will provide crucial information about different ways to understand the origin of large atmospheric neutrino mixing and move us closer towards determining the neutrino mass matrix. For instance if exact $\\mu\\leftrightarrow \\tau$ symmetry in the neutrino mass matrix is assumed to be the reason for maximal $\

Excited states of the bacteriochlorophyll b dimer of rhodopseudomonas viridis. A QM/MM study of the photosynthetic reaction center that includes MM polarization  

Science Conference Proceedings (OSTI)

We present a hybrid quantum mechanical/molecular mechanical (QM/MM) model for microscopic solvation effects that includes polarizability in the MM region (QM/MMpol). QM/MMpol treatment of both ground and excited states is presented in the formalism. We present QM/MMpol analysis of the ground and electronic excited states of the bacteriochlorophyll b dimer (P) of the photosynthetic reaction center (RC) of Rhodopseudomonas viridis using the INDO/S method. The static-charge potential from the MM model of the RC alone causes Q{sub y1} to have significantly better agreement with the Stark effect results than isolated P. However, consideration of the protein polarization potential is further required to obtain more complete agreement with Stark effect experiments. Thus, we calculate a Q{sub y1} transition energy at 10826 cm{sup -1} with a ground to excited state change in dipole moment of 4.8 D; an absorption Stark effect angle of 43{degree}; a net shift of 0.15 electrons from the L subunit to the M subunit of P; and a linear dichroism angle (between the transition moment of Q{sub y1} and the pseudo-C{sub 2} axis of the RC) of 81{degree}. These results are in good agreement with experiment. Interestingly, we find that net CT increase is greater for Q{sub y1} than for the second excited state of P (Q{sub y2}), a result that we anticipated in an early model dimer study. 77 refs., 3 figs., 2 tabs.

A Healthy Electron/Neutron EDM in D3/D7 mu-Split SUSY  

E-Print Network (OSTI)

Within the framework of N=1 gauged supergravity, using a phenomenological model which can be obtained locally as a Swiss-Cheese Calabi-Yau string-theoretic compactification with a mobile D3-brane localized on a nearly sLag three-cycle in the Calabi-Yau and fluxed stacks of wrapped D7-branes, and which provides a natural realization of mu-Split SUSY, we show that in addition to getting a significant value of electron/neutron EDM d_{e,n}/e at two-loop level, one can obtain a sizable contribution of d_{e,n}/e even at one-loop level. We obtain d_{e}/e ~ O(10^{-29}) cm from two-loop diagrams involving heavy sfermions and a light Higgs, and d_{e}/e ~ O(10^{-32}) cm from one-loop diagram involving heavy chargino and a light Higgs. Also, d_{n}/e ~ O(10^{-33}) cm from one-loop diagram involving SM-like quarks and Higgs. Next, by considering a Barr-Zee diagram involving W bosons and Higgs, and conjecturing that the CP-violating phase can appear from a linear combination of Higgs doublet obtained in the context of mu-split SUSY, we obtain d_{e,n}/e ~ O(10^{-27}) cm at two-loop level .

WATER-AMMONIUM ICES AND THE ELUSIVE 6.85 {mu}m BAND  

Science Conference Proceedings (OSTI)

The 6.85 {mu}m band observed in the spectra of young stellar objects has been analyzed recently and the most usually accepted assignment to the nu{sub 4} bending mode of NH{sub 4} {sup +} is still under debate. We present here a laboratory study of frozen solutions of NH{sub 4} {sup +}Cl{sup -} in water in an astrophysical range of concentrations and temperatures. The samples are prepared by hyper-quenching of liquid droplets on a cold substrate. The nu{sub 4} band of NH{sub 4} {sup +}, which is very strong in the pure crystal and in the liquid solution at ambient temperature, becomes almost blurred in IR spectra of the frozen solution. The effect of the chlorine anion is expected to be of little relevance in this study. The experimental results are supported by theoretical calculations, which predict a broad range of weak nu{sub 4} features for amorphous samples containing different ammonium environments. The present results indicate that the ammonium ion surrounded by water molecules only cannot suffice to explain this spectral feature. This paper contributes with new evidence to the discussion on the assignment of the 6.85 {mu}m band.

A Circulating Hydrogen Ultra-High Purification System for the MuCap Experiment  

E-Print Network (OSTI)

The MuCap experiment is a high-precision measurement of the rate for the basic electroweak process of muon capture, mu- + p -> n + nu . The experimental approach is based on an active target consisting of a time projection chamber (TPC) operating with pure hydrogen gas. The hydrogen has to be kept extremely pure and at a stable pressure. A Circulating Hydrogen Ultrahigh Purification System was designed at the Petersburg Nuclear Physics Institute (PNPI) to continuously clean the hydrogen from impurities. The system is based on an adsorption cryopump to stimulate the hydrogen flow and on a cold adsorbent for the hydrogen cleaning. It was installed at the Paul Scherrer Institute (PSI) in 2004 and performed reliably during three experiment runs. During several months long operating periods the system maintained the hydrogen purity in the detector on the level of 20 ppb for moisture, which is the main contaminant, and of better than 7 ppb and 5 ppb for nitrogen and oxygen, respectively. The pressure inside the TPC was stabilized to within 0.024% of 10 bar at a hydrogen flow rate of 3 standard liters per minute.

A red supergiant nebula at 25 micron: arcsecond scale mass-loss asymmetries of mu Cep  

E-Print Network (OSTI)

We present diffraction limited (0.6") 24.5micron Subaru/COMICS images of the red supergiant mu Cep. We report the detection of a circumstellar nebula, that was not detected at shorter wavelengths. It extends to a radius of at least 6" in the thermal infrared. On these angular scales, the nebula is roughly spherical, in contrast, it displays a pronounced asymmetric morphology closer in. We simultaneously model the azimuthally averaged intensity profile of the nebula and the observed spectral energy distribution using spherical dust radiative transfer models. The models indicate a constant mass-loss process over the past 1000 years, for mass-loss rates a few times 10^(-7) Msun/yr. This work supports the idea that at least part of the asymmetries in shells of evolved massive stars and supernovae may be due to the mass-loss process in the red supergiant phase.

Water vapor transmittance models for narrow bands in the 13 to 19. mu. m spectral region  

Science Conference Proceedings (OSTI)

The purpose of this report is to document the development of water vapor transmittance models for narrow bands (satellite sensor channels) in the 13 to 19 ..mu..m spectral region. The models are the result of research efforts of the author in 1971-1972 while on active duty with the US Air Force at the Air Force Global Weather Central (AFGWC). The models were developed for application in studies involving a temperature profiling sensor system carried aboard the satellites of the Defense Meteorological Satellite Program (DMSP), formerly DAPP. Recently, (Lovill et al., 1978; Luther et al., 1981) the models were implemented for studies concerned with methodologies to retrieve total atmospheric column ozone from measurements of newer DMSP Block 5D series satellite sensors with similar channels (see Nichols, 1975).

Energy transfer and 1.54 {mu}m emission in amorphous silicon nitride films  

Science Conference Proceedings (OSTI)

Er-doped amorphous silicon nitride films with various Si concentrations (Er:SiN{sub x}) were fabricated by reactive magnetron cosputtering followed by thermal annealing. The effects of Si concentrations and annealing temperatures were investigated in relation to Er emission and excitation processes. Efficient excitation of Er ions was demonstrated within a broad energy spectrum and attributed to disorder-induced localized transitions in amorphous Er:SiN{sub x}. A systematic optimization of the 1.54 {mu}m emission was performed and a fundamental trade-off was discovered between Er excitation and emission efficiency due to excess Si incorporation. These results provide an alternative approach for the engineering of sensitized Si-based light sources and lasers.

Absolute Current Calibrations of 1muA CW Electron Beam  

SciTech Connect

The future experimental program at Jefferson Lab requires an absolute current calibration of a 1{mu}A CW electron beam to better than 1% accuracy. This paper presents the mechanical and electrical design of a Tungsten calorimeter that is being constructed to provide an accurate measurement of the deposited energy. The energy is determined by measuring the change in temperature after beam exposure. Knowledge of the beam energy then yields number of electrons stopped by the calorimeter during the exposure. Simulations show that the energy losses due to electromagnetic and hadronic losses are the dominant uncertainty. Details of the precision thermometry and calibration, mechanical design, thermal simulations and GEANT simulations will be presented.

Studies of Nu-mu to Nu-e Oscillation Appearance in the MINOS Experiment  

SciTech Connect

The MINOS experiment uses a long baseline neutrino beam, measured 1 km downstream from its origin in the Near Detector at Fermilab, and 734 km later in the large underground Far Detector in the Soudan mine. By comparing these two measurements, MINOS can probe the atmospheric domain of the neutrino oscillation phenomenology with unprecedented precision. Besides the ability to perform a world leading determination of the {Delta}m{sub 23}{sup 2} and {theta}{sub 23} parameters, via {nu}{sub {mu}} flux disappearance, MINOS has the potential to make a leading measurement of {nu}{sub {mu}} {yields} {nu}{sub e} oscillations in the atmospheric sector by looking for {nu}{sub e} appearance at the Far Detector. The observation of {nu}{sub e} appearance, tantamount to establishing a non-zero value of the {theta}{sub 13} mixing angle, opens the way to studies of CP violation in the leptonic sector, the neutrino spectral mass pattern ordering and neutrino oscillations in matter, the driving motivations of the next generation of neutrino experiments. In this thesis, we study the MINOS potential for measuring {theta}{sub 13} in the context of the MINOS Mock Data Challenge using a multivariate discriminant analysis method. We show the method's validity in the application to {nu}{sub e} event classification and background identification, as well as in its ability to identify a {nu}{sub e} signal in a Mock Data sample generated with undisclosed parameters. An independent shower reconstruction method based on three-dimensional hit matching and clustering was developed, providing several useful discriminator variables used in the multivariate analysis method. We also demonstrate that within 2 years of running, MINOS has the potential to improve the current best limit on {theta}{sub 13}, from the CHOOZ experiment, by a factor of 2.

Water vapor on supergiants. The 12 micron TEXES spectra of mu Cephei  

E-Print Network (OSTI)

Several recent papers have argued for warm, semi-detached, molecular layers surrounding red giant and supergiant stars, a concept known as a MOLsphere. Spectroscopic and interferometric analyses have often corroborated this general picture. Here, we present high-resolution spectroscopic data of pure rotational lines of water vapor at 12 microns for the supergiant mu Cephei. This star has often been used to test the concept of molecular layers around supergiants. Given the prediction of an isothermal, optically thick water-vapor layer in Local Thermodynamic Equilibrium around the star (MOLsphere), we expected the 12 micron lines to be in emission or at least in absorption but filled in by emission from the molecular layer around the star. Our data, however, show the contrary; we find definite absorption. Thus, our data do not easily fit into the suggested isothermal MOLsphere scenario. The 12 micron lines, therefore, put new, strong constraints on the MOLsphere concept and on the nature of water seen in signatures across the spectra of early M supergiants. We also find that the absorption is even stronger than that calculated from a standard, spherically symmetric model photosphere without any surrounding layers. A cool model photosphere, representing cool outer layers is, however, able to reproduce the lines, but this model does not account for water vapor emission at 6 microns. Thus, a unified model for water vapor on mu Cephei appears to be lacking. It does seem necessary to model the underlying photospheres of these supergiants in their whole complexity. The strong water vapor lines clearly reveal inadequacies of classical model atmospheres.

DOE Green Energy (OSTI)

This paper describes a 650 mm long liquid hydrogen targetr constructed for use in the high intensity electron beam at the Stanford Linear Accelerator Center (SLAC). The main design problem was to construct a target that would permit the heat deposited by the electron beam to be removed rapidly without boiling the hydrogen so as to maintain constant target density for optimum data taking. Design requirements, cosntruction details and operating experience are discussed.

SciTech Connect

A high power ({approx}3 kW) target platform has been developed for the IBA 18/9 cyclotron. New designs for the airlock, collimator and target subsystems have been fabricated and deployed. The primary project goal is reliable commercial production of 18F{sup -} at 150 {mu}A or greater, while secondary goals include improving serviceability and extending service intervals relative to OEM systems. Reliable operation in a production environment has been observed at beam currents up to 140 {mu}A. Challenges include ion source lifetime and localized peaking in the beam intensity distribution.

SEARCH FOR CHARGED PARTICLES WITH REST MASS BETWEEN THAT OF THE ELECTRON AND MU-MESON  

SciTech Connect

An attempt was made to produce charged particles with rest mass between that of the electron and mu meson (hereafter called submuons) by electromagnetic pair pronduction from C nuclei. The incident photon beam was obtained by bombarding a thick C block with an 800-Mev electron beam. The same block served as the target for the production process. Only one member of the produced pair was to be observed. The momentum of the secondary particles (300 Mev/c) was determined by a zero-dispersion, doublefocusing magnetic spectrometer. The particles traversing the spectrometer were detected by a 6-courter telescope, in which the counters were separated by various thicknesses of lead. The signals from the counters were put in coincidence in a 6-channel fast-resolution coincidence circuit. The telescope was sensitive to submuons with rest masses between 175 and 10 electron masses. The expected counting rates were calculated using the Bethe-Heitler and Pauli-Weisskopf formulas for spin 1/2 and spin 0 submuons, respectively. An integration over the variables of the unobserved member of the pair, and thus over the momentum transfer to the C nucleus was performed. The nucleus was treated by a sum rale calculation to take into account both the finite nuclear size and the elastic and inelastic contributions to the cross section. The resulting cross sections were multiplied by the total photon spectrum and the results integrated over the available photon energy. The total photon spectrum included both the real photon spectrum from electron bremsstrshlung in the C target and the virtual photon spectrum associated with the electrons themselves. The expected courting rates varied from 70 to 12,500 counts per l0t7 incident electrons for spin 1/2 submuons with rest masses between 175 and 25 electron masses and half lives in the microsecond region or longer. The similar rates for spin 0 submuons were 10 to 2870 counts. Since only 4.10 plus or minus 2.05 counts per 10/sup 17/ incident electrons were observed, it seems highly unlikely thai particles with rest mass between that of the electron and mu-meson exist.

