Radioactive Kr Isotopes  

Science Journals Connector (OSTI)

A radioactive isotope of 1.1-hour half-life has been produced in krypton by alpha-particle bombardment of Se74, enriched electromagnetically from 0.9 percent to 14.1 percent. Assignment of the isotope is made to Kr77. Aluminum absorption measurements indicate a positron end point of 1.7 Mev. In addition to annihilation radiation, gamma-rays and K-capture have been observed. The ratio of K-capture to positron emission from the Se74(?,n) reaction is computed as 2.6. The krypton 1.42-day isotope has been produced by an ?,n reaction on electromagnetically enriched Se76. The isotope is located as Kr79 and its half-life confirmed. A positron end point of 1.0 Mev is determined by aluminum absorption measurements. In addition to annihilation radiation, gamma-rays and K-capture have been observed. The ratio of K-capture to positron emission from the Se76(?,n) reaction is computed to be 50. The cross-section ratio for formation of Kr77 compared to Kr79 by alpha-particle bombardment of selenium is computed as 1.4. The 4.6-hour Kr85 isotope has been produced by a Se(?,n) reaction.

Collisional and radiative excitation transfers in Kr-Xe mixtures: Quenching of Kr  

Science Journals Connector (OSTI)

A detailed study of electronic energy transfers in Kr-Xe mixtures has been made using a 250-keV electron accelerator to excite Kr-Xe mixtures over a wide range of Kr-host-gas pressure and Xe-impurity concentrations. Kr pressure ranged from 25 to 900 Torr with Xe concentrations varying from 0.1% to 10% of Kr partial pressure. Emission spectra taken in the vacuum-ultraviolet (vuv) region indicate that energy is transferred efficiently from Kr to Xe, with radiation from the Xe(3P1) state becoming greatly enhanced as the Xe-impurity concentration is increased. Emission spectra from the vuv also show that the Xe(1P1) state is populated by absorption of photons emitted from the Kr2 * first continuum. Two-body quenching rates with Xe ground-state atoms have been found for the Kr(1P1) [kq(1165 Ĺ)=1.2×105 sec-1/Torr] and for the Kr(3P1) [kq(1236 Ĺ)=9.5×105 sec-1/Torr] resonance states. Time-resolved measurements have also been made on the Kr2 * first and second continua. These measurements show the Kr(3P1) state is the atomic precursor of the Kr2 * first continuum. The results obtained in the Kr2 * second continuum are rate limited by the decay of Kr(3P1) at large Xe-impurity concentrations.

Synthetic DNA minor groove-binding drugs  

Science Journals Connector (OSTI)

In this review, both cationic and neutral synthetic ligands that bind in the minor groove of DNA are discussed. Certain bis-distamycins and related lexitropsins show activities against human immunodeficiency virus (HIV)-1 and HIV-2 at low nanomolar concentrations. DAPI binds strongly to AT-containing polymers and is located in the minor groove of DNA. DAPI intercalates in DNA sequences that do not contain at least three consecutive AT bp. Berenil can also exhibit intercalative, as well as minor groove binding, properties depending on sequence. Furan-containing analogues of berenil play an important role in their activities against Pneumocystis carinii and Cryptosporidium parvuam infections in vivo. Pt(II)-berenil conjugates show a good activity profile against HL60 and U-937 human leukemic cells. Pt-pentamidine shows higher antiproliferative activity against small cell lung, non-small cell lung, and melanoma cancer cell lines compared with many other tumor cell lines. trans-Butenamidine shows good anti-P. carinii activity in rats. Pentamidine is used against P. carinii pneumonia in individuals infected with HIV who are at high risk from this infection. A comparison of the cytotoxic potencies of adozelesin, bizelesin, carzelesin, cisplatin, and doxorubicin indicates that adozelesin is a potent analog of CC-1065. Naturally occurring pyrrolo[2,1-c][1,4]benzodiazepines such as anthramycin have a 2- to 3-bp sequence specificity, but a synthetic PBD dimer spans 6 bp, actively recognizing a central 5?-GATC sequence. The crosslinking efficiency of PBD dimers is much greater than that of other major groove crosslinkers, such as cisplatin, melphalan, etc. Neothramycin is used clinically for the treatment of superficial carcinoma of the bladder.

Tube support grid and spacer therefor  

DOE Patents [OSTI]

A tube support grid and spacers therefor provide radially inward preloading of heat exchange tubes to minimize stress upon base welds due to differential thermal expansion. The grid comprises a concentric series of rings and spacers with opposing concave sides for conforming to the tubes and V-shaped ends to provide resilient flexibility. The flexibility aids in assembly and in transmitting seismic vibrations from the tubes to a shroud. The tube support grid may be assembled in place to achieve the desired inwardly radial preloading of the heat exchange tubes. Tab and slot assembly further minimizes stresses in the system. The radii of the grid rings may be preselected to effect the desired radially inward preloading.

Multilayer Kr films adsorbed on BN  

Science Journals Connector (OSTI)

We report on the results of an adsorption isotherm study of multilayer Kr films adsorbed on BN. Measurements were conducted on a computer-controlled adsorption apparatus at 22 temperatures in the vicinity of the bulk-triple point of Kr. The data are compared with those available for Kr on graphite. The phase diagrams for both systems are topologically identical in the region between two and five layers. The layer critical temperatures for the second and third layers are essentially identical for Kr on both substrates; the high-temperature solidification transition of the second layer, on the other hand, is shifted on BN relative to where it occurs on graphite. The implications of our results for the current understanding of re-entrant layering are discussed.