FIRST SCIENCE OBSERVATIONS WITH SOFIA/FORCAST: 6-37 {mu}m IMAGING OF ORION BN/KL  

SciTech Connect

The Becklin-Neugebauer/Kleinmann-Low (BN/KL) region of the Orion Nebula is the nearest region of high-mass star formation in our galaxy. As such, it has been the subject of intense investigation at a variety of wavelengths, which have revealed it to be brightest in the infrared to submillimeter wavelength regime. Using the newly commissioned SOFIA airborne telescope and its 5-40 {mu}m camera FORCAST, images of the entire BN/KL complex have been acquired. The 31.5 and 37.1 {mu}m images represent the highest resolution observations ({approx}<4'') ever obtained of this region at these wavelengths. These observations reveal that the BN object is not the dominant brightness source in the complex at wavelengths {>=} 31.5 {mu}m and that this distinction goes instead to the source IRc4. It was determined from these images and derived dust color temperature maps that IRc4 is also likely to be self-luminous. A new source of emission has also been identified at wavelengths {>=} 31.5 {mu}m that coincides with the northeastern outflow lobe from the protostellar disk associated with radio source I.

Neutrino interactions with e/sup +/. mu. /sup -/ and multiple K/sup 0/'s. [Branching ratio  

DOE Green Energy (OSTI)

A scan for directly produced positrons in 5,000 neutrino interactions in the neon (21 percent) hydrogen filled bubble chamber at Fermilab has yielded 15 events, 9 of which have ..mu../sup -/'s identified in the external muon identifier. On correcting for detection efficiency one obtains sigma(e/sup +/..mu../sup -/)/sigma(..mu../sup -/) approximately 1 x 10/sup -2/ for E/sub e/sup +// > .8 GeV and E/sub ..nu../ > 5 GeV. The kaon multiplicity is unexpectedly high. Eleven of the events have one or more Vees and three have two or more. Among the 11 events are two clear ..lambda..'s and two ambiguous K/sup 0//..lambda... There are four events with identifiable charged kaons. A 16th e/sup +/ event (9) is a definite ..nu../sub e/. From this information one concludes that the kaon multiplicity is 2 +- .6 K/sup 0/'s and 2 +- 1 K/sup + -/'s per interaction. From the observation

mu../sup -//>/

= 6.6, one concludes that the e/sup +/'s are probably not uniquely from heavy lepton decay. From a variety of analyses involving the e/sup +/ and/or K/sup 0/'s one learns that the mass of the hadron (C) that produces the e/sup +/'s is greater than 1.6 GeV. By determining the fraction of normal charged current (CC) events that have K/sup 0//sub s/ ..-->.. ..pi../sup +/..pi../sup -/ one is able to compare this fraction with the fraction of CC events that have e/sup +/..mu../sup -/ (K/sup 0//sub s/ ..-->.. ..pi../sup +/..pi../sup -/) to establish a conservative lower limit to the semileptonic branching ratio, C ..-->.. (e/sup +/ and ..mu../sup +/) ..nu../C ..-->.. all > 0.33 (1 +- .42), provided that the same number of K/sup 0//sub s/ exists in thenonleptonic decays as in the semileptonic ones, and that the phase space for ..mu../sup +/ and e/sup +/ are nearly equal. There is no compelling evidence for an energy threshold and there is a hint of some neutral current events among the e/sup +/ events.

Optimization of Extinction Efficiency in the 8-GeV Mu2e Beam Line  

SciTech Connect

A muon-to-electron conversion experiment at Fermilab, Mu2e, is being designed to probe for new physics beyond the standard model at mass scales up to 10{sup 4} TeV. For this experiment, the advance in experimental sensitivity will be four orders of magnitude when compared to existing data on charged lepton flavor violation. The muon beam will be produced by delivering a proton beam contained in short 100-ns bunches onto a muon production target, with an inter-bunch separation of about 1700 ns. A critical requirement of the experiment is to ensure a low level of background at the muon detector consistent with the required sensitivity. To meet the sensitivity requirement, protons that reach the target between bunches must be suppressed by an enormous factor, so that an extinction factor, defined as a number of background protons between main bunches per proton in such a bunch, should not exceed 10{sup -9}. This paper describes the advanced beam optics and results of numerical modeling with STRUCT and MARS codes for a beam line with a collimation system that allows us to achieve the experimental extinction factor of one per billion.

It is based on the CERN ROOT framework and is utilizing the Minuit optimization routines for fitting. It consists of a set of programs allowing the user to analyze and visualize the data. The fitting process is controlled by an ascii-input file with an extended syntax. A dedicated text editor is helping the user to create and handle these files in an efficient way, execute the fitting, show the data, get online help, and so on. A versatile tool for the generation of new input files and the extraction of fit parameters is provided as well. musrfit facilitates a plugin mechanism allowing to invoke user-defined functions.

The muonic He atom and a preliminary study of the He-4 mu + H-2 reaction  

DOE Green Energy (OSTI)

The muonic atom 4Heu has the composition a++u-e-, and is formed by stopping negative muons in He doped with a small amount of NH3 (or Xe). It may be regarded as a unique heavy H-atom isotope with a mass of 4.1 amu. As such, the study of its chemical reaction rates and comparison with those of the well-known light Mu atom (0.113amu) allows unprecedented tests of kinetic isotope effects over a range of 36 in mass. As a first example, and one which is of most fundamental interest, we have begun kinetics studies of the Heu + H2 - HeuH + H reaction in the gas phase. The first measurements, at 295K, give a rate constant of kHei = 4:1 - 0:7 x 10-16 cm3 molec-1 s-1. In comparison, variational transition state calculations give a value of 2:46 x 10-16 cm3 molec-1 s-1, some what below the measurement, despite the large error bar, raising the possibility that the calculations, on a nessentially exact potential energy surface, have underestimated the amount of quantum tunneling involved, even for this heavyH-atom isotope.

86 GHz polarimetry of OVV1633+382 after a major mm flare  

E-Print Network (OSTI)

The 18 mag QSO 1633+382 (4C38.41, z=1.807) showed a very pronounced outburst in 2001/2002. With a peak amplitude of more than 9 Jy at 90GHz, this flare was brighter than any known previous flare in this source (data available since 1980).During onset, the mm-flare was particulary fast, with an increase of more than 2 Jy at 230 GHz in less than 8 days. Since January 2002, the mm-flux of 1633+382 is decaying. During this decline, however, local flux variations with amplitudes of 1-3 Jy were seen, indicative of underlying and more rapid source activity on time scales of 1-2 months. After the main peak occurring in 2001.99, the 90 GHz flux showed secondary maxima at approximately half year intervals in 2002.3, 2002.7 and 2003.13. This kind of periodicity might be explained via the lighthouse model (Camenzind and Krockenberger 1992), which is based on the magnetic accelerator of Blanford and Payne (1982). At present the millimeter flux is nearly back to its quiescent level of 2-2.5 Jy, which the source had before ...

Customer Equilibrium and Optimal Strategies in an M/M/1 Queue with Dynamic Service Control  

E-Print Network (OSTI)

We consider the problem of customer equilibrium strategies in an M/M/1 queue under dynamic service control. The service rate switches between a low and a high value depending on system congestion. Arriving customers do not observe the system state at the moment of arrival. We show that due to service rate variation, the customer equilibrium strategy is not generally unique, and derive an upper bound on the number of possible equilibria. For the problem of social welfare optimization, we numerically analyze the relationship between the optimal arrival rate, which maximizes the overall welfare of the customers, and the equilibrium ones as a function of various parameter values. We finally derive analytic solutions for the special case where the service rate switch occurs when the queue ceases to be empty.

After discussing the method, we demonstrate its potential with an example of the radiative recoil corrections to the Lamb shift and hyperfine splitting relevant for the hydrogen, muonic hydrogen, and muonium. A discrepancy between two previous calculations of O({alpha}(Z{alpha}){sup 5} m{sup 2}/M) radiative recoil corrections to the Lamb shift is resolved and several new terms of O({alpha}(Z{alpha}){sup 5} m{sup 4}/M{sup 3}) and higher are obtained.

Assessing the Performance of 5mm White LED Light Sources forDeveloping-Country Applications  

DOE Green Energy (OSTI)

Some white light-emitting diode (LED) light sources haverecently attained levels of efficiency and cost that allow them tocompete with fluorescent lighting for off-grid applications in thedeveloping world. Additional attributes (optics, size, ruggedness, andservice life) make them potentially superior products. Enormousreductions in energy use and greenhouse-gas emissions are thus possible,and system costs can be much lower given the ability to downsize thecharging and energy storage components compared to a fluorescentstrategy. However, there is a high risk of "market-spoiling" if inferiorproducts are introduced and result in user dissatisfaction. Completesystems involve the integration of light sources and optics, energysupply, and energy storage. A natural starting point for evaluatingproduct quality is to focus on the individual light sources. This reportdescribes testing results for batches of 10 5mm white LEDs from 26manufacturers. Efficacies and color properties are presented.

Measurement of transmission efficiency for 400 MeV proton beam through collimator at Fermilab MuCool Test Area using Chromox-6 scintillation screen  

SciTech Connect

The MuCool Test Area (MTA) at Fermilab is a facility to develop the technology required for ionization cooling for a future Muon Collider and/or Neutrino Factory. As part of this research program, feasibility studies of various types of RF cavities in a high magnetic field environment are in progress. As a unique approach, we have tested a RF cavity filled with a high pressure hydrogen gas with a 400 MeV proton beam in an external magnetic field (B = 3 T). Quantitative information about the number of protons passing through this cavity is an essential requirement of the beam test. The MTA is a flammable gas (hydrogen) hazard zone. Due to safety reasons, no active (energized) beam diagnostic instrument can be used. Moreover, when the magnetic field is on, current transformers (toroids) used for beam intensity measurements do not work due to the saturation of the ferrite material of the transformer. Based on these requirements, we have developed a passive beam diagnostic instrumentation using a combination of a Chromox-6 scintillation screen and CCD camera. This paper describes details of the beam profile and position obtained from the CCD image with B = 0 T and B = 3 T, and for high and low intensity proton beams. A comparison is made with beam size obtained from multi-wires detector. Beam transmission efficiency through a collimator with a 4 mm diameter hole is measured by the toroids and CCD image of the scintillation screen. Results show that the transmission efficiency estimated from the CCD image is consistent with the toroid measurement, which enables us to monitor the beam transmission efficiency even in a high magnetic field environment.

The Mu3e experiment searches for the lepton flavour violating decay mu+ -> e+e-e+, aiming for a branching fraction sensitivity of 10^-16. This requires an excellent momentum resolution for low energy electrons, high rate capability and a large acceptance. In order to minimize multiple scattering, the amount of material has to be as small as possible. These challenges can be met with a tracker built from high-voltage monolithic active pixel sensors (HV-MAPS), which can be thinned to 50 um and which incorporate the complete read-out electronics on the sensor chip. To further minimise material, the sensors are supported by a mechanical structure built from 25 um thick Kapton foil and cooled with gaseous helium.

Positive-tone silylated, dry-developed, deep ultraviolet resist with 0. 2 [mu]m resolution  

SciTech Connect

This paper describes the development of a surface-imaging process for a positive-tone silylated, dry-developed bilayer resist which has 0.2 [mu]m resolution and an aspect ratio of 4.5 using deep-UV (248 nm) exposure. The many processing variables such as thermal treatment parameters, silylation conditions, and etching conditions were examined to determine their effects on lithographic performance in terms of resolution, feature size linearity, focus latitude, and sensitivity. Critical to the success of the process are: the bilayer structure which restricts diffusion of the Si, the use of a disilane reagent to increase the Si content of the masking layer, limiting migration of photogenerated acid by the appropriate choice of softbake and post-exposure bake temperatures, initial etching with an Ar/Cl[sub 2] mixture to remove the thin layer of silylated resist in the exposed areas, and employing CO[sub 2] instead of O[sub 2] as the etching gas to eliminate lateral etching of the features. With this process we have obtained good critical dimension linearity down to 0.25 [mu]m for bright-field and dark-field lines and spaces as well as isolated lines and isolated spaces. The dose required is [similar to]75 mJ/cm[sup 2] and the dose latitude is [plus minus]6%. Focus latitude is at least [plus minus]0.4 [mu]m. We also observe no environmental effects on sensitivity or resolution.

It has been suggested that there is a correlation between stellar activity and the presence of inversions, so we analysed existing HARPS spectra in order to calculate log R'HK for WASP-24 and thus determine whether or not the star is chromospherically active. We also observed a transit of WASP-24b in the Str\\"{o}mgren u and y bands, with the CAHA 2.2-m telescope. Results. We measure occultation depths of 0.159 \\pm 0.013 per cent at 3.6 {\\mu}m and 0.202 \\pm 0.018 per cent at 4.5 {\\mu}m. The corresponding planetary brightness temperatures are 1974 \\pm 71 K and 1944 \\pm 85 K respectively. Atmosphere models with and without a thermal inversion fit the data equally well; we are unable to constrain the presence of an inversion without additional oc...

Rapid Variability: What do we learn from correlated mm-/gamma-ray variability in jets ?  

E-Print Network (OSTI)

Densely time sampled multi-frequency flux measurements of the extreme BL Lac object S5 0716+714 over the past three years allow us to study its broad-band variability, and the detailed underlying physics, with emphasis on the location and size of the emitting regions and the evolution with time. We study the characteristics of some prominent mm-/gamma-ray flares in the context of the shock-in-jet model and investigate the location of the high energy emission region. The rapid rise and decay of the radio flares is in agreement with the formation of a shock and its evolution, if a geometrical variation is included in addition to intrinsic variations of the source. We find evidence for a correlation between flux variations at gamma-ray and radio frequencies. A two month time-delay between gamma-ray and radio flares indicates a non-cospatial origin of gamma-rays and radio flux variations in S5 0716+714.

Operations, Maintenance, and Replacement 10-year plan, 1990-1999 : 1989 Utility OM&R Comparison : A Comparison of BPA (Bonneville Power Administration) and Selected Utility Transmission, Operations and Maintenance Costs.  

SciTech Connect

For the past several years, competing resource demands within BPA have forced the Agency to stretch Operations, Maintenance and Replacement (OM R) resources. There is a large accumulation of tasks that were not accomplished when scheduled. Maintenance and replacements and outages, due to material and equipment failure, appear to be increasing. BPA has made a strategic choice to increase its emphasis on OM R programs by implementing a multi-year, levelized OM R plan which is keyed to high system reliability. This strategy will require a long-term commitment of a moderate increase in staff and dollars allocated to these programs. In an attempt to assess the direction BPA has taken in its OM R programs, a utility comparison team was assembled in early January 1989. The team included representatives from BPA's Management Analysis, Internal Audit and Financial Management organizations, and operation and maintenance program areas. BPA selected four utilities from a field of more than 250 electric utilities in the US and Canada. The selection criteria generally pertained to size, with key factors including transformation capacity, load, gross revenue, and interstate transmission and/or marketing agreements, and their OM R programs. Information was gathered during meetings with managers and technical experts representing the four utilities. Subsequent exchanges of information also took place to verify findings. The comparison focused on: Transmission operations and maintenance program direction and emphasis; Organization, management and implementation techniques; Reliability; and Program costs. 2 figs., 21 tabs.

Efficient pulsed Cr{sup 2+}:CdSe laser continuously tunable in the spectral range from 2.26 to 3.61 {mu}m  

SciTech Connect

The efficient lasing of a Cr{sup 2+}:CdSe single crystal pumped by 1.94-{mu}m, 300-{mu}s pulses from a Tm:YAP laser was obtained. The Cr{sup 2+}:CdSe laser with a nonselective resonator emitted up to 17 mJ at a wavelength of {approx}2.65 {mu}m with the quantum slope efficiency of 63% with respect to the absorbed pump energy. The absorption coefficient of the Cr{sup 2+}:CdSe crystal at the laser wavelength did not exceed 0.045 cm{sup -1}. By using a resonator with a dispersion prism, the laser wavelength was continuously tuned in the spectral range from 2.26 to 3.61 {mu}m. (lasers)

FIRST SCIENCE OBSERVATIONS WITH SOFIA/FORCAST: 6-37 {mu}m IMAGING OF THE CENTRAL ORION NEBULA  

Science Conference Proceedings (OSTI)

We present new mid-infrared images of the central region of the Orion Nebula using the newly commissioned Stratospheric Observatory For Infrared Astronomy airborne telescope and its 5-40 {mu}m camera FORCAST. The 37.1 {mu}m images represent the highest resolution observations ({approx}<4'') ever obtained of this region at these wavelengths. After BN/KL (which is described in a separate paper in this issue), the dominant source at all wavelengths except 37.1 {mu}m is the Ney-Allen Nebula, a crescent-shaped extended source associated with {theta}{sup 1} D Ori. The morphology of the Ney-Allen nebula in our images is consistent with the interpretation that it is ambient dust swept up by the stellar wind from {theta}{sup 1} D Ori, as suggested by Smith et al. in 2005. Our observations also reveal emission from two 'proplyds' (proto-planetary disks), and a few embedded young stellar objects (YSOs; IRc 9, and OMC1-S IRS1, 2, and 10). The spectral energy distribution for IRc 9 is presented and fitted with standard YSO models from Robitaille et al. in 2007 to constrain the total luminosity, disk size, and envelope size. The diffuse, nebular emission we observe at all FORCAST wavelengths is most likely from the background photodissociation region (PDR) and shows structure that coincides roughly with H{alpha} and [N II] emission. We conclude that the spatial variations in the diffuse emission are likely due to undulations in the surface of the background PDR.

Measurement of the nu(mu)-CCQE cross-section in the SciBooNE experiment  

SciTech Connect

SciBooNE is a neutrino and anti-neutrino cross-section experiment at Fermilab, USA. The SciBooNE experiment is summarized and two independent CCQE analyses are described. For one of the analyses, an absolute {nu}{sub {mu}}-CCQE cross section in the neutrino energy region (0.6-1.6) GeV is shown and the technique developed for such a purpose is also explained. The total cross section measured over this energy range agrees well with expectations, based on the NEUT event generator and using a value of 1.21 GeV for the CCQE axial mass.

$B_s\\to D_s/B\\to D$ Semileptonic Form-Factor Ratios and Their Application to BR($B^0_s\\to \\mu^+\\mu^-$)  

SciTech Connect

We calculate form-factor ratios between the semileptonic decays {bar B}{sup 0} {yields} D{sup +} {ell}{sup -}{bar {nu}} and {bar B}{sub s}{sup 0} {yields} D{sub s}{sup +}{ell}{sup -}{bar {nu}} with lattice QCD. These ratios are a key theoretical input in a new strategy to determine the fragmentation fractions of the neutral B decays, which are needed for measurements of BR(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -}). They use the MILC ensembles of gauge configurations with 2 + 1 flavors of sea quarks at two lattice spacings of approximately 0.12 fm and 0.09 fm. We use the model-independent z parametrization to extrapolate their simulation results at small recoil toward maximum recoil. The results for the form-factor ratios are {line_integral}{sub 0}{sup (s)} (M{sub {pi}}{sup 2})/{line_integral}{sub 0}{sup (d)} (M{sub K}{sup 2}) = 1.046(44){sub stat.}(15){sub syst.} and {line_integral}{sub 0}{sup (s)} (M{sub {pi}}{sup 2})/{line_integral}{sub 0}{sup (d)} (M{sub {pi}}{sup 2}) = 1.054(47){sub stat.}(17){sub syst.}. In contrast to a QCD sum-rule calculation, no significant departure from U-spin (d {leftrightarrow} s) symmetry is observed.

The south central Texas heavy rain event of October 1998: an MM5 simulation and diagnosis of convective initiation  

E-Print Network (OSTI)

During the weekend of 17-18 October 1998, extremely heavy rainfall over south central Texas resulted in widespread flash flooding and numerous river floods. Southern Hays County received 760 mm of rainfall, and an area of 18,000 km² recorded over 250 mm. The convection began in a weakly forced environment well ahead of a cold front that was forecast to trigger the storms. The Penn State University/NCAR Mesoscale Model version 5 (MM5) was used to diagnose the extent and magnitude of upward motion, the convective potential of the environment, and the causes of the upward motion that contributed to the convective initiation. A rainfall analysis constructed from all available observations and radar estimates was used for a quantitative comparision with the MM5-simulated rainfall. The MM5's success in simulating many aspects of the rainfall suggested that the atmospheric processes that brought about this heavy rain event were also present in the model simulation. Using a 48-km model grid, upward motion was found to be more than sufficient to cause deep convection in the conditionally unstable atmosphere of south Texas. The cause of the upward motion was attributed to differential warm advection focused by a low-level jet centered over the region where convection began.

THE MASS LOSS RETURN FROM EVOLVED STARS TO THE LARGE MAGELLANIC CLOUD: EMPIRICAL RELATIONS FOR EXCESS EMISSION AT 8 AND 24 {mu}m  

SciTech Connect

We present empirical relations describing excess emission from evolved stars in the Large Magellanic Cloud (LMC) using data from the Spitzer Space Telescope Surveying the Agents of a Galaxy's Evolution (SAGE) survey which includes the Infrared Array Camera (IRAC) 3.6, 4.5, 5.8, and 8.0 {mu}m and Multiband Imaging Photometer (MIPS) 24, 70, and 160 {mu}m bands. We combine the SAGE data with the Two Micron All Sky Survey (2MASS; J, H, and K {sub s}) and the optical Magellanic Cloud Photometric Survey (MCPS; U, B, V, and I) point source catalogs in order to create complete spectral energy distributions (SEDs) of the asymptotic giant branch (AGB) star candidates in the LMC. AGB star outflows are among the main producers of dust in a galaxy, and this mass loss results in an excess in the fluxes observed in the 8 and 24 {mu}m bands. The aim of this work is to investigate the mass loss return by AGB stars to the interstellar medium of the LMC by studying the dependence of the infrared excess flux on the total luminosity. We identify oxygen-rich, carbon-rich, and extreme AGB star populations in our sample based on their 2MASS and IRAC colors. The SEDs of oxygen- and carbon-rich AGB stars are compared with appropriate stellar photosphere models to obtain the excess flux in all the IRAC bands and the MIPS 24 {mu}m band. Extreme AGB stars are dominated by circumstellar emission at 8 and 24 {mu}m; thus we approximate their excesses with the flux observed in these bands. We find about 16,000 O-rich, 6300 C-rich, and 1000 extreme sources with reliable 8 {mu}m excesses, and about 4500 O-rich, 5300 C-rich, and 960 extreme sources with reliable 24 {mu}m excesses. The excesses are in the range 0.1 mJy to 5 Jy. The 8 and 24 {mu}m excesses for all three types of AGB candidates show a general increasing trend with luminosity. The color temperature of the circumstellar dust derived from the ratio of the 8 and 24 {mu}m excesses decreases with an increase in excess, while the 24 {mu}m optical depth increases with excess. The extreme AGB candidates are the major contributors to the mass loss, and we estimate the total AGB mass loss return to the LMC to be (5.9-13) x 10{sup -3} M {sub sun} yr{sup -1}.

A QM/MM Study on the Aqueous Solvation of the Tetrahydroxouranylate [UO?(OH)?]²? Complex Ion  

SciTech Connect

We report a QM augmented QM/MM study on the coordination of the tetrahydroxouranylate ion in aqueous solution. QM/MM geometry optimizations followed by full QM single-point calculations on the optimized structures show that a hexa-coordinated structure is more stable than the hepta-coordinated structure by 43 kJ/mol. Charge transfer of the tetrahydroxouranylate to the solvating water molecules is relatively modest, and can be modeled by including a solvation layer consisting of 12 explicit water molecules.

THE ENVELOPE AND EMBEDDED DISK AROUND THE CLASS 0 PROTOSTAR L1157-mm: DUAL-WAVELENGTH INTERFEROMETRIC OBSERVATIONS AND MODELING  

SciTech Connect

We present dual-wavelength observations and modeling of the nearly edge-on Class 0 young stellar object L1157-mm. Using the Combined Array for Research in Millimeter-wave Astronomy, a nearly spherical structure is seen from the circumstellar envelope at the size scale of 10{sup 2}-10{sup 3} AU in both 1 mm and 3 mm dust emission. Radiative transfer modeling is performed to compare data with theoretical envelope models, including a power-law envelope model and the Terebey-Shu-Cassen model. Bayesian inference is applied for parameter estimation and information criterion is used for model selection. The results prefer the power-law envelope model against the Terebey-Shu-Cassen model. In particular, for the power-law envelope model, a steep density profile with an index of {approx}2 is inferred. Moreover, the dust opacity spectral index {beta} is estimated to be {approx}0.9, implying that grain growth has started at L1157-mm. Also, the unresolved disk component is constrained to be {approx}<40 AU in radius and {approx}<4-25 M{sub Jup} in mass. However, the estimate of the embedded disk component relies on the assumed envelope model.

Progresses in Ab Initio QM/MM Free Energy Simulations of Electrostatic Energies in Proteins: Accelerated QM/MM Studies of pKa, Redox Reactions and Solvation Free Energies  

Science Conference Proceedings (OSTI)

Hybrid quantum mechanical / molecular mechanical (QM/MM) approaches have been used to provide a general scheme for chemical reactions in proteins. However, such approaches still present a major challenge to computational chemists, not only because of the need for very large computer time in order to evaluate the QM energy but also because of the need for propercomputational sampling. This review focuses on the sampling issue in QM/MM evaluations of electrostatic energies in proteins. We chose this example since electrostatic energies play a major role in controlling the function of proteins and are key to the structure-function correlation of biological molecules. Thus, the correct treatment of electrostatics is essential for the accurate simulation of biological systems. Although we will be presenting here different types of QM/MM calculations of electrostatic energies (and related properties), our focus will be on pKa calculations. This reflects the fact that pKa of ionizable groups in proteins provide one of the most direct benchmarks for the accuracy of electrostatic models of macromolecules. While pKa calculations by semimacroscopic models have given reasonable results in many cases, existing attempts to perform pKa calculations using QM/MM-FEP have led to large discrepancies between calculated and experimental values. In this work, we accelerate our QM/MM calculations using an updated mean charge distribution and a classical reference potential. We examine both a surface residue (Asp3) of the bovine pancreatic trypsin inhibitor, as well as a residue buried in a hydrophobic pocket (Lys102) of the T4-lysozyme mutant. We demonstrate that by using this approach, we are able to reproduce the relevant sidechain pKas with an accuracy of 3 kcal/mol. This is well within the 7 kcal/mol energy difference observed in studies of enzymatic catalysis, and is thus sufficient accuracy to determine the main contributions to the catalytic energies of enzymes. We also provide an overall perspective of the potential of QM/MM calculations in general evaluations of electrostatic free energies, pointing out that our approach should provide a very powerful and accurate tool to predict the electrostatics of not only solution but also enzymatic reactions, as well as the solvation free energies of even larger systems, such as nucleic acid bases incorporated into DNA.

Light emission from InGaAs:Bi/GaAs quantum wells at 1.3 {mu}m  

Science Conference Proceedings (OSTI)

Highly strained InGaAs:Bi quantum wells (QWs) were grown on (001)-oriented GaAs substrates by molecular beam epitaxy (MBE). Photoluminescence (PL) reveals strong improvements in the optical properties evidenced by 10 times enhancement in PL intensity and extended emission wavelength up to 1.29 {mu}m when Bi is introduced to InGaAs/GaAs QWs. The improved optical quality results from the Bi surfactant effect as well as the Bi incorporation. Post growth thermal annealing shows that Bi atoms in InGaAs/GaAs QWs do not show good thermal stability at 650 Degree-Sign C and tend to diffuse out of the QWs resulting in large wavelength blue-shifts.

Transformation-optics generalization of tunnelling effects in bi-layers made of paired epsilon-negative/mu-negative media  

E-Print Network (OSTI)

Transformation-media designed by standard transformation-optics (TO) approaches, based on real-valued coordinate-mapping, cannot exhibit single-negative (SNG) character unless such character is already possessed by the domain that is being transformed. In this paper, we show that SNG transformation media can be obtained by transforming a domain featuring double positive (or double-negative) character, via complex analytic continuation of the coordinate transformation rules. Moreover, we apply this concept to the TO-based interpretation of phenomena analogous to the tunnelling effects observable in bilayers made of complementary epsilon-negative (ENG) and mu-negative (MNG) media, and explore their possible TO-inspired extensions and generalizations.