Monolayer Kr films adsorbed on BN  

Science Journals Connector (OSTI)

We have conducted a detailed study of Kr films adsorbed on BN. We have performed adsorption-isotherm measurements and calculations for the potential energy of Kr atoms on the surface of BN. Both the experimental and the theoretical results are extensively compared to data for Kr on graphite, as well as to data for N2 and CO on both BN and graphite. For N2 and CO, the energy calculations found similar corrugations on BN and on graphite (these two molecular adsorbates do not discriminate between the B and N atoms on the BN substrate). This is not the case for Kr. The corrugation for Kr atoms (which do discriminate between B and N) is quite different on BN from what it is on graphite. Our adsorption isotherms indicate that a commensurate solid phase is present for Kr on BN. However, this commensurate solid exists only over a surprisingly narrow temperature interval of less than 5 K. Our experimental results are compared with those from previous studies of this system. We offer possible explanations for the differences observed and attempt to present a coherent picture of the experimental situation for this system. © 1996 The American Physical Society.

Dynamics of Kr in dense clathrate hydrates  

Science Journals Connector (OSTI)

The dynamics of Kr atoms as guests in dense clathrate hydrate structures are investigated using site specific Kr83 nuclear resonant inelastic x-ray scattering (NRIXS) spectroscopy in combination with molecular dynamics simulations. The dense structure H hydrate and filled-ice structures are studied at high pressures in a diamond anvil high-pressure cell. The dynamics of Kr in the structure H clathrate hydrate quench recovered at 77 K is also investigated. The Kr phonon density of states obtained from the experimental NRIXS data are compared with molecular dynamics simulations. The temperature and pressure dependence of the phonon spectra provide details of the Kr dynamics in the clathrate hydrate cages. Comparison with the dynamics of Kr atoms in the low-pressure structure II obtained previously was made. The Lamb-Mossbauer factor obtained from NRIXS experiments and molecular dynamics calculations are in excellent agreement and are shown to yield unique information on the strength and temperature dependence of guest-host interactions.

Fabrication of advanced design (grooved) cermet anodes  

SciTech Connect (OSTI)

Attempts were made to fabricate full-size anodes with advanced, or grooved, design using isostatic pressing, slip casting injection molding. Of the three approaches, isostatic pressing produced an anode with dimensions nearest to the target specifications, without serious macroscopic flaws. This approach is considered the most promising for making advanced anodes for aluminum smelting. However, significant work still remains to optimize the physical properties and microstructure of the anode, both of which were significantly different from that of previous anodes. Injection molding and slip casting yielded anode materials with serious deficiencies, including cracks and holes. Injection molding gave cermet material with the best intrinsic microstructure, i.e., the microstructure of the material between macroscopic flaws was very similar to that of anodes previously made at PNL. Reason for the similarity may have to do with amount of residual binder in the material prior to sintering.

Bubble formation and Kr distribution in Kr-irradiated UO2  

SciTech Connect (OSTI)

In situ and ex situ transmission electron microscopy observation of small Kr bubbles in both single-crystal and polycrystalline UO2 were conducted to understand the inert gas bubble behavior in oxide nuclear fuel. The bubble size and volume swelling are shown as a weak function of ion dose but strongly depend on the temperature. The Kr bubble formation at room temperature was observed for the first time. The depth profiles of implanted Kr determined by atom probe tomography are in good agreement with the calculated profiles by SRIM, but the measured concentration of Kr is about 1/3 of calculated one. This difference is mainly due to low solubility of Kr in UO2 matrix, which has been confirmed by both density-functional theory calculations and chemical equilibrium analysis.

Absolute cross sections for the emission of ultraviolet resonance line radiations from Ar and Kr atoms resulting from Ar + Ar and Kr + Kr collisions are reported. The energy range covered extends from near the reaction thresholds to 150 eV in the center-of-mass system. The emission cross sections are found to have energy dependencies very similar to those exhibited by the total ionization cross sections for the same reactants. The techniques used to make the measurements are described and the results are discussed in terms of a current theoretical model of the interactions.

The continuous electron emission in 150-, 450-, and 750-keV Kr-Kr collisions has been studied at a laboratory scattering angle of 15°. The analysis of the spectra in terms of quasimolecular Auger-electron emission superimposed on a "background" of directly ionized electrons indicates that many quasimolecular states are involved. This washes out structural details which have been expected from simple models.

Diffusion of Kr Isotopes in Solid Ar  

Science Journals Connector (OSTI)

The diffusion coefficient D=D0e-Q0RT and isotope effect for Kr78 and Kr86 in solid Ar have been measured using a tracer technique. The activation energy QKr0 depends on the interchange parameter w, but is estimated to lie in the range 3500-3900 cal mole-1, with the most reliable w giving the lower value. Thus, the two calculated QKr0 (3853 and 4050 cal mole-1) for the vacancy mechanism using a two-body (12, 6) potential appear somewhat high, but in reasonable agreement with experiment. The isotope effect gives f?K?(D78D86-1)[(8678)12-1]=0.48±0.25 which, since QKr0?QAr0, suggests that ?K?0.6 for a single-vacancy mechanism. {Here f is the correlation factor and ?K?(?278?286-1)[(8678)12-1], where ?2 is the tracer jump rate.}

Nuclear reactor spacer grid and ductless core component  

DOE Patents [OSTI]

The invention relates to a nuclear reactor spacer grid member for use in a liquid cooled nuclear reactor and to a ductless core component employing a plurality of these spacer grid members. The spacer grid member is of the egg-shell type and is constructed so that the walls of the cell members of the grid member are formed of a single thickness of metal to avoid tolerance problems. Within each cell member is a hydraulic spring which laterally constrains the nuclear material bearing rod which passes through each cell member against a hardstop in response to coolant flow through the cell member. This hydraulic spring is also suitable for use in a water cooled nuclear reactor. A core component constructed of, among other components, a plurality of these spacer grid members, avoids the use of a full length duct by providing spacer sleeves about the sodium tubes passing through the spacer grid members at locations between the grid members, thereby maintaining a predetermined space between adjacent grid members.

Multiple ionization in single, low-MeV collisions of Kr ions with Kr atoms  

Science Journals Connector (OSTI)

The energy and relative intensities of L-MM Auger lines show that for low-MeV Kr+-Kr collisions most of the ionization takes place during the collision, due to the prompt emission of as many as 12 electrons per atom. The later decay of L-shell vacancies contributes in only a minor way to the final ionization state. These results provide insights into a variety of collision phenomena, including shifts in Auger and x-ray energies, fluorescence yields, and equilibrium charge distributions in high-Z foils.

Formation of solid Kr nanoclusters in MgO  

Science Journals Connector (OSTI)

The phenomenon of positron confinement enables us to investigate the electronic structure of nanoclusters embedded in host matrices. Solid Kr nanoclusters are a very interesting subject of investigation because of the very low predicted value of the positron affinity of bulk Kr. In this work, positron trapping in solid Kr nanoclusters embedded in MgO is investigated. The Kr nanoclusters were created by means of 280 keV Kr ion implantation in single crystals of MgO(100) and subsequent thermal annealing at a temperature of 1100 K. The nanoclusters were observed by cross-sectional transmission electron microscopy in high-resolution mode. The fcc Kr nanoclusters are rectangularly shaped with sizes of 2 to 5 nm and are in a cube-on-cube orientation relationship with the MgO host matrix. From the Moiré fringes in high-resolution recordings, the lattice parameter of the solid Kr was deduced and found to vary from 5.3 to 5.8 Ĺ. The corresponding pressures are 0.6–2.5 GPa as found using the Ronchi equation of state. The relationship between lattice parameter and cluster size was investigated and it was found that the lattice parameter increases linearly with increasing nanocluster size. The defect evolution during annealing was monitored by means optical absorption spectroscopy and positron beam analysis. No evidence of positron trapping was found despite the very low positron affinity of solid Kr. Alternative definitions of the positron affinity are proposed for application to insulator materials.

Collective potential energy surfaces of light mass Kr isotopes  

Science Journals Connector (OSTI)

Collective potential energy surface calculations have been performed for Kr74-80 nuclei in the framework of the Gneuss and Greiner model. The collective Hamiltonian is diagonalized in the basis of the five-dimensional quadrupole oscillator. Our calculations suggest that the Kr78,80 nuclei are ? unstable with a triaxial minimum at ??40°. The Kr74,76 nuclei have two axially symmetric minima with the 01+ ground state being located mainly in the deformed minimum, whereas the first excited 02+ state is located in the spherical minimum. The calculations also indicate that the ground state wave function for Kr74 is spread over both the minima.[NUCLEAR STRUCTURE Kr74,76,78,80: Calculated potential energy surfaces; compared with experimental energy levels and B(E2) values.

The MOF material has 20% or more, preferably 40% or more, of the total pore volume in a pore size range of 0.45-0.75 nm which can selectively adsorb Xe over Kr in a multi-component Xe--Kr mixture over a pressure range of 0.01 to 1.0 MPa.

Charge Spectrometry for Kr79-Br79  

Science Journals Connector (OSTI)

The distribution in charge of the Br79 atoms formed in the complex electron capture and ?+ decay of radioactive Kr79 has been found to consist of two components; one to be mostly associated with the ?+ transitions, and the other with the electron capture transitions. Because of a difference in instrumental efficiency, the relative intensity of the two components is undetermined in the present work, but if the value of 9.3 is assumed for the total electron-capture/?+ ratio, then the spectrum for the successive charges -1, 0, +1...+13 is as follows (figures in percent): 7.7, 3.7 (estimated), 4.0, 4.7, 12.7, 16.0, 14.3, 13.6, 11.3, 7.7, 3.3, 0.68, 0.13, 0.054, and 0.014, respectively.

Evidence for Deformed Ground States in Light Kr Isotopes  

Science Journals Connector (OSTI)

The levels in Kr74,76 were studied with in-beam ?-spectroscopy techniques and the ?+ decay of Rb76. The energies of the 21+ states in Kr74,76 deviate from smooth behavior compared with the higher spin levels. The yrast cascade B(E2)'s are highly collective. The Kr74,76 ground states have unusually large deformation. The origin of this deformation and of shape coexistence in this region is described in terms of the protons driving the deformation.

Hybrid plasmonic waveguide in a metal V-groove  

SciTech Connect (OSTI)

We propose and investigate a type of hybrid plasmonic waveguide in a metal V-groove. A high-permittivity nanowire was placed in the metal channel covered with a dielectric film of lower permittivity. Deeper sub-wavelength confinement and much longer propagation distance were achieved in comparison with conventional channel plasmonic waveguides. The overall performance was improved as compared with the conventional hybrid plasmonic structure based on a flat metal surface. Finite element analysis showed that both the mode propagation and field profile can be adjusted by changing the nanowire radius and film thickness. Some benefits, such as a reduced scattering loss caused by the surface roughness, are also expected owing to the unique mode profile. The proposed approach has potential for application in high-level photonic integration.

Nuclear matter radii of neutron-deficient Kr isotopes  

Science Journals Connector (OSTI)

Interaction cross sections (?I) of Kr72,76,80 on a C target were measured at the projectile fragment separator FRS at GSI. Effective matter radii of the nuclei were deduced by a Glauber model analysis so as to reproduce the experimental ?I. An increase of matter radii toward the proton drip-line is observed. We compare the extracted radii to theoretical predictions, which are based on Skyrme-Hartree-Fock-Bogoliubov (SHFB) and on relativistic mean field (RMF) approaches. The enhancement of the matter radius observed in Kr72 is discussed.