Radiation effects in 1. 06-. mu. m InGaAs LED's and Si photodiodes  

SciTech Connect

Because of the low-intrinsic and radiation-induced attenuation losses in glass fibers in the wavelength range 1.0--1.3 ..mu..m, emitters and detectors operating in this range are of practical importance for radiation-environment applications. We have studied the effects of both ..gamma.. and neutron irradiation on the properties of InGaAs LED's emitting at 1.06 ..mu..m and Si photodiode detectors optimized for this wavelength. While the preirradiation light output of the InGaAs LED's is low relative to many GaAs LED's, the InGaAs devices exhibit less sensitivity to radiation than the most radiation-hardened GaAs LED's. No significant neutron-induced light-output degradation is observed below 1 x 10/sup 13/ n/cm/sup 2/, while 2 x 10/sup 7/ Co-60 rads are required before any ..gamma..-induced degradation is observed. In addition, a significant portion of the ..gamma..-induced light-output degradation can be recovered by applying forward-bias currents of the order of 50 mA in magnitude. Although ..gamma.. irradiation up to 2 x 10/sup 8/ rads has essentially no effect on the photodiodes, neutron fluences above 2 x 10/sup 14/ n/cm/sup 2/ cause a reduction in responsivity. Analysis of the neutron-induced increases in the photodiode leakage current with the guard ring attached reveals a lifetime-damage constant product of 4 x 10/sup -12/ cm/sup 2//n. Laboratory isolators made up of these emitters and detectors have typical preirradiation current-transfer ratios of 5 x 10/sup -4/ which decrease by a factor of 10 after an irradiation of 1.5 x 10/sup 14/ n/cm/sup 2/.

Measurement of the semileptonic charge asymmetry using $B_s^0 \\to D_s \\mu X$ decays  

Science Conference Proceedings (OSTI)

We present a measurement of the time-integrated flavor-specific semileptonic charge asymmetry in the decays of B{sub s}{sup 0} mesons that have undergone flavor mixing, a{sub sl}{sup s}, using B{sub s}{sup 0} ({bar B}{sub s}{sup 0}) {yields} D{sub s}{sup {-+}} {mu}{sup {+-}} X decays, with D{sub s}{sup {-+}} {yields} {phi}{pi}{sup {-+}} and {phi} {yields} K{sup +}K{sup -}, using 10.4 fb{sup -1} of proton-antiproton collisions collected by the D0 detector during Run II at the Fermilab Tevatron Collider. A fit to the difference between the time-integrated D{sub s}{sup -} and D{sub s}{sup +} mass distributions of the B{sub s}{sup 0} and {bar B}{sub s}{sup 0} candidates yields the flavor-specific asymmetry a{sub sl}{sup s} = [-1.08 {+-} 0.72(stat) {+-} 0.17(syst)]% which is the most precise measurement and in agreement with the standard model prediction.

Regenerative amplification of femtosecond pulses: Design and construction of a sub-100fs, {mu}J laser system  

Science Conference Proceedings (OSTI)

Femtosecond lasers are a powerful tool for a wealth of applications in physics, chemistry and biology. In most cases, however, their use is fundamentally restricted to a rather narrow spectral range. This thesis deals with the construction and characterization of a femtosecond light source for spectroscopic applications which overcomes that restriction. It is demonstrated how the output of a continuously pumped Ti:sapphire femtosecond oscillator is amplified to the {mu}J level, while the pulse duration remains below 100fs. A combination of continuous pumping, acousto-optic switching and Ti:Al{sub 2}O{sub 3} as a gain medium allows amplification at high repetition rates. By focusing the high energy pulses into a sapphire crystal, a broad-band continuum can be generated, extended in wavelengths over several hundred nanometers. To accomplish amplification of three orders of magnitude while maintaining the pulse length, a regenerative multipass amplifier system was built. The thesis describes theoretical design, realization and characterization of the system. Theoretical calculations and preliminary measurements were carried out and allow a critical evaluation of the final performance.

First Search for the Standard Model Higgs Boson Using the Semileptonic Decay Channel: H --> WW --> mu bar nu jj  

SciTech Connect

This dissertation presents the first search for the standard model Higgs boson (H) in decay topologies containing a muon, an imbalance in transverse momentum (E{sub T}) and jets, using p{bar p} collisions at {radical}s = 1.96 TeV with an integrated luminosity of 4.3 fb{sup -1} recorded with the D0 detector at the Fermilab Tevatron Collider. This analysis is sensitive primary to contributions from Higgs bosons produced through gluon fusion, with subsequent decay H {yields} WW {yields} {mu}{nu}jj where W represents a real or virtual W boson. In the absence of signal, limits are set at 95% confidence on the production and decay of the standard model Higgs boson for M{sub H} in the range of 115-200 GeV. For M{sub H} = 165 GeV, the observed and expected limits are factors of 11.2 larger than the standard model value. Combining this channel with e{nu}jj final states and including earlier data to increase the integrated luminosity to 5.4 fb{sup -1} produces observed(expected) limits of 5.5(3.8) times the standard model value.

Critical heat flux and boiling heat transfer to water in a 3-mm-diameter horizontal tube.  

DOE Green Energy (OSTI)

Boiling of the coolant in an engine, by design or by circumstance, is limited by the critical heat flux phenomenon. As a first step in providing relevant engine design information, this study experimentally addressed both rate of boiling heat transfer and conditions at the critical point of water in a horizontal tube of 2.98 mm inside diameter and 0.9144 m heated length. Experiments were performed at system pressure of 203 kPa, mass fluxes in range of 50 to 200 kg/m{sup z}s, and inlet temperatures in range of ambient to 80 C. Experimental results and comparisons with predictive correlations are presented.

On Sojourn Times in the $M/M/1$-PS Model, Conditioned on the Number of Other Users  

E-Print Network (OSTI)

We consider the $M/M/1$-PS queue with processor sharing. We study the conditional sojourn time distribution of an arriving customer, conditioned on the number of other customers present. A new formula is obtained for the conditional sojourn time distribution, using a discrete Green's function. This is shown to be equivalent to some classic results of Pollaczeck and Vaulot from 1946. Then various asymptotic limits are studied, including large time and/or large number of customers present, and heavy traffic, where the arrival rate is only slightly less than the service rate.

Structural health and prognostics management for offshore wind turbines : case studies of rotor fault and blade damage with initial O&M cost modeling.  

SciTech Connect

Operations and maintenance costs for offshore wind plants are significantly higher than the current costs for land-based (onshore) wind plants. One way to reduce these costs would be to implement a structural health and prognostic management (SHPM) system as part of a condition based maintenance paradigm with smart load management and utilize a state-based cost model to assess the economics associated with use of the SHPM system. To facilitate the development of such a system a multi-scale modeling approach developed in prior work is used to identify how the underlying physics of the system are affected by the presence of damage and faults, and how these changes manifest themselves in the operational response of a full turbine. This methodology was used to investigate two case studies: (1) the effects of rotor imbalance due to pitch error (aerodynamic imbalance) and mass imbalance and (2) disbond of the shear web; both on a 5-MW offshore wind turbine in the present report. Based on simulations of damage in the turbine model, the operational measurements that demonstrated the highest sensitivity to the damage/faults were the blade tip accelerations and local pitching moments for both imbalance and shear web disbond. The initial cost model provided a great deal of insight into the estimated savings in operations and maintenance costs due to the implementation of an effective SHPM system. The integration of the health monitoring information and O&M cost versus damage/fault severity information provides the initial steps to identify processes to reduce operations and maintenance costs for an offshore wind farm while increasing turbine availability, revenue, and overall profit.

Simultaneous Radio to (Sub-) Mm-Monitoring of Variability and Spectral Shape Evolution of Potential GLAST Blazars  

Science Conference Proceedings (OSTI)

The Large Area Telescope (LAT) instrument onboard GLAST offers a tremendous opportunity for future blazar studies. In order to fully benefit from its capabilities and to maximize the scientific return from the LAT, it is of great importance to conduct dedicated multi-frequency monitoring campaigns that will result comprehensive observations. Consequently, we initiated an effort to conduct a GLAST-dedicated, quasi-simultaneous, broad-band flux-density (and polarization) monitoring of potential GLAST blazars with the Effelsberg and OVRO radio telescopes (11 cm to 7mm wavelength). Here, we present a short overview of these activities which will complement the multi-wavelengths activities of the GLAST/LAT collaboration towards the 'low-energy' radio bands. Further we will give a brief outlook including the extension of this coordinated campaign towards higher frequencies and future scientific aims.

(L{sub e}-L{sub {mu}-}L{sub {tau}}) discrete symmetry for heavy right-handed neutrinos and degenerate leptogenesis  

Science Conference Proceedings (OSTI)

The degenerate leptogenesis is studied when the degeneracy in two of the heavy right-handed neutrinos [the third one is irrelevant if {mu}-{tau} symmetry is assumed] is due to L{identical_to}(L{sub e}-L{sub {mu}-}L{sub {tau}}) discrete symmetry. It is shown that a sizable leptogenesis asymmetry ({epsilon}{>=}10{sup -6}) is possible. The level of degeneracy required also predicts the Majorana phase needed for the asymmetry and this prediction is testable since it is the same phase, which appears in the double {beta} decay. Implications of nonzero reactor angle {theta}{sub 13} are discussed. It is shown that the contribution from sin{sup 2{theta}}{sub 13} to the leptogenesis asymmetry parameter may even dominate. An accurate measurement of sin{sup 2{theta}}{sub 13} would have important implications for the mass degeneracy of heavy right-handed neutrinos.

SEARCH FOR HIGH-MASS RESONANCES DECAYING TO e-mu IN ppbar COLLISIONS AT s**(1/2) = 1.96 TeV  

SciTech Connect

We describe a general search for resonances decaying to a neutral e{mu} final state in p{bar p} collisions at a center-of-mass energy of 1.96 TeV. Using a data sample representing 344 pb{sup -1} of integrated luminosity recorded by the CDF II experiment, we compare Standard Model predictions with the number of observed events for invariant masses between 50 and 800 GeV/c{sup 2}. Finding no significant excess (5 events observed vs. 7.7 {+-} 0.8 expected for M{sub e{mu}} > 100 GeV/c{sup 2}), we set limits on sneutrino and Z' masses as functions of lepton family number violating couplings.

Space charge effect of the high intensity proton beam during the resonance extraction for the Mu2e experiment at Fermilab  

SciTech Connect

The proposed Mu2e experiment to search for direct {mu} {yields} e conversion at Fermilab plans slow, resonant extraction of a beam with 3 x 10{sup 12} protons from the Debuncher ring. Space charge of this high intensity beam is a critical factor, since it induces significant betatron tune spread and consequently affects resonance extraction processes, such as spill uniformity and beam losses. This study shows the multi-particle simulation results in the early stages of resonance extraction and spill uniformity in the presence of 2D and 3D space charge effects. We have presented the results of the third-integer resonance extraction in early stage for the Mu2e experiment in the presence of space charge effects. In order to track particles and to calculate self-consistent space charge effects, Synergia2 was used, which is capable of parallel computing. The space charge tune shift was computed and was reasonable value compared with the analytical calculation. Locations of the septum and Lambertson were chosen so that particles are kicked and extracted efficiently. The spill rates for with and without space charge effects were uniform, but should be improved for the early stage after the sextupole field ramping.

Heat transfer characteristics of R410A-oil mixture flow boiling inside a 7 mm straight smooth tube  

SciTech Connect

Two-phase flow patterns and heat transfer characteristics of R410A-oil mixture flow boiling inside a straight smooth tube with the outside diameter of 7.0 mm were investigated experimentally. The experimental conditions include the evaporation temperature of 5 C, the mass flux from 200 to 400 kg m{sup -2} s{sup -1}, the heat flux from 7.56 to 15.12 kW m{sup -2}, the inlet vapor quality from 0.2 to 0.7, nominal oil concentration from 0% to 5%. The test results show that the heat transfer coefficient of R410A-oil mixture increases with mass flux of refrigerant-oil mixture; the presence of oil enhances the heat transfer at the range of low and intermediate vapor qualities; there is a peak of local heat transfer coefficient at about 2-4% nominal oil concentration at higher vapor qualities, and the peak shifts to lower nominal oil concentration with the increasing of vapor qualities; higher nominal oil concentration gives more detrimental effect at high vapor qualities. The flow pattern map of R410A-oil mixture was developed based on refrigerant-oil mixture properties, and the observed flow patterns match well with the flow pattern map. New correlation to predict the local heat transfer of R410A-oil mixture flow boiling inside the straight smooth tube was developed based on flow patterns and local properties of refrigerant-oil mixture, and it agrees with 90% of the experiment data within the deviation of {+-}25%.

Origins of the extragalactic background at 1mm from a combined analysis of the AzTEC and MAMBO data in GOODS-N  

E-Print Network (OSTI)

We present a study of the cosmic infrared background, which is a measure of the dust obscured activity in all galaxies in the Universe. We venture to isolate the galaxies responsible for the background at 1mm; with spectroscopic and photometric redshifts we constrain the redshift distribution of these galaxies. We create a deep 1.16mm map (sigma ~ 0.5mJy) by combining the AzTEC 1.1mm and MAMBO 1.2mm datasets in GOODS-N. This combined map contains 41 secure detections, 13 of which are new. By averaging the 1.16mm flux densities of individually undetected galaxies with 24um flux densities > 25uJy, we resolve 31--45 per cent of the 1.16mm background. Repeating our analysis on the SCUBA 850um map, we resolve a higher percentage (40--64 per cent) of the 850um background. A majority of the background resolved (attributed to individual galaxies) at both wavelengths comes from galaxies at z > 1.3. If the ratio of the resolved submillimeter to millimeter background is applied to a reasonable scenario for the origins o...

On the nonexistence of $[\\binom{2m}{m-1}, 2m, \\binom{2m-1}{m-1}]$, $m$ odd, complex orthogonal design  

E-Print Network (OSTI)

Complex orthogonal designs (CODs) are used to construct space-time block codes. COD $\\mathcal{O}_z$ with parameter $[p, n, k]$ is a $p\\times n$ matrix, where nonzero entries are filled by $\\pm z_i$ or $\\pm z^*_i$, $i = 1, 2,..., k$, such that $\\mathcal{O}^H_z \\mathcal{O}_z = (|z_1|^2+|z_2|^2+...+|z_k|^2)I_{n \\times n}$. Adams et al. in "The final case of the decoding delay problem for maximum rate complex orthogonal designs," IEEE Trans. Inf. Theory, vol. 56, no. 1, pp. 103-122, Jan. 2010, first proved the nonexistence of $[\\binom{2m}{m-1}, 2m, \\binom{2m-1}{m-1}]$, $m$ odd, COD. Combining with the previous result that decoding delay should be an integer multiple of $\\binom{2m}{m-1}$, they solved the final case $n \\equiv 2 \\pmod 4$ of the decoding delay problem for maximum rate complex orthogonal designs. In this paper, we give another proof of the nonexistence of COD with parameter $[\\binom{2m}{m-1}, 2m, \\binom{2m-1}{m-1}]$, $m$ odd. Our new proof is based on the uniqueness of $[\\binom{2m}{m-1}, 2m-1, \\binom{...