The thermally activated inversion of Kr-Xe bilayers on Pd is studied with the use of photoemission and photon-excited Auger spectroscopy. Bilayers formed by the deposit of a monolayer or less of Xe on top of a monolayer of Kr on Pd at 49 K are shown to invert when the temperature is raised, with Xe coming in direct contact with the substrate. For a Pd(111) substrate the activation energy of this inversion process is determined: Ea=0.12±0.03 eV.

High power KrF laser development at Los Alamos  

SciTech Connect (OSTI)

The objective of the high power laser development program at Los Alamos is to appraise the potential of the KrF laser as a driver for inertial confinement fusion (ICF), ultimately at energy levels that will produce high target gain (gain of order 100). A KrF laser system prototype, the 10-kJ Aurora laser, which is nearing initial system operation, will serve as a feasibility demonstration of KrF technology and system design concepts appropriate to large scale ICF driver systems. The issues of affordable cost, which is a major concern for all ICF drivers now under development, and technology scaling are also being examined. It is found that, through technology advances and component cost reductions, the potential exists for a KrF driver to achieve a cost goal in the neighborhood of $100 per joule. The authors suggest that the next step toward a multimegajoule laboratory microfusion facility (LMF) is an ''Intermediate Driver'' facility in the few hundred kilojoule to one megajoule range, which will help verify the scaling of driver technology and cost to an LMF size. An Intermediate Driver facility would also increase the confidence in the estimates of energy needed for an LMF and would reduce the risk in target performance. 5 refs., 4 figs., 1 tab.

High-accuracy mass measurements of neutron-rich Kr isotopes  

Science Journals Connector (OSTI)

The atomic masses of the neutron-rich krypton isotopes Kr84,86-95 have been determined with the tandem Penning trap mass spectrometer ISOLTRAP with uncertainties ranging from 20 to 220 ppb. The masses of the short-lived isotopes Kr94 and Kr95 were measured for the first time. The masses of the radioactive nuclides Kr89 and Kr91 disagree by 4 and 6 standard deviations, respectively, from the present Atomic-Mass Evaluation database. The resulting modification of the mass surface with respect to the two-neutron separation energies as well as implications for mass models and stellar nucleosynthesis are discussed.

Sublimation Pressures of Solid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

Results of an experiment to measure the sublimation pressures of Ar, Kr, and Xe over wide temperature and pressure ranges are presented. Data are reported from near the respective triple points to about (2.3 × 10-6 Torr, 25.506 K) for Ar; (2.1 × 10-4 Torr, 45.130 K) for Kr; (3.8 × 10-4 Torr, 70.075 K) for Xe. Pressures were measured with a Hg manometer, a McLeod gauge, and a calibrated Bourdon gauge. The data have been corrected for thermomolecular flow and streaming. Temperatures were measured with a N.B.S.-calibrated Pt resistance thermometer. The application of the law of corresponding states is investigated. Values for static lattice energy, geometric mean of the lattice vibrational spectrum, heat of sublimation, and lattice vibrational energy are calculated using theoretical sublimation pressure curves.

Photoemission from Ar, Kr, and Xe on Pb(111)  

Science Journals Connector (OSTI)

Angle-resolved photoelectron spectra were measured for the valence p states of Ar, Kr, and Xe on Pb(111). The thickness of the rare-gas layers was varied between 0.05 and about 5 monolayers. For each layer the work function was deduced from the width of the photoelectron energy-distribution curve. On Pb(111) tightly packed monolayers were prepared, exhibiting energy dispersion of the valence p states, which is discussed in the framework of the known two-dimensional band structure. The spectral features are very sharp, as can be seen from the full width at half maximum value of 175 meV for the Xe 5p1/2 peak. For Xe the submonolayer regime was also studied, where single atoms are adsorbed together with small three-dimensional clusters. The single atoms exhibit no dispersion and no split of the p3/2 level into two sublevels. This demonstrates that these features are derived from lateral interaction in the rare-gas monolayer. On top of the monolayer a second completely filled layer can be prepared for Ar, Kr, and Xe. The second-layer shift in binding energy is 720 meV for Ar and Kr and 525 meV for Xe. It is about 6 times as large as the work-function changes induced by the monolayer. This observation can only be explained in the known final-state interpretation of the layer-dependent shifts in binding energy.

Positronium scattering from Kr and Xe at low energies  

Science Journals Connector (OSTI)

The scattering of orthopositronium from Kr and Xe is investigated with the fixed core stochastic variational method. The scattering lengths for Ps-Kr and Ps-Xe scattering in the fixed core approximation are 3.18a0 and 3.82a0, respectively. Inclusion of core-polarization potentials leads to a significant reduction in the scattering lengths. The Ps-Kr and Ps-Xe scattering lengths were 1.98a0 and 2.29a0 for polarization potentials that were tuned to an average of the model electron-atom and positron-atom scattering lengths for the respective atoms. Other choices of the polarization potential resulted in scattering lengths that could be larger by 0.3a0 or smaller by 0.8a0. The pick-off annihilation parameter 1Zeff has also been computed as part of the analysis. The present values of 1Zeff are about 3 to 10 times smaller than the accepted experimental values since short-range electron-positron correlations were ignored when the annihilation matrix element was evaluated.

Differential measurements of ionization and inelastic energy losses in 0.25—3.0-MeV collisions of Kr ions with Kr and Xe targets  

Science Journals Connector (OSTI)

The final charge states of the scattered ions and the inelastic energy losses have been measured for single collisions of 0.25—3.0-MeV Kr ions with Kr and Xe targets. The charge states of the scattered ions were measured as functions of scattering angle (from 0.8° to 45°) ion energies from 0.25 to 3.0 MeV. The total inelastic energy losses were measured using the scattered- and recoil-particle coincidence technique for 0.4-, 0.6-, and 1.0-MeV Kr+-Kr collision energies and from 0.4 to 1.4 MeV for the Kr+-Xe combination. The results show the impact-parameter dependence of several inner-shell excitations and confirm the quasimolecular nature of heavy-ion—atom collisions within the framework of the Fano-Lichten model. For the Kr-Kr case, excitations are observed for values of the distance of closest approach, R0, of 0.40, 0.30, and 0.20 Ĺ; and for the Kr-Xe case, excitations are observed at R0 values of 0.28, 0.18, and 0.09 Ĺ. The data show agreement with the molecular-potential calculations of Eichler and co-workers.

Increase of the electron mobility in HEMT heterostructures with composite spacers containing AlAs nanolayers  

SciTech Connect (OSTI)

The effect of the hybridization of quantum states on electron transport in a two-barrier quantum well ?-doped through a spacer layer at the limit of heavy doping is shown theoretically and experimentally. A method for increasing the electron mobility in the quantum well by suppressing the tunnel coupling with the donor region through the introduction of an AlAs nanobarrier into the spacer layer is proposed. It is experimentally shown that, in the samples with a shallow quantum well, the AlAs nanobarrier introduced into the spacer layer provides a larger than threefold increase in the electron mobility at low temperatures.

Method of forming a spacer for field emission flat panel displays  

DOE Patents [OSTI]

Spacers are disclosed for applications such as field emission flat panel displays and vacuum microelectronics, and which involves the application of aerogel/xerogel technology to the formation of the spacer. In a preferred approach the method uses a mold and mold release agent wherein the gel precursor is a liquid which can be applied to the mold filling holes which expose the substrate (either the baseplate or the faceplate). A release agent is applied to the mold prior to precursor application to ease removal of the mold after formation of the dielectric spacer. The shrinkage of the gel during solvent extraction also improves mold removal. The final spacer material is a good dielectric, such as silica, secured to the substrate. 3 figs.

System design and performance of a spiral groove gas seal for hydrogen service  

SciTech Connect (OSTI)

In the past, typical seal designs for low molecular weight gases, such as hydrogen, incorporated high pressure oil seal systems. Technology of the seventies and eighties produced a new concept - the spiral groove gas seal. This paper discusses the problems related to oil seal systems, as well as the design, application and performance of a dry gas seal. It also discusses the limitations encountered with the start-up and operation of a dry gas seal in a high pressure, oil-soluble mixture of light hydrocarbons. Results show how the spiral groove gas seal can handle adverse demands without seal failure.

Metastable-atom desorption and luminescence stimulated by low-energy electron impact on condensed Kr, Xe, and Xe/Kr films  

Science Journals Connector (OSTI)

Metastable-atom desorption and uv luminescence from thin films of Kr and Xe on Pt(111) stimulated by impact of monochromatic low-energy electrons (E=5–25 eV, ?E=60 meV) have been studied. For either pure rare-gas film, the excitation function of the total luminescence signal shows two broad peaks that are presumably related to the interplay between creation of excitons and free-electron–hole pairs. Metastable-particle desorption is very weak for pure Kr and not detectable for pure Xe over the entire range of electron energies. However, for 35-ML Kr films covered with 1-ML Xe (ML denotes monolayer), a considerable signal due to metastable-particle desorption is observed. The energy dependence of the signal in the 8–12.6-eV region leads to an interpretation of the desorption in the form of two different mechanisms with different thresholds. The first one is based on the creation of a Xe exciton in a Kr environment, while in the second scheme the excitation energy is transferred from a Kr bulk exciton to a Xe atom at the Kr-Xe interface. In both cases, repulsive Kr-Xe* interaction near the film surface is postulated to eject a metastable Xe* atom.

Charge Transport in Solid and Liquid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

This paper reports an investigation of the drift velocity of excess electrons in solid and liquid Ar, Kr, and Xe. After purification of the commercially available gas, thin crystal specimens (100-600 ?m) were grown from the liquid between parallel electrodes in a chamber attached to a miniature cryostat. Pulses of 40-keV electrons were used to generate the charge carriers in both liquids and solids. This technique overcomes the limitations inherent in previously applied methods and has made it possible to investigate the drift velocity over a range of applied fields from 10 V cm-1 to 100 kV cm-1. Near the triple point, the low-field mobility ?0 in solid Ar, Kr, and Xe was found to be 1000, 3700, and about 4500 cm2sec-1V-1, respectively. In the liquids the corresponding mobilities were 475, 1800, and 2200 cm2sec-1V-1. The temerature dependence of ?0 has been measured on Ar crystals, and the results indicate that ?0 is determined by acoustic scattering. The electron lifetime appears to be controlled predominantly by oxygen impurities. Pronounced hot-electron effects are observed in drift-velocity—versus—field curves for both liquids and solids, and their fit to the Shockley hot-electron theory has been investigated. In the high-field region all the curves show an almost complete saturation with field. The theory of Cohen and Lekner applied to liquid Ar fits the results over most of the field range, suggesting that the deviations from the Shockley theory at higher electron temperatures are associated with an increase in the value of the structure factor. In solid Ar or Kr, positive holes do not appear to be mobile, but in Xe crystals a hole mobility of about 2×10-2 cm2sec-1V-1 was found. The implications of these results are briefly discussed.

Structural Determination of the Hydrophobic Hydration Shell of Kr  

Science Journals Connector (OSTI)

We report the first direct measurement by extended x-ray absorption fine structure spectroscopy of the hydrophobic hydration shell of the noble gas krypton. Measurements were made in aqueous solution at gas pressures in the range 20 to 100 bars and at a temperature of 320 K. Data of excellent quality were collected taking advantage of the high brilliance of a third generation synchrotron radiation source. An advanced data analysis procedure has been applied to determine the Kr-O partial radial distribution function in the short range.