A self-consistent MoD-WM/MM structural refinement method: characterization of hydrogen bonding in the orytricha nova G-1uar  

DOE Green Energy (OSTI)

This paper generalizes the MoD-QM/MM hybrid method, developed for ab initio computations of protein electrostatic potentials [Gasc6n, l.A.; Leung, S.S.F.; Batista, E.R.; Batista, V.S. J. Chem. Theory Comput. 2006,2, 175-186], as a practical algorithm for structural refinement of extended systems. The computational protocol involves a space-domain decomposition scheme for the formal fragmentation of extended systems into smaller, partially overlapping, molecular domains and the iterative self-consistent energy minimization of the constituent domains by relaxation of their geometry and electronic structure. The method accounts for mutual polarization of the molecular domains, modeled as Quantum-Mechanical (QM) layers embedded in the otherwise classical Molecular-Mechanics (MM) environment according to QM/MM hybrid methods. The method is applied to the description of benchmark models systems that allow for direct comparisons with full QM calculations, and subsequently applied to the structural characterization of the DNA Oxytricha nova Guanine quadruplex (G4). The resulting MoD-QM/MM structural model of the DNA G4 is compared to recently reported highresolution X-ray diffraction and NMR models, and partially validated by direct comparisons between {sup 1}H NMR chemical shifts that are highly sensitive to hydrogen-bonding and stacking interactions and the corresponding theoretical values obtained at the density functional theory DFT QM/MM (BH&H/6-31 G*:Amber) level in conjunction with the gauge independent atomic orbital (GIAO) method for the ab initio self consistent-field (SCF) calculation of NMR chemical shifts.

Above room-temperature operation of InAs/AlGaSb superlattice quantum cascade lasers emitting at 12 {mu}m  

SciTech Connect

The authors report on above-room-temperature operation of InAs/AlGaSb quantum cascade lasers emitting at 12 {mu}m. The laser structures are grown on a n-InAs (100) substrate using solid-source molecular beam epitaxy. An InAs/AlGaSb superlattice is used as an active part and an InAs double plasmon waveguide is used for optical confinement. Results show that increased doping concentration in the injection part of the active region expands the current operation range of the devices, allowing laser operation at and above room temperature. The observed threshold current density is 4.0 kA/cm{sup 2} at 300 K; the maximum operation temperature is 340 K.

Background Study on nu_e Appearance from a nu_mu Beam in Very Long Baseline Neutrino Oscillation Experiments with a Large Water Cherenkov Detector

Broadening and shifting of the methanol 119 {mu}m gain line of linear and circular polarization by collision with chiral molecules  

Science Conference Proceedings (OSTI)

Evidence of circular dichroism has been observed in the spectral properties of a gas of left-right symmetric molecules. This dichroism comes about as the result of collisions of the symmetric molecules with left-right asymmetric molecules introduced as a buffer gas. In this sense, the dichroism can be said to have been transferred from the chiral buffer molecules to the symmetric, non-chiral molecules of the background vapor. This transferred dichroism appears as broadening in the gain line of the symmetric molecule which is asymmetric with respect to the right or left handedness of a circularly polarized probe. The broadening of the 119 {mu}m line of the methanol molecule was observed using infrared-far infrared double resonance spectroscopy.

Regenerative amplification of picosecond 10-{mu}m pulses in a high-pressure optically pumped CO{sub 2} laser  

Science Conference Proceedings (OSTI)

A model is developed and numerical calculations are performed for the regenerative amplification of seed picosecond 10-{mu}m radiation pulses in a high-pressure optically pumped CO{sub 2} laser. It is established that by varying the cavity parameters, the conditions of efficient regenerative amplification may be optimised for the case of a relatively short-duration (50 ns) solid-state Cr:Er:YSGG laser and 'long-duration' (250 ns) electrodischarge chemical HF laser. It is shown that the schemes of a CO{sub 2} amplifier with optical pumping presented allow obtaining the pulses with the duration of 3ps, output energy of 1-5 mJ, and peak power of {approx}1 GW at the pump energy of 150-200 mJ.

Leading order hadronic contributions to a{sub {mu}} and {alpha}{sub QED} from N{sub f} = 2 + 1 + 1 twisted mass fermions  

Science Conference Proceedings (OSTI)

We present the first four-flavour lattice calculation of the leading-order hadronic vacuum polarisation contribution to the anomalous magnetic moment of the muon, a{sub {mu}}{sup hvp}, and the hadronic running of the QED coupling constant, {Delta}{alpha}{sup hvp}{sub QED}(Q{sup 2}). In the heavy sector a mixed-action setup is employed. The bare quark masses are determined from matching the K- and D-meson masses to their physical values. Several light quark masses are used in order to yield a controlled extrapolation to the physical pion mass by utilising a recently proposed improved method. We demonstrate that this method also works in the four-flavour case.

Compositional dependence of the 1.8 {mu}m emission properties of Tm{sup 3+} ions in silicate glass  

Science Conference Proceedings (OSTI)

The compositional dependence of the 1.8 {mu}m emission properties of Tm{sup 3+} ion-doped lead silicate glasses is investigated. Judd-Ofelt parameters are calculated and their variation with different glass modifier ions is obtained. The Judd-Ofelt parameters increase with decreased modifier ionic radius. A large spontaneous emission probability and a large emission cross-section are found to be related with the strength of the modifier ion. Fluorescence spectra are analyzed using rate equations and compared with recorded data. The results are very close, indicating the reliability of this method. Non-radiative probability is deduced by fitting the fluorescence decay curve; it becomes smaller with increased ionic field strength. Energy transfer processes are studied using the extended overlap integral method.

Empirical Investigation on the Impact of Hydrogen Collisions for the Formation of CI 1.07 mu~m Lines Based on the Solar Center-to-Limb Variation  

E-Print Network (OSTI)

With an aim of examining the validity of non-LTE line-formation calculations for the strong C I lines of multiplet 1 at 1.068-1.069 mu~m, especially in terms of the treatment of collisions with neutral hydrogen (H I) atoms, we computed theoretical equivalent widths (W_lambda) of these lines corresponding to specific intensities of different angles (mu = cos(theta)) on the solar disk under various conditions, which were then compared with the empirical W_lambda vs. mu relations obtained from our spectroscopic observations using the Domeless Solar Telescope at Hida Observatory. It turned out that our observational data are almost consistent with the theoretical simulations done with the H I collision rates computed with the classical formula, which suggests that the necessity of its significant revision (e.g., considerable reduction) is unlikely.

Investigation of surface inhomogeneity and estimation of the GOES skin temperature assimilation errors of the MM5 implied by the inhomogeneity over Houston metropolitan area  

E-Print Network (OSTI)

This study developed a parameterization method to investigate the impacts of inhomogeneous land surfaces on mesoscale model simulations using a high-resolution 1-d PBL model. Then, the 1-d PBL model was used to investigate the inhomogeneity-caused model errors in applying the GOES satellite skin temperature assimilation technique into the MM5 over the Houston metropolitan area (HOU). In order to investigate the surface inhomogeneity impacts on the surface fluxes and PBL variables over HOU, homo- and inhomogeneous 1-d PBL model simulations were performed over HOU and compared to each other. The 1-d PBL model was constructed so that the surface inhomogeneities were able to be represented within model grid elements using a methodology similar to Avissar and Pielke (1989). The surface inhomogeneities over HOU were defined using 30-m resolution land cover data produced by Global Environment Management (GEM), Inc. The inhomogeneity parameterization method developed in the 1-d model was applied to a standard MM5 simulation to test the applicability of the parameterization to 3-d mesoscale model simulations. From the 1-d simulations it was inferred that the surface inhomogeneities would enhance the sensible heat flux by about 36 % and reduce the latent heat flux by about 25 %, thereby inducing the warmer (0.7 %) and drier (-1.0 %) PBL and the colder and moister PBL top induced by greater turbulent diffusivities. The 3-d application of the inhomogeneity parameterization indicated consistent results with the 1-d in general, with additional effects of advection and differential local circulation. The original GOES simulation was warmer compared to observations over HOU than over surrounding areas. The satellite data assimilation itself would lead to a warm bias due to erroneous estimation of gridpoint-mean skin temperature by the satellite, but 1-d simulations indicate that the impact of this error should be much weaker than what was observed. It seems that, unless the already existing warm and dry bias of the MM5 is corrected, the inhomogeneity parameterization in the MM5 would adversely affect the MM5 performance. Therefore, consideration of the surface inhomogeneities in the urban area needs to be confined to the GOES skin temperature retrieval errors at the moment.

ADAPTIVE OPTICS OBSERVATIONS OF 3 {mu}m WATER ICE IN SILHOUETTE DISKS IN THE ORION NEBULA CLUSTER AND M43  

Science Conference Proceedings (OSTI)

We present the near-infrared images and spectra of four silhouette disks in the Orion Nebula Cluster (M42) and M43 using the Subaru Adaptive Optics system. While d053-717 and d141-1952 show no water ice feature at 3.1 {mu}m, a moderately deep ({tau}{sub ice} {approx} 0.7) water ice absorption is detected toward d132-1832 and d216-0939. Taking into account the water ice so far detected in the silhouette disks, the critical inclination angle to produce a water ice absorption feature is confirmed to be 65 Degree-Sign -75 Degree-Sign . As for d216-0939, the crystallized water ice profile is exactly the same as in the previous observations taken 3.63 years ago. If the water ice material is located at 30 AU, then the observations suggest it is uniform at a scale of about 3.5 AU.

Selection Tests of MnZn and NiZn Ferrites for Mu2e 300 kHz and 5.1 MHz AC Dipoles  

SciTech Connect

Mu2e, a charged lepton flavor violation (CLFV) experiment is planned to start at Fermilab late in this decade. The proposed experiment will search for neutrinoless muon to electron conversions with unprecedented sensitivity, better than 6 x 10{sup -17 }at 90% CL. To achieve this sensitivity the incoming proton beam must be highly suppressed during the window for detecting the muon decays. The current proposal for beam extinction is based on a collimator design with two dipoles running at {approx}300 kHz and 5.1 MHz and synchronized to the proton bunch spacing. The appropriate choice of ferrite material for the magnet yoke is a critical step in the overall design of the dipoles and their reliable operation at such high frequencies over the life of the experiment. This choice, based on a series of the thermal and magnetic measurements of the ferrite samples, is discussed in the paper. Additionally, the first results from the testing at 300 kHz of a prototype AC dipole are presented.

Proton form factor ratio, {mu}{sub p}G{sub E}{sup P}/G{sub M}{sup P} from double spin asymmetry  

Science Conference Proceedings (OSTI)

The form factors are fundamental properties of the nucleon representing the effect of its structure on its response to electromagnetic probes such as electrons. They are functions of the four-momentum transfer squared Q{sup 2} between the electron and the proton. This thesis reports the results of a new measurement of the ratio of the electric and magnetic form factors of the proton up to Q{sup 2} = 5.66 (GeV/c){sup 2} using the double spin asymmetry with a polarized beam and target. Experiment E07-003 (SANE, Spin Asymmetries of the Nucleon Experiment) was carried out in Hall C at Jefferson Lab in 2009 to study the proton spin structure functions with a dynamically polarized ammonia target and longitudinally polarized electron beam. By detecting elastically scattered protons in the High-Momentum Spectrometer (HMS) in coincidence with the electrons in the Big Electron Telescope Array (BETA), elastic measurements were carried out in parallel. The elastic double spin asymmetry allows one to extract the proton electric to magnetic form factor ratio G{sup p}{sub E}/G{sup p}{sub M} at high-momentum transfer, Q{sup 2} = 5.66 (GeV/c){sup 2}. In addition to the coincidence data, inclusively scattered electrons from the polarized ammonia target were detected by HMS, which allows to measure the beam-target asymmetry in the elastic region with the target spin nearly perpendicular to the momentum transfer, and to extract G{sup p}{sub E}/G{sup p}{sub M} at low Q{sup 2} = 2.06 (GeV/c){sup 2}. This alternative measurement of G{sup p}{sub E}/G{sup p}{sub M} has verified and confirmed the dramatic discrepancy at high Q{sup 2} between the Rosenbluth and the recoil-polarization-transfer iv method with a different measurement technique and systematic uncertainties uncorrelated to those of the recoil-polarization measurements. The measurement of the form factor ratio at Q{sup 2} = 2.06 (GeV/c){sup 2} has been determined as {mu}{sub p}G{sup p}{sub E}/G{sup p}{sub M} = 0.605{+-}0.178{sub stat}{+-}0.033{sub sys} which is in agreement with an earlier measurement with the polarized target technique at similar kinematics. The measurement of the form factor ratio at Q{sup 2} = 5.66 (GeV/c){sup 2} has been determined as {mu}{sub p}G{sup p}{sub E}/G{sup p}{sub M} = 0.672 {+-} 0.362{sub stat} which represents the highest Q{sup 2} reach with the double spin asymmetry to date.

QM/MM Lineshape Simulation of the Hydrogen-bonded Uracil NH Stretching Vibration of the Adenine:Uracil Base Pair in CDCl$_3$  

E-Print Network (OSTI)

A hybrid Car-Parrinello QM/MM molecular dynamics simulation has been carried out for the Watson-Crick base pair of 9-ethyl-8-phenyladenine and 1-cyclohexyluracil in deuterochloroform solution at room temperature. The resulting trajectory is analyzed putting emphasis on the N-H$...$N Hydrogen bond geometry. Using an empirical correlation between the $\\NN$-distance and the fundamental NH-stretching frequency, the time-dependence of this energy gap along the trajectory is obtained. From the gap-correlation function we determine the infrared absorption spectrum using lineshape theory in combination with a multimode oscillator model. The obtained average transition frequency and the width of the spectrum is in reasonable agreement with recent experimental data.