Decay of the resonantly excited states of atomic Kr  

Science Journals Connector (OSTI)

The 3p-1?5s1 resonant excitation energy and decay width of Kr atoms are calculated by an ab initio Green’s-function method. The dipolar relaxation energy shift of the 3p-1?5s1 resonantly excited state of Kr atoms is predominantly due to the 3p-15s1?3d-25s1?f super-Coster-Kronig (sCK) spectator decay process. The calculated excitation energies are overestimated by about 1.0 eV. The decay widths for 3p1/2-1?5s1 and 3p3/2-1?5s1 resonantly excited states are 2.08 and 1.88 eV, respectively. They are larger than the decay widths of the 3p1/2-1 and 3p3/2-1 core-level ionized states. The increase of the decay width is a result of the decrease of 3p-15s1?3d-25s1?f sCK spectator decay and the increase of 3p-15s1?3d-14s(p)-15s1?p(d) CK spectator decay. The changes of the (s)CK decay rates are due to the screening of the final two-hole-state potential by the resonantly excited 5s electron.

Boson effective charges for light Se, Kr, and Sr isotopes  

Science Journals Connector (OSTI)

A consistent analysis of E2 transition probabilities for nine neutron-deficient even-even Se, Kr, and Sr isotopes has been performed, based on previous parametrizations for these nuclei within the proton-neutron interacting-boson model, from which boson effective charges e? and e? are deduced. Two sets of effective charges are obtained, one set having e??e? for most of the nuclei studied, and the other set having e? substantially larger than e? for most of the nuclei. For both sets, e? tends to decrease with increasing neutron number, while e? is roughly constant. More information on mixed-symmetry states is needed to determine which set is valid.

Multipacting in a grooved choke joint at SRF gun for BNL ERL prototype  

SciTech Connect (OSTI)

The 703 MHz superconducting gun for BNL ERL prototype was tested at JLab with and without choke-joint and cathode stalk. Without choke-joint and cathode stalk, the gradient reached was 25 MV/m with Q{sup 0} {approx} 6E9. The gun cathode insertion port is equipped with a grooved choke joint for multipacting suppression. We carried out tests with choke-joint and cathode stalk. The test results show that there are at least two barriers at about 3.5 MV/m and 5 MV/m. We considered several possibilities and finally found that fine details of the grooved shape are important for multipacting suppression. A triangular groove with round crest may cause strong multipacting in the choke-joint at 3.5 MV/m, 5 MV/m and 10 MV/m. This paper presents the primary test results of the gun and discusses the multipacting analysis in the choke-joint. It also suggests possible solutions for the gun and multipacting suppressing for a similar structure.

Ionization, charge exchange, and excitation in F + Ar and F + Kr collisions  

Science Journals Connector (OSTI)

We have measured projectile and target x-ray cross sections for F + Ar and F + Kr collisions using fluorine beams of charge states 7 +, 8 +, and 9+ with energies from 20 to 76 MeV. Pronounced enhancements for the Ar K and Kr L vacancy cross sections using F9+ ions compared to those for the 7+ projectile can be explained by charge exchange as described by an empirically scaled Brinkman-Kramers theory. The Ar L, Kr K and Kr M cross sections are found to exhibit features expected for Coulomb ionization. The projectile K x-ray production for the 9+ ion is accounted for by charge exchange processes. Predictions of the first Born approximation for direct single-step excitation to bound states by the target nucleus overestimate the observed cross sections for F7+ and F8+.

Numerical atomic basis orbitals from H to Kr  

Science Journals Connector (OSTI)

We present a systematic study for numerical atomic basis orbitals ranging from H to Kr, which could be used in large scale O(N) electronic structure calculations based on density-functional theories (DFT). The comprehensive investigation of convergence properties with respect to our primitive basis orbitals provides a practical guideline in an optimum choice of basis sets for each element, which well balances the computational efficiency and accuracy. Moreover, starting from the primitive basis orbitals, a simple and practical method for variationally optimizing basis orbitals is presented based on the force theorem, which enables us to maximize both the computational efficiency and accuracy. The optimized orbitals well reproduce convergent results calculated by a larger number of primitive orbitals. As illustrations of the orbital optimization, we demonstrate two examples: the geometry optimization coupled with the orbital optimization of a C60 molecule and the preorbital optimization for a specific group such as proteins. They clearly show that the optimized orbitals significantly reduce the computational efforts, while keeping a high degree of accuracy, thus indicating that the optimized orbitals are quite suitable for large scale DFT calculations.

Novel electromagnetic technique for repositioning of coolant tube spacers in CANDU nuclear reactors  

Science Journals Connector (OSTI)

A novel electromagnetic technique to reposition the coolant tube spacers in the fuel channels of CANDU nuclear reactors was successfully developed in the fall of 1983 at Ontario Hydro Research Division. The need to reposition dislocated spacers in noncommissioned reactors was discovered subsequent to the rupture of a pressure tube in one reactor at the Pickering Nuclear Generator Station in Ontario. A contributing factor to the failure of the tube was the fact that the annular spacers (garter springs) used to maintain the coaxial configuration between the pressure tube and its surrounding calandria tube had been displaced longitudinally for a number of years. Subsequent to this finding it was discovered that a number of garter springs in noncommissioned nuclear reactors were displaced due to vibration induced by various sources during the construction stage. Since the garter springs are not directly accessible by mechanical means extensive dismantling of the fuel channels would have been necessary to reposition the springs in their designated locations. This paper describes a novel method to reposition the garter springs without dismantling the fuel channels. The method consists of exerting a force on the springs in the direction of the required displacement by applying a large electromagnetic impulse (generated by a 200?kJ capacitor bank) to a drive coil inserted into the pressure tube opposite the spacer. The repositioning of displaced garter springs in five new reactors in Ontario has been carried out successfully in 1984. The saving in reactor repair cost interest charges and replacement energy cost was on the order of hundreds of millions of dollars. Equally large benefits and savings will be realized if the need to use this technique in commissioned reactors arises. Also the related development of strong compact coils and low?resistance pulse power cable have significant implications and advantages in various other applications related to the pulse power industry in general and to electromagnetic metal forming and fusion technologies specifically.

Multiple ionization of Ar, Kr, and Xe in a superstrong laser field  

Science Journals Connector (OSTI)

We report the numerical calculation of Ar9+? Ar13+, Kr13+? Kr17+, and Xe19+? Xe23+ ion yield in the laser field with intensity exceeding 1019 W/cm2. The results of the calculations agree with the experimental data [K. Yamakava et al., Phys. Rev. A 68, 065403 (2003)] quantitatively (for the Ar ions) or qualitatively (for the Kr ions). The theoretical results disagree with the experimental data for the Xe ions. We discuss the possible influence of the relativistic effects on this disagreement between theory and experiment. We obtained the approximation formula for the position of the maximum ionic population with the given ionization multiplicity Z depending on the radiation intensity. This position is described by the power function of Z; the exponent is determined by the dependence of sequential ionization potentials on Z value. We discuss the dependence of the approximation formula parameters on the value of the FWHM of the laser pulse.

A saturated-absorption experiment is used to measure the effects of velocity-changing collisions between Kr* metastable atoms (4p55s[32]2) and He and Ar perturbers. Comparison between experimental profiles and profiles calculated assuming hard-sphere collisions between Kr* and perturber atoms confirms the calculations of Borenstein and Lamb concerning the change of velocity associated with a collision. Furthermore it is found that the rate of velocity-changing collisions is consistent with the predictions of kinetic theory.

Ultracold ionizing collisions of laser-cooled Kr isotopes in the 1s5[4p55s:3P2] metastable state are investigated. When the collision energy is reduced below the p-wave centrifugal barrier of 80 ?K, the ratio of the ionizing collision rate between polarized and unpolarized Kr83 atoms is found to decrease. This is a direct evidence of the quantum interference of two identical Fermi particles. The experimental results are compared with the calculation based on the simplified inelastic collision theory.

Operation characteristics of cylindrical miniature grooved heat pipe using aqueous CuO nanofluids  

SciTech Connect (OSTI)

An experimental study was performed to investigate the operation characteristics of a cylindrical miniature grooved heat pipe using aqueous CuO nanofluid as the working fluid at some steady cooling conditions. The experiments were carried out under both the steady operation process and the unsteady startup process. The experiment results show that substituting the nanofluid for water as the working fluid can apparently improve the thermal performance of the heat pipe for steady operation. The total heat resistance and the maximum heat removal capacity of the heat pipe using nanofluids can maximally reduce by 50% and increase by 40% compared with that of the heat pipe using water, respectively. For unsteady startup process, substituting the nanofluid for water as the working fluid, cannot only improve the thermal performance, but also reduce significantly the startup time. (author)

Elastic scattering of intermediate-energy electrons by Ar and Kr  

Science Journals Connector (OSTI)

Using the relative-flow technique elastic differential cross sections ?? (Ar or Kr ) for Ar and Kr relative to ?? (He) have been measured at impact energies of 3, 5, 7.5, 10, 15, 20, 30, 50, 75, and 100 eV. The angular range covered is from 20° to 135°. These ratios have been multiplied by the recently measured values of ??(He) to obtain ??(Ar or Kr ). The differential cross section curves for both Ar and Kr show deep minima. The positions of these minima have been obtained with an accuracy of ±2°. The cross sections in the angular regions lying between 0° and 20° and 135° and 180° could not be measured owing to instrumental limitations. In these regions estimates of the shapes of differential cross section (DCS) curves have been made by fitting the data obtained from 20° to 135° with a phase-shift analysis, while the normalization to the absolute scale was obtained by normalizing these fits to the relative flow measurements. From these estimates and the measured values of the differential cross section, integral and momentum-transfer cross sections have been obtained. The error limits for the differential, integral, and momentum-transfer cross sections have been estimated as 20, 30, and 30%, respectively.

Commensurate-incommensurate transition of Kr-Xe mixtures on graphite  

Science Journals Connector (OSTI)

We report high-resolution x-ray scattering measurements of the commensurate-incommensurate transition of Kr on graphite which has been preplated with 0.1 monolayer of Xe. The Xe raises transition pressure, and produces a 31% range of pressures over which composite lineshapes are observed. These results are discussed in terms of a solubility gap between commensurate and incommensurate phases.

Adsorption of Kr, Xe, and Ar on highly uniform MgO smoke  

Science Journals Connector (OSTI)

The first atomic layer of Kr, Xe, and Ar adsorbed on MgO smoke is explored by using adsorption isotherms. A procedure has been developed by which we produce MgO smoke powders of higher homogeneity than previously reported. On these powders, apparent two-dimensional (2D) solid-vapor, fluid-vapor, and solid-fluid coexistence regions are observed for Kr and Xe. Triple-point temperatures are estimated to be 66.6±0.5 K and 100.8±1.0 K, and the critical temperatures are estimated to be 86.8±1.0 K and 119±2.0 K, respectively, for these two elements. A comparison between Kr and Xe 2D-solid densities at the fluid-solid transition suggests that the 2D-solid phases are incommensurate with the substrate. The Ar isotherms are qualitatively different from those of Kr and Xe, showing no features corresponding to 2D phase transitions in the P-T range studied. A qualitative estimate places the Ar 2D critical temperature at about 65 K.