Evaluating the influence of antecedent soil moisture on variability of the North American Monsoon precipitation in the coupled MM5/VIC modeling system  

SciTech Connect

The influence of antecedent soil moisture on North American monsoon system (NAMS) precipitation variability was explored using the MM5 mesoscale model coupled with the Variable Infiltration Capacity (VIC) land surface model. Sensitivity experiments were performed with extreme wet and dry initial soil moisture conditions for both the 1984 wet monsoon year and the 1989 dry year. The MM5-VIC model reproduced the key features of NAMS in 1984 and 1989 especially over northwestern Mexico. Our modeling results indicate that the land surface has memory of the initial soil wetness prescribed at the onset of the monsoon that persists over most of the region well into the monsoon season (e.g. until August). However, in contrast to the classical thermal contrast concept, where wetter soils lead to cooler surface temperatures, less land-sea thermal contrast, weaker monsoon circulations and less precipitation, the coupled model consistently demonstrated a positive soil moisture – precipitation feedback. Specifically, anomalously wet premonsoon soil moisture always lead to enhanced monsoon precipitation, and the reverse was also true. The surface temperature changes induced by differences in surface energy flux partitioning associated with pre-monsoon soil moisture anomalies changed the surface pressure and consequently the flow field in the coupled model, which in turn changed moisture convergence and, accordingly, precipitation patterns. Both the largescale circulation change and local land-atmospheric interactions in response to premonsoon soil moisture anomalies play important roles in the coupled model’s positive soil moisture monsoon precipitation feedback. However, the former may be sensitive to the strength and location of the thermal anomalies, thus leaving open the possibility of both positive and negative soil moisture precipitation feedbacks.

2.8 {mu}m emission from type-I quantum wells grown on InAs{sub x}P{sub 1-x}/InP metamorphic graded buffers  

Science Conference Proceedings (OSTI)

We report 2.8 {mu}m emission from compressively strained type-I quantum wells (QWs) grown on InP-based metamorphic InAs{sub x}P{sub 1-x} step-graded buffers. High quality metamorphic graded buffers showed smooth surface morphology and low threading dislocation densities of approximately 2.5 Multiplication-Sign 10{sup 6} cm{sup -2}. High-resolution x-ray diffraction scans showed strong satellites from multiple quantum wells grown on metamorphic buffers, and cross-sectional transmission electron microscopy revealed smooth and coherent quantum well interfaces. Room-temperature photoluminescence emission at 2.8 {mu}m with a narrow linewidth ({approx}50 meV) shows the promise of metamorphic growth for mid-infrared laser diodes on InP.

The Ability of MM5 to Simulate Ice Clouds: Systematic Comparison between Simulated and Measured Fluxes and Lidar/Radar Profiles at SIRTA Atmospheric Observatory  

SciTech Connect

Ice clouds play a major role in the radiative energy budget of the Earth-atmosphere system (Liou 1986). Their radiative effect is governed primarily by the equilibrium between their albedo and greenhouse effects. Both macrophysical and microphysical properties of ice clouds regulate this equilibrium. For quantifying the effect of these clouds onto climate and weather systems, they must be properly characterized in atmospheric models. In this paper we use remote-sensing measurements from the SIRTA ground based atmospheric observatory (Site Instrumental de Recherche par Teledetection Atmospherique, http://sirta.lmd.polytechnique.fr). Lidar and radar observations taken over 18 months are used, in order to gain statistical confidence in the model evaluation. Along this period of time, 62 days are selected for study because they contain parts of ice clouds. We use the ''model to observations'' approach by simulating lidar and radar signals from MM5 outputs. Other more classical variables such as shortwave and longwave radiative fluxes are also used. Four microphysical schemes, among which that proposed by Reisner et al. (1998) with original or modified parameterizations of particle terminal fall velocities (Zurovac-Jevtic and Zhang 2003, Heymsfield and Donner 1990), and the simplified Dudhia (1989) scheme are evaluated in this study.

The sensitivity of the PSU-NCAR model (MM5) to cumulus parameterization in simulating the mesoscale environment associated with 2 June 1995 West Texas tornado outbreak  

E-Print Network (OSTI)

On 2 June 1995, many supercede thunderstorms were graphics. observed in West Texas between Lubbock and Amarillo under the synoptic and mesoscale environment which was increasingly more supportive of severe convection. Of the storms, those which crossed a particular outflow boundary, generated by earlier convection, produced violent tornadoes near Friona and Dimmitt, Texas. As documented in numerous other studies, the outflow boundary generated from the earlier convection seemed to play a important role in producing tornadic supercedes. This study presents observational features of the event, performs model simulations with three disparate cumulus parameterization schemes, and does a careful comparison between the simulations and observations. This study tries to understand the sequence of events which preceded the severe storm outbreak. Particularly, mesoscale features such as the dry line and outflow boundaries are carefully documented. Because of the significant impact of the convective outflow boundaries, this study tries to examine the sensitivity of the PSU/NCAR three dimensional nonhydrostatic mesoscale model (MM5) to the choice of cumulus parameterization scheme. The schemes used in this study include Kain-Fritsch, Fritsch-Chappell, and Grell schemes. The model simulation has a 67 x 67 grid domain centered at 35[] N and 102[] W with 27 km grid spacing, and starts at 12 UTC 2 June for 12-h forecast. The simulation results showed that, even though the general features agreed well among the three different simulations, the mesoscale features such as the outflow boundary, convective rain, temperature gradient, and pressure gradient associated with tee convective outflow were somewhat different among the different cumulus parameterizations. It seemed that the different behavior of the simulations was strongly dependent on the components constructing each cumulus parameterization. Despite the limitation of evidence suggested in this study, the Kain-Fritsch scheme appeared to be most suitable for the simulation of meso-[] scale features.

Quantum mechanical/molecular mechanical (QM/MM) free energy simulations are applied for understanding the mechanism of the acylation reaction catalyzed by sedolisin, a representative serine-carboxyl peptidase, leading to the acyl-enzyme (AE) and first product from the enzyme-catalyzed reaction. One of the interesting questions to be addressed in this work is the origin of the substrate specificity of sedolisin that shows a relatively high activity on the substrates with Glu at P1 site. It is shown that the bond making and breaking events of the acylation reaction involving a peptide substrate (LLE*FL) seem to be accompanied by local conformational changes, proton transfers as well as the formation of alternative hydrogen bonds. The results of the simulations indicate that the conformational change of Glu at P1 site and its formation of a low barrier hydrogen bond with Asp-170 (along with the transient proton transfer) during the acylation reaction might play a role in the relatively high specificity for the substrate with Glu at P1 site. The role of some key residues in the catalysis is confirmed through free energy simulations. Glu-80 is found to act as a general base to accept a proton from Ser-287 during the nucleophilic attack and then as a general acid to protonate the leaving group (N H of P1 -Phe) during the cleavage of the scissile peptide bond. Another acidic residue, Asp-170, acts as a general acid catalyst to protonate the carbonyl of P1-Glu during the formation of the tetrahedral intermediate and as a general base for the formation of the acyl-enzyme. The energetic results from the free energy simulations support the importance of proton transfer from Asp-170 to the carbonyl of P1-Glu in the stabilization of the tetrahedral intermediate and the formation of a low-barrier hydrogen bond between the carboxyl group of P1-Glu and Asp-170 in the lowering of the free energy barrier for the cleavage of the peptide bond. Detailed analyses of the proton transfers during acylation are also given.

Study of B_s Mixing at the D-Zero Detector at Fermilab Using the Semi-leptonic Decay B_s -> D_s mu nu X  

SciTech Connect

B{sub s}{sup 0} mixing studies provide a precision test of Charge-Parity violation in the Standard Model. A measurement of {Delta}m{sub s} constrains elements of the CKM quark rotation matrix [1], providing a probe of Standard Model Charge-Parity violation. This thesis describes a study of B{sub s}{sup 0} mixing in the semileptonic decay B{sub s}{sup 0} {yields} D{sub s}{sup -} {mu}{sup +}{nu}X, where D{sub s}{sup -} {yields} {phi}{pi}{sup -}, using data collected at the D-Zero detector at Fermi National Accelerator in Batavia, Illinois. Approximately 2.8 fb{sup -1} of data collected between April 2002 and August 2007 was used, covering the entirety of the Tevatron's RunIIa (April 2002 to March 2006) and part of RunIIb (March 2006-August 2007). Taggers using both opposite-side and same-side information were used to obtain the flavor information of the B{sub s}{sup 0} meson at production. The charge of the muon in the decay B{sub s}{sup 0} {yields} D{sub s}{sup -}{mu}{sup +}{nu}X was used to determine the flavor of the B{sub s}{sup 0} at decay. The B{sub d}{sup 0} mixing frequency, {Delta}m{sub d}, was measured to verify the analysis procedure. A log-likelihood calculation was performed, and a measurement of {Delta}m{sub s} was obtained. The final result was {Delta}m{sub s} = 18.86 {+-} 0.80(stat.) {+-} 0.37(sys.) with a significance of 2.6{sigma}.

THE SOLAR NEIGHBORHOOD. XXVII. DISCOVERY OF NEW PROPER MOTION STARS WITH {mu} {>=} 0.''18 yr{sup -1} IN THE SOUTHERN SKY WITH 16.5 < R{sub 59F} {<=} 18.0  

SciTech Connect

Here we present 1584 new southern proper motion systems with {mu} {>=} 0.''18 yr{sup -1} and 16.5 > R{sub 59F} {>=} 18.0. This search complements the six previous SuperCOSMOS-RECONS (SCR) proper motion searches of the southern sky for stars within the same proper motion range, but with R{sub 59F} {<=} 16.5. As in previous papers, we present distance estimates for these systems and find that three systems are estimated to be within 25 pc, including one, SCR 1546-5534, possibly within the RECONS 10 pc horizon at 6.7 pc, making it the second nearest discovery of the searches. We find 97 white dwarf candidates with distance estimates between 10 and 120 pc, as well as 557 cool subdwarf candidates. The subdwarfs found in this paper make up nearly half of the subdwarf systems reported from our SCR searches and are significantly redder than those discovered thus far. The SCR searches have now found 155 red dwarfs estimated to be within 25 pc, including 10 within 10 pc. In addition, 143 white dwarf candidates and 1155 cool subdwarf candidates have been discovered. The 1584 systems reported here augment the sample of 4724 systems previously discovered in our SCR searches and imply that additional systems fainter than R{sub 59F} = 18.0 are yet to be discovered.

UCAC3 PROPER MOTION SURVEY. I. DISCOVERY OF NEW PROPER MOTION STARS IN UCAC3 WITH 0.''40 yr{sup -1} > {mu} {>=} 0.''18 yr{sup -1} BETWEEN DECLINATIONS -90{sup 0} AND -47{sup 0}  

Science Conference Proceedings (OSTI)

This paper presents 442 new proper motion stellar systems in the southern sky between declinations -90{sup 0} and -47{sup 0} with 0.''40 yr{sup -1} > {mu} {>=} 0.''18 yr{sup -1}. These systems constitute a 25.3% increase in new systems for the same region of the sky covered by previous SuperCOSMOS RECONS (SCR) searches that used Schmidt plates as the primary source of discovery. Among the new systems are 25 multiples, plus an additional 7 new common proper motion (CPM) companions to previously known primaries. All stars have been discovered using the third U.S. Naval Observatory (USNO) CCD Astrograph Catalog (UCAC3). A comparison of the UCAC3 proper motions to those from the Hipparcos, Tycho-2, Southern Proper Motion (SPM4), and SuperCOSMOS efforts is presented and shows that UCAC3 provides similar values and precision to the first three surveys. The comparison between UCAC3 and SuperCOSMOS indicates that proper motions in R.A. are systematically shifted in the SuperCOSMOS data but are consistent in decl. data, while overall showing a significantly higher scatter. Distance estimates are derived for stars having SuperCOSMOS Sky Survey B{sub J} , R{sub 59F}, and I{sub IVN} plate magnitudes and Two-Micron All Sky Survey infrared photometry. We find 15 systems estimated to be within 25 pc, including UPM 1710-5300 our closest new discovery estimated at 13.5 pc. Such new discoveries suggest that more nearby stars are yet to be found in these slower proper motion regimes, indicating that more work is needed to develop a complete map of the solar neighborhood.

Experiments with energetic {mu}d and {mu}t emitted from solid hydrogen  

DOE Green Energy (OSTI)

A set of experiments is reviewed which makes use of the emission of muonic deuterium from the surface of a layer of solid hydrogen. The behavior of muons in a solid target system has been studied via detection of muon decay electrons, muonic x-rays, and fusion products (neutrons and charged particles). The emission of muonic deuterium is understood to result from the Ramsauer-Townsend scattering minimum. The energy distribution of the emitted atoms ranges from tenths of eV to about 10eV, and can be controlled to some extent. A proposal is described to use muonic tritium emission to measure the energy dependence of muonic molecular formation.

Procyon: 18-MJ, 2-{mu}s pulsed power system  

SciTech Connect

The Procyon high explosive pulsed power (HEPP) system was designed to drive plasma z-pinch experiments that produce Megajoule soft x-ray pulses when the plasma stagnates on axis. In the proceedings of the Ninth IEEE Pulsed Power Conference, we published results from system development tests. At this time, we have fielded seven tests in which the focus was on either vacuum switching or load physics. Four of the tests concentrated on the performance of a Plasma Flow Switch (PFS) which employed a 1/r mass distribution in the PFS barrel. Of the four tests, two had dummy loads and one had an implosion load. In addition, one of the tests broke down near the vacuum dielectric interface, and the result demonstrated what Procyon could deliver to an 18 nH load. We will summarize PFS results and the 18 nH test which is pertinent to upcoming solid/liquid liner experiments. On our other three tests, we eliminated the PFS switching and powered the z-pinch directly with the HEPP system. From the best of these direct drive tests we obtained 1.5 MJ of radiation in a 250 ns pulse, our best radiation pulse to date. We will also summarize direct drive test results. More details are given in other papers in this conference for both the PFS and direct drive experiments, and an updated analysis of our opening switch performed is also included. The remainder of this paper describes the parameters and capabilities of our system, and we will use the data from several experiments to provide more precise information than previously available.

Plasma-enhanced and thermal atomic layer deposition of Al{sub 2}O{sub 3} using dimethylaluminum isopropoxide, [Al(CH{sub 3}){sub 2}({mu}-O{sup i}Pr)]{sub 2}, as an alternative aluminum precursor  

Science Conference Proceedings (OSTI)

The authors have been investigating the use of [Al(CH{sub 3}){sub 2}({mu}-O{sup i}Pr)]{sub 2} (DMAI) as an alternative Al precursor to [Al(CH{sub 3}){sub 3}] (TMA) for remote plasma-enhanced and thermal ALD over wide temperature ranges of 25-400 and 100-400 deg. C, respectively. The growth per cycle (GPC) obtained using in situ spectroscopic ellipsometry for plasma-enhanced ALD was 0.7-0.9 A/cycle, generally lower than the >0.9 A/cycle afforded by TMA. In contrast, the thermal process gave a higher GPC than TMA above 250 deg. C, but below this temperature, the GPC decreased rapidly with decreasing temperature. Quadrupole mass spectrometry data confirmed that both CH{sub 4} and HO{sup i}Pr were formed during the DMAI dose for both the plasma-enhanced and thermal processes. CH{sub 4} and HO{sup i}Pr were also formed during the H{sub 2}O dose but combustion-like products (CO{sub 2} and H{sub 2}O) were observed during the O{sub 2} plasma dose. Rutherford backscattering spectrometry showed that, for temperatures >100 deg. C and >200 deg. C for plasma-enhanced and thermal ALD, respectively, films from DMAI had an O/Al ratio of 1.5-1.6, a H content of {approx}5 at. % and mass densities of 2.7-3.0 g cm{sup -3}. The film compositions afforded from DMAI were comparable to those from TMA at deposition temperatures {>=}150 deg. C At lower temperatures, there were differences in O, H, and C incorporation. 30 nm thick Al{sub 2}O{sub 3} films from the plasma-enhanced ALD of DMAI were found to passivate n- and p-type Si floatzone wafers ({approx}3.5 and {approx}2 {Omega} cm, respectively) with effective carrier lifetimes comparable to those obtained using TMA. Surface recombination velocities of < 3 and < 6 cm s{sup -1} were obtained for the n- and p-type Si, respectively. Using these results, the film properties obtained using DMAI and TMA are compared and the mechanisms for the plasma-enhanced and thermal ALD using DMAI are discussed.

Obtaining and Ensuring Persistence of O&M Savings Through Resource Conservation Management  

E-Print Network (OSTI)

Resource conservation management is a management program similar to financial management in that its success requires commitment by all levels of the organization to the process as well as an accounting procedure and auditing of critical components. Resource conservation management provides a framework for all elements of efficient building operations and maintenance. The savings connected with the program are principally connected with changes in the way buildings are operated and maintained. This paper discusses the evolution of the resource conservation management service and the savings associated with the two-year pilot effort with seven school districts as well as the critical components of a successful program. The hope is that top-management will recognize the value of resource conservation management in keeping their overhead costs under control and will incorporate it into the management structure of their jurisdiction or firm.

Duck Valley Reservoirs Fish Stocking and O&M, Annual Progress Report 2007-2008.  

DOE Green Energy (OSTI)

The Duck Valley Reservoirs Fish Stocking and Operations and Maintenance Project (DV Fisheries) is an ongoing resident fish program that serves to partially mitigate the loss of anadromous fish that resulted from downstream construction of the federal hydropower system. The project's goals are to enhance subsistence fishing and educational opportunities for Tribal members of the Shoshone-Paiute Tribes and provide fishing opportunities for non-Tribal members. In addition to stocking rainbow trout (Oncorhynchus mykiss) in Mountain View (MVR), Lake Billy Shaw (LBS), and Sheep Creek Reservoirs (SCR), the program is also designed to: maintain healthy aquatic conditions for fish growth and survival, provide superior facilities with wilderness qualities to attract non-Tribal angler use, and offer clear, consistent communication with the Tribal community about this project as well as outreach and education within the region and the local community. Tasks for this performance period fall into three categories: operations and maintenance, monitoring and evaluation, and public outreach. Operation and maintenance of the three reservoirs include maintaining fences, roads, dams and all reservoir structures, feeder canals, water troughs, stock ponds, educational signs, vehicles, equipment, and restroom facilities. Monitoring and evaluation activities include creel, gillnet, wildlife, and bird surveys, water quality and reservoir structures monitoring, native vegetation planting, photo point documentation, and control of encroaching exotic vegetation. Public outreach activities include providing environmental education to school children, providing fishing reports to local newspapers and vendors, updating the website, hosting community environmental events, and fielding numerous phone calls from anglers. The reservoir monitoring program focuses on water quality and fishery success. Sheep Creek Reservoir and Lake Billy Shaw had less than productive trout growth due to water quality issues including dissolved oxygen and/or turbidity. Regardless, angler fishing experience was the highest at Lake Billy Shaw. Trout in Mountain View Reservoir were in the best condition of the three reservoirs and anglers reported very good fishing there. Water quality (specifically dissolved oxygen and temperature) remain the main limiting factors in the fisheries, particularly in late August to early September.

Injection-locked composite lasers for mm-wave modulation : LDRD 117819 final report.  

Science Conference Proceedings (OSTI)

This report summarizes a 3-year LDRD program at Sandia National Laboratories exploring mutual injection locking of composite-cavity lasers for enhanced modulation responses. The program focused on developing a fundamental understanding of the frequency enhancement previously demonstrated for optically injection locked lasers. This was then applied to the development of a theoretical description of strongly coupled laser microsystems. This understanding was validated experimentally with a novel 'photonic lab bench on a chip'.

Particle Image Velocimetry Measurements and Analysis of Bypass Data for a Scaled 6mm Gap  

SciTech Connect

The purpose of the fluid dynamics experiments in the MIR (Matched Index of-Refraction) flow system at Idaho National Laboratory (INL) is to develop benchmark databases for the assessment of Computational Fluid Dynamics (CFD) solutions of the momentum equations, scalar mixing, and turbulence models for the flow ratios between coolant channels and bypass gaps in the interstitial regions of typical prismatic standard fuel element (SFE) or upper reflector block geometries of typical Modular High-temperature Gas-cooled Reactors (MHTGR) in the limiting case of negligible buoyancy and constant fluid properties. The experiments will use optical techniques, primarily particle image velocimetry (PIV) in the INL Matched Index of Refraction (MIR) flow system.

Tau-Mu Flavor Violation and the Scale of New Physics 1  

E-Print Network (OSTI)

Abstract. Motivated by the strong experimental evidence of large ?µ ??? neutrino oscillations, we study existing constraints for related µ ? ? flavor violation. Using a general bottom-up approach, we construct dimension-6 effective fermionic operators whose coefficients encode the scale of new physics associated with µ ?? flavor violation, which is a piece in the puzzle of the origin of neutrino oscillations. We survey existing experimental bounds on this scale, which arise mostly from ? and B decays. In many cases the new physics scale is constrained to be above a few TeV. We also discuss the operators which are either weakly constrained or, at present, subject to no experimental bounds.

Effect of Protein Supplement Sources on Intake and Digestion of Steers Fed Low-quality Forage  

E-Print Network (OSTI)

Potential protein supplements to grazing cattle were evaluated in two projects. In the first project, Karanja seedcake samples were prepared and ruminally incubated using the in situ method to measure nutrient disappearance in cattle consuming low-quality forage. Organic matter and CP were fractionated by degradability into A, B, and C fractions. Organic matter fraction A degradability ranged from 59.6 to 89% (P < 0.05) for all the karanja seedcake samples. Fraction A of CP ranged from 61.6 to 96.2% degradability for all the samples (P < 0.05). Karanja seedcake samples were observed to contain highly degradable nutrients and our results indicate karanja seedcake may possibly be utilized in grazing cattle protein supplements, consequently increasing economic sustainability of biofuel production. In the second experiment, four non-protein nitrogen supplements were ruminally infused in steers consuming low-quality forage. Supplements included a 40% CP mineral mix (40MM), 60% CP mineral mix (60MM), 25% CP liquid (25L), or 35% CP liquid (35L). Protein provision stimulated forage OM intake and total OM intake for both liquid supplements. Forage OM intake tended to be greater for the liquid supplements; 25L (P = 0.06) and 35L (P = 0.08), then control. Total OM intake significantly increased (P < 0.01) for both liquid supplements, when compared to the control treatment. Total digestible OM intake was greater (P < 0.01) for 25L (3.4 kg/d) and 35L (3.36 kg/d) than control (2.94 kg/d). Forage and total OM intake were not significantly affected by 40MM or 60MM treatments. Total tract digestions (OM and NDF) were not observed to be significantly different (P ? 0.11) between supplements and control. Ruminal ammonia was greater (P < 0.01) for all supplements then control and total ruminal VFA concentrations increased from 84.7 to 98.7 mM for control versus supplemented. Supplementation with liquids had a significant effect on intake. Our results indicate of the four supplements, liquid supplements improved the utilization of low-quality forage by cattle, thus improving nutrient stewardship.

Dynamic hohlraum experiments on SATURN  

SciTech Connect

The authors have imploded a 17.5 mm diameter 120-tungsten-wire array weighing 450 {mu}g/cm onto a 4 mm diameter silicon aerogel foam weighing 650 {mu}g/cm, using the pulsed power driver SATURN. A peak current of 7.0 MA drives a 48 ns implosion to strike time followed by 8 ns of foam compression until stagnation. The tungsten strikes the foam with a 50 cm/{mu}s implosion velocity. Radiation temperatures were measured from the side and along the axis with filtered x-ray diode arrays. There is evidence of radiation trapping by the optically thick tungsten from crystal spectroscopy. The pinch is open to less than a 1 mm diameter as measured by time-resolved x-ray framing cameras. The radiation brightness temperature in the foam reaches 150 eV before the main radiation burst or stagnation.

An engineering-economic analysis of combined heat and power technologies in a (mu)grid application  

SciTech Connect

This report describes an investigation at Ernesto Orlando Lawrence Berkeley National Laboratory (Berkeley Lab) of the potential for coupling combined heat and power (CHP) with on-site electricity generation to provide power and heating, and cooling services to customers. This research into distributed energy resources (DER) builds on the concept of the microgrid (mGrid), a semiautonomous grouping of power-generating sources that are placed and operated by and for the benefit of its members. For this investigation, a hypothetical small shopping mall (''Microgrid Oaks'') was developed and analyzed for the cost effectiveness of installing CHP to provide the mGrid's energy needs. A mGrid consists of groups of customers pooling energy loads and installing a combination of generation resources that meets the particular mGrid's goals. This study assumes the mGrid is seeking to minimize energy costs. mGrids could operate independently of the macrogrid (the wider power network), but they are usually assumed to be connected, through power electronics, to the macrogrid. The mGrid in this study is assumed to be interconnected to the macrogrid, and can purchase some energy and ancillary services from utility providers.

THE EVOLUTION OF SOLAR FLUX FROM 0.1 nm TO 160 {mu}m: QUANTITATIVE ESTIMATES FOR PLANETARY STUDIES  

Science Conference Proceedings (OSTI)

Understanding changes in the solar flux over geologic time is vital for understanding the evolution of planetary atmospheres because it affects atmospheric escape and chemistry, as well as climate. We describe a numerical parameterization for wavelength-dependent changes to the non-attenuated solar flux appropriate for most times and places in the solar system. We combine data from the Sun and solar analogs to estimate enhanced UV and X-ray fluxes for the young Sun and use standard solar models to estimate changing visible and infrared fluxes. The parameterization, a series of multipliers relative to the modern top of the atmosphere flux at Earth, is valid from 0.1 nm through the infrared, and from 0.6 Gyr through 6.7 Gyr, and is extended from the solar zero-age main sequence to 8.0 Gyr subject to additional uncertainties. The parameterization is applied to a representative modern day flux, providing quantitative estimates of the wavelength dependence of solar flux for paleodates relevant to the evolution of atmospheres in the solar system (or around other G-type stars). We validate the code by Monte Carlo analysis of uncertainties in stellar age and flux, and with comparisons to the solar proxies {kappa}{sup 1} Cet and EK Dra. The model is applied to the computation of photolysis rates on the Archean Earth.

An 805 MHz pillbox cavity tested at Fermilab's MTA facility showed significant degradation in gradient when operated in a several Tesla solenoidal magnetic field. We have used the advanced ACE3P simulation codes developed at SLAC to study the cavity dark current and multipacting characteristics to gain more insight into the gradient limitations. We also checked whether there is an optimal cavity length that minimizes the dark current impact energy. Finally, we have improved on the cavity design, significantly lowering the fields outside the beam area. These and other results are presented in this paper.

High fluence 1.05 {mu}m performance tests using 20 ns shaped pulses on the Beamlet prototype laser  

SciTech Connect

Beamlet is a single beamline, nearly full scale physics prototype of the 192 beam Nd:Glass laser driver of the National Ignition Facility. It is used to demonstrate laser performance of the NIF multipass amplifier architecture. Initial system characterization tests have all been performed at pulse durations less than 10 ns. Pinhole closure and modulation at the end of long pulses are a significant concern for the operation of NIF. We recently demonstrated the generation, amplification and propagation of high energy pulses temporally shaped to mimic 20 ns long ignition pulse shapes at fluence levels exceeding the nominal NIF design requirements for Inertial Confinement Fusion by Indirect Drive. We also demonstrated the effectiveness of a new conical pinhole design used in the transport spatial filter to mitigate plasma closure effects and increase closure time to exceed the duration of the 20 ns long pulse.

Charge transport properties in CdZnTe detectors grown by the vertical Bridgman technique  

Science Conference Proceedings (OSTI)

Presently, a great amount of effort is being devoted to the development of CdTe and CdZnTe (CZT) detectors for a large variety of applications such as medical, industrial, and space research. We present the spectroscopic properties of some CZT crystals grown by the standard vertical Bridgman method and by the boron oxide encapsulated vertical Bridgman method, which has been recently implemented at IMEM-CNR (Parma, Italy). In this technique, the crystal is grown in an open quartz crucible fully encapsulated by a thin layer of liquid boron oxide. This method prevents contact between the crystal and the crucible, thereby allowing larger single grains with a lower dislocation density to be obtained. Several mono-electrode detectors were realized, with each having two planar gold contacts. The samples are characterized by an active area of about 7 mm x 7 mm and thicknesses ranging from 1 to 2 mm. The charge transport properties of the detectors have been studied by mobility-lifetime ({mu} x {tau}) product measurements, carried out at the European Synchrotron Radiation Facility (Grenoble, France) in the planar transverse field configuration, where the impinging beam direction is orthogonal to the collecting electric field. We have performed several fine scans between the electrodes with a beam spot of 10 {mu}m x 10 {mu}m at various energies from 60 to 400 keV. In this work, we present the test results in terms of the ({mu} x {tau}) product of both charge carriers.

Observational Study of Higher Dimensional Magnetic Universe in Non-linear Electrodynamics  

E-Print Network (OSTI)

In this work, we have considered the flat FRW model of the universe in $(n+2)$-dimensions filled with the dark matter and the magnetic field. We present the Hubble parameter in terms of the observable parameters $\\Omega_{m0}$ and $H_{0}$ with the redshift $z$ and the other parameters like $B_{0},\\omega, \\mu_{0},\\delta,n,w_{m}$. The natures of magnetic field $B$, deceleration parameter $q$ and $Om$ diagnostic have also been analyzed for accelerating expansion of the universe. From Stern data set (12 points), we have obtained the bounds of the arbitrary parameters by minimizing the $\\chi^{2}$ test. The best-fit values of the parameters are obtained by 66%, 90% and 99% confidence levels. Now to find the bounds of the parameters ($B_{0},\\omega$) and to draw the statistical confidence contour, we fixed four parameters $\\mu_{0},\\delta,n,w_{m}$. Here the parameter $n$ determines the higher dimensions and we perform comparative study between three cases : 4D $(n=2)$, 5D $(n=3)$ and 6D $(n=4)$ respectively. Next due to joint analysis with BAO observation, we have also obtained the bounds of the parameters ($B_{0},\\omega$) by fixing other parameters $\\mu_{0},\\delta,n,w_{m}$ for 4D, 5D and 6D. The best fit of distance modulus for our theoretical model and the Supernova Type Ia Union2 sample are drawn for different dimensions.

Feasibility study for a 10-MM-GPY fuel ethanol plant, Brady Hot Springs, Nevada. Volume 1. Process and plant design  

DOE Green Energy (OSTI)

An investigation was performed to determine the technical and economic viability of constructing and operating a geothermally heated, biomass, motor fuel alcohol plant at Brady's Hot Springs. The results of the study are positive, showing that a plant of innovative, yet proven design can be built to adapt current commerical fermentation-distillation technology to the application of geothermal heat energy. The specific method of heat production from the Brady's Hot Spring wells has been successful for some time at an onion drying plant. Further development of the geothermal resource to add the capacity needed for an ethanol plant is found to be feasible for a plant sized to produce 10 million gallons of motor fuel grade ethanol per year. A very adequate supply of feedgrains is found to be available for use in the plant without impact on the local or regional feedgrain market. The effect of diverting supplies from the animal feedlots in Northern Nevada and California will be mitigated by the by-product output of high-protein feed supplements that the plant will produce. The plant will have a favorable impact on the local farming economies of Fallon, Lovelock, Winnemucca and Elko, Nevada. It will make a positive and significant socioeconomic contribution to Churchill County, providing direct employment for an additional 61 persons. Environmental impact will be negligible, involving mostly a moderate increase in local truck traffic and railroad siding activity. The report is presented in two volumes. Volume 1 deals with the technical design aspects of the plant. The second volume addresses the issue of expanded geothermal heat production at Brady's Hot Springs, goes into the details of feedstock supply economics, and looks at the markets for the plant's primary ethanol product, and the markets for its feed supplement by-products. The report concludes with an analysis of the economic viability of the proposed project.

Artificial neural network modeling of the spontaneous combustion occurring in the industrial-scale coal stockpiles with 10-18 mm coal grain sizes  

SciTech Connect

Companies consuming large amounts of coal should work with coal stocks in order to not face problems due to production delays. The industrial-scale stockpiles formed for the aforementioned reasons cause environmental problems and economic losses for the companies. This study was performed in a coal stock area of a large company in Konya, which uses large amounts of coal in its manufacturing units. The coal stockpile with 5 m width, 10 m length, 3 m height, and having 120 tons of weight was formed in the coal stock area of the company. The inner temperature data of the stockpile was recorded by 17 temperature sensors placed inside the stockpile at certain points. In order to achieve this goal, the electrical signal conversion of temperatures sensed by 17 temperature sensors placed in certain points inside the coal stockpile, the transfer of these electrical signals into computer media by using analog-digital conversion unit after applying necessary filtration and upgrading processes, and the record of these information into a database in particular time intervals are provided. Additionally, the data relating to the air temperature, air humidity, atmospheric pressure, wind velocity, and wind direction that are the parameters affecting the coal stockpile were also recorded. Afterwards, these measurement values were used for training and testing of an artificial neural network model. Comparison of the experimental and artificial neural network results, accuracy rates of training and testing were found to be 99.5% and 99.17%, respectively. It is shown that possible coal stockpile behavior with this artificial neural network model is powerfully estimated.

Binuclear transition-metal complexes as new reagents for selective cross-linking of proteins. Coordination of cytochrome c to dirhodium(II). mu. -tetraacetate  

SciTech Connect

This study introduces binuclear transition-metal complexes as reagents for selective covalent cross-linking of proteins. Incubation of horse cytochrome c (designated cyt) with Rh{sub 2}(OAc){sub 4} under mild conditions yields the diprotein complex, Rh{sub 2}(OAc){sub 4}(cyt){sub 2}, whose composition is established by size-exclusion chromatography, uv-vis spectroscopy, and {sup 1}H NMR spectroscopy. The protein molecules are coordinated to the Rh atoms via the imidazole (Im) rings of their His 33 residues, as shown by uv difference and {sup 1}H NMR spectroscopy, by the pH effect on the complex formation, and by the control experiments with tuna cytochrome c. The diprotein complex is stable under ordinary conditions, and yet it can be cleaved, and the native protein recovered, by treatment with a suitable strong nucleophile. Spectroscopic and electrochemical measurements show that the structural and redox properties of cytochrome c are not perturbed significantly by cross-linking. Comparison between Rh{sub 2}(OAc){sub 4}(Im){sub 2} and Rh{sub 2}(OAc){sub 4}(cyt){sub 2} shows that the complex containing small ligands is not an entirely realistic model of the complex containing proteins. In particular, the enhanced stability of the latter toward hydrolysis may be due to steric bulk of the protein ligands and to hydrogen bonds that amino acid side chains may form with the inorganic link. Some of the findings of this study may pertain to the mechanism of antitumor action of the Rh{sub 2}(RCOO){sub 4} complexes. 86 refs., 2 tabs.

Performance of an adaptive mu-focusing Kirkpatrick-Baez system for high-pressure studies at the Advanced Photon Source  

SciTech Connect

X-ray studies of materials in extreme conditions of pressure call for focusing optics able to deliver very clean micron-size focal spots of high energy X-rays with added stringent requirements of flexibility to accommodate different experimental geometries and fast focal spot size adjustment. These requirements are fully met by multi-electrode modular piezoelectric bimorph mirrors (PBMs) in Kirkpatrick-Baez configurations, and these optical systems have already been successfully used for several years at high brilliance 3rd generation synchrotron radiation facilities such as the ESRF and SPring-8. The optical characterization and in-situ X-ray performance of the first pair of modular PBMs installed at the Advanced Photon Source at Argonne national laboratory is reported here. Metrology tests show that the mirrors are able to approximate an arbitrary surface described by a 9th order polynomial in shape with only 100 {angstrom}; rms shape error over their full optical surface. Full adaptive zonal control allows wave front correction, delivers optimum focal spot profiles (as small as 8.5 (H) x 5.0 (V) {micro}m{sup 2} FWHM at a focal distance of 1 m) and fully achieves the creep-free short and long term stability and repeatability required by the experimental program.

Investigation of changes in the angular divergence of helium--neon laser radiation (lambda = 3. 39. mu. ) as a function of the dispersion characteristic of the active medium  

SciTech Connect

The angular divergence of helium--neon laser radiation was found to depend on varation of the emission frequency within the limits of the gain profile of the active medium. The maximum relative change in the angular divergence was 4 +- 2%. This change appeared because of a nonlinear frequency dependence of the refractive index of the active medium in the region of the Doppler-broadened gain profile. The effect appeared particularly clear in the case of long optical paths.

Fine-grained clay fraction (,0.2 {mu}m): An interesting tool to approach the present thermal and permeability state in active geothermal systems  

DOE Green Energy (OSTI)

We have investigated by X-ray diffraction the very fine grained secondary minerals (< 0.2 {micro}m) developed in geothermal systems, in relation with their present thermal and permeability state. Because the smallest particles are the most reactive part of a rock, they are the youngest mineral phases of the geothermal fields. This study has been performed on two active geothermal fields: Milos field, Greece (130 < T < 320 C) and Chipilapa field, Salvador (90 < T < 215 C). In the Milos field, the mineralogical composition of the < 0.2 {micro}m clay fraction observed in the reservoir strongly differs from the overlying altered metamorphic schists in the presence of abundant quantities of saponite and talc/saponite interstratified minerals at unusually high temperature. These phases are considered to be kinetically control-led ''metastable'' minerals which rapidly evolve towards actinolite and talc for present temperatures higher than 300 C. Their occurrence is a good indicator of discharge in highly permeable zones. In the geothermal field of Chipilapa, the mineralogical composition of the < 0.2 {micro}m clay fractions fairly agrees with the temperatures presently measured in the wells, whereas several discrepancies may be pointed out from the compositions of coarser clay fractions (< 5 {micro}m) which contain minerals inherited from higher temperature stages. Permeable zones may be evidenced from an increase of expandable components in the interstratified minerals and a decrease of the coherent domain of the unexpandable clay particles (chlorite).

Very Long Baseline Neutrino Oscillation Experiment for Precise Determination of Oscillation Parameters and Search for nu_mu -> nu_e Appearance and CP Violation  

E-Print Network (OSTI)

The possibility of making a low cost, very intense (1MW) high energy proton source at the Brookhaven Alternating Gradient Synchrotron (BNL-AGS) along with the forthcoming new large underground detectors (approaching 1 MT in mass) at the National Underground Science and Engineering Laboratory (NUSEL) in Homestake, South Dakota or at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico, allows us to propose a program of experiments that will address fundamental aspects of neutrino oscillations and CP-invariance violation. This program is unique because of the very long baseline of more than 2500 km from BNL to the underground laboratory in the West. We used the running scenario of a low energy, wide band neutrino beam with 1 MW AGS, 500 kT of fiducial mass water Cherenkov detector, and 5x10^7 seconds of running time. In this report we show that with these conditions we precisely measure dm^2_32 and sin^2(2theta_23) and have excellent sensitivity to sin^2(2theta_13) with a distinctive signal spectrum. If sin^2(2theta_13) > 0.01 the experiment is sensitive to the CP-violating phase in the mixing matrix with only neutrino running. By running in the anti-neutrino mode we distinguish between the cases dm^2_31 > 0 versus dm^2_31 nu_e appearance channel.

Sodium arsenite impairs insulin secretion and transcription in pancreatic {beta}-cells  

Science Conference Proceedings (OSTI)

Human studies have shown that chronic inorganic arsenic (iAs) exposure is associated with a high prevalence and incidence of type 2 diabetes. However, the mechanism(s) underlying this effect are not well understood, and practically, there is no information available on the effects of arsenic on pancreatic {beta}-cells functions. Thus, since insulin secreted by the pancreas plays a crucial role in maintaining glucose homeostasis, our aim was to determine if sodium arsenite impairs insulin secretion and mRNA expression in single adult rat pancreatic {beta}-cells. Cells were treated with 0.5, 1, 2, 5 and 10 {mu}M sodium arsenite and incubated for 72 and 144 h. The highest dose tested (10 {mu}M) decreased {beta}-cell viability, by 33% and 83%, respectively. Insulin secretion and mRNA expression were evaluated in the presence of 1 and 5 {mu}M sodium arsenite. Basal insulin secretion, in 5.6 mM glucose, was not significantly affected by 1 or 5 {mu}M treatment for 72 h, but basal secretion was reduced when cells were exposed to 5 {mu}M sodium arsenite for 144 h. On the other hand, insulin secretion in response to 15.6 mM glucose decreased with sodium arsenite in a dose-dependent manner in such a way that cells were no longer able to distinguish between different glucose concentrations. We also showed a significant decrease in insulin mRNA expression of cells exposed to 5 {mu}M sodium arsenite during 72 h. Our data suggest that arsenic may contribute to the development of diabetes mellitus by impairing pancreatic {beta}-cell functions, particularly insulin synthesis and secretion.

Soft holographic interference lithography microlens for enhanced organic light emitting diode light extraction  

SciTech Connect

Very uniform 2 {micro}m-pitch square microlens arrays ({micro}LAs), embossed on the blank glass side of an indium-tin-oxide (ITO)-coated 1.1 mm-thick glass, are used to enhance light extraction from organic light-emitting diodes (OLEDs) by {approx}100%, significantly higher than enhancements reported previously. The array design and size relative to the OLED pixel size appear to be responsible for this enhancement. The arrays are fabricated by very economical soft lithography imprinting of a polydimethylsiloxane (PDMS) mold (itself obtained from a Ni master stamp that is generated from holographic interference lithography of a photoresist) on a UV-curable polyurethane drop placed on the glass. Green and blue OLEDs are then fabricated on the ITO to complete the device. When the {mu}LA is {approx}15 x 15 mm{sup 2}, i.e., much larger than the {approx}3 x 3 mm{sup 2} OLED pixel, the electroluminescence (EL) in the forward direction is enhanced by {approx}100%. Similarly, a 19 x 25 mm{sup 2} {mu}LA enhances the EL extracted from a 3 x 3 array of 2 x 2 mm{sup 2} OLED pixels by 96%. Simulations that include the effects of absorption in the organic and ITO layers are in accordance with the experimental results and indicate that a thinner 0.7 mm thick glass would yield a {approx}140% enhancement.

The GGD27 complex includes the HH 80-81-80N system, which is one of the most powerful molecular outflows associated with a high-mass star-forming region observed to date. This outflow is powered by the star associated with the source IRAS 18162-2048. Here, we report on the detection of continuum emission at subarcsec/arcsec resolution with the Submillimeter Array (SMA) at 1.36 mm and 456 {mu}m, respectively. We detected dust emission arising from two compact cores, MM1 and MM2, separated by about 7'' ({approx}12,000 AU in projected distance). MM1 spatially coincides with the powerful thermal radio continuum jet that powers the very extended molecular outflow, while MM2 is associated with the protostar that drives the compact molecular outflow recently found in this region. High angular resolution observations at 1.36 mm show that MM1 is unresolved and that MM2 splits into two subcomponents separated by {approx}1''. The mass of MM1 is about 4 M{sub sun} and it has a size of {approx}<300 AU. This is consistent with MM1 being associated with a massive and dense (n(H{sub 2}) {approx}> 10{sup 9} cm{sup -3}) circumstellar dusty disk surrounding a high-mass protostar, which has not yet developed a compact H II region. On the other hand, the masses of the two separate components of MM2 are about 2 M{sub sun} each. One of these components is a compact core with an intermediate-mass young protostar inside and the other component is probably a prestellar core. MM1 is the brightest source at 1.36 mm, while MM2 dominates the emission at 456 {mu}m. These are the only (sub)millimeter sources detected in the SMA observations. Hence, it seems that both sources may contribute significantly to the bolometric luminosity of the region. Finally, we argue that the characteristics of these two sources indicate that MM2 is probably in an earlier evolutionary stage than MM1.