SPACE-R nuclear power system SC-320 thermionic fuel element performance tests  

SciTech Connect (OSTI)

In 1993 and 1994, the Russian Scientific Research Institute NII NPO ``LUCH`` and Space Power, Inc., (SPI), of San Jose, California, developed a prototype of the single-cell thermionic fuel element (TFE) for the SPACE-R space nuclear power system (NPS). The SPACE-R system was designed as a part of the US Department of Energy`s (DOE) Space Reactor Development Program to develop a long life, space reactor system capable of supplying up to 40 kW(e) output power. The jointly developed SC-320 TFE is a prototype of the next generation thermionic converter for nuclear applications in space. This paper presents the results of the initial demonstration tests and subsequent parametric evaluations conducted on the SC-320 TFE as compared to the calculated performance characteristics. The demonstration tests were conducted jointly by Russian and American specialists at the Thermionic Evaluation Facility (TEF) at the New Mexico Engineering Research Institute (NMERI) of the University of New Mexico in Albuquerque.

The effect of anterior proton beams in the setting of a prostate-rectum spacer  

SciTech Connect (OSTI)

Studies suggest that anterior beams with in vivo range verification would improve rectal dosimetry in proton therapy for prostate cancer. We investigated whether prostate-rectum spacers would enhance or diminish the benefits of anterior proton beams in these treatments. Twenty milliliters of hydrogel was injected between the prostate and rectum of a cadaver using a transperineal approach. Computed tomography (CT) and magnetic resonance (MR) images were used to generate 7 uniform scanning (US) and 7 single-field uniform dose pencil-beam scanning (PBS) plans with different beam arrangements. Pearson correlations were calculated between rectal, bladder, and femoral head dosimetric outcomes and beam arrangement anterior scores, which characterize the degree to which dose is delivered anteriorly. The overall quality of each plan was compared using a virtual dose-escalation study. For US plans, rectal mean dose was inversely correlated with anterior score, but for PBS plans there was no association between rectal mean dose and anterior score. For both US and PBS plans, full bladder and empty bladder mean doses were correlated with anterior scores. For both US and PBS plans, femoral head mean doses were inversely correlated with anterior score. For US plans and a full bladder, 4 beam arrangements that included an anterior beam tied for the highest maximum prescription dose (MPD). For US plans and an empty bladder, the arrangement with 1 anterior and 2 anterior oblique beams achieved the highest MPD in the virtual dose-escalation study. The dose-escalation study did not differentiate beam arrangements for PBS. All arrangements in the dose-escalation study were limited by bladder constraints except for the arrangement with 2 posterior oblique beams. The benefits of anterior proton beams in the setting of prostate-rectum spacers appear to be proton modality dependent and may not extend to PBS.

Initial proof-of-principle for near room temperature Xe and Kr separation from air with MOFs  

SciTech Connect (OSTI)

Materials were developed and tested in support of the U.S. Department of Energy, Office of Nuclear Energy, Fuel Cycle Technology Separations and Waste Forms Campaign. Specifically, materials are being developed for the removal of Xenon and krypton from gaseous products of nuclear fuel reprocessing unit operations. During FY 2012, Three Metal organic framework (MOF) structures were investigated in greater detail for the removal and storage of Xe and Kr from air at room temperature. Our breakthrough measurements on Nickel based MOF could capture and separate parts per million levels of Xe from Air (40 ppm Kr, 78% N2, 21% O2, 0.9% Ar, 0.03% CO2). Similarly, the selectivity can be changed from Xe > Kr to Xe < Kr simply by changing the temperature in another MOF. Also for the first time we estimated the cost of the metal organic frameworks in bulk.

Photoattenuation in the extreme red wings of Xe and Kr resonant lines  

Science Journals Connector (OSTI)

Photoattenuation coefficients are reported for high-pressure xenon and krypton at wavelengths in the red wings of the first resonant lines [Xe(P13), ?0=1470 Ĺ and Kr(P13), ?0=1236 Ĺ]. The measurements cover the range 2000-20 000 cm-1 from the resonant lines. The photoattenuation spectra are interpreted in terms of Rayleigh scattering and photoabsorption by atoms, Van der Waals molecules, and unbound diatomic molecules—different portions of the spectra are dominated by different species and phenomena. Absorption by unbound diatomic molecules is interpreted via a quasistatic model of the molecule. Analysis of the data in this manner yields information concerning the structure and radiative lifetime of the lowest-bound diatomic states of Xe2* and Kr2*. The significance of the results reported here in regards to dissociative noble-gas lasers (transition from a bound diatomic level to the repulsive ground level) is discussed.

Multielectron inner-shell photoexcitation in absorption spectra of Kr: Theory and experiment  

Science Journals Connector (OSTI)

The probability of Kr 1s photoionization alone and accompanied by 4p, 3d, 3p, 2s, and 2s4p excitations has been calculated as a function of photon energy in the vicinity of the respective thresholds; pertinent energies have been computed including relativistic, quantum-electrodynamic, and relaxation effects. Sharp features from two-electron excitations are expected in absorption spectra only if at least one of the electrons undergoes a transition to a bound state; this becomes less probable in inner shells. An absorption-spectrometry experiment on Kr has been performed with synchrotron radiation; results generally confirm the predictions but also point toward refinements that are required in the theory and the need for improvements in techniques and synchrotron-radiation sources.

Velocity-dependent total scattering cross sections for metastable helium on Kr and Xe  

Science Journals Connector (OSTI)

Single-beam attenuation measurements of velocity-dependent total scattering cross sections for the interactions of metastable helium (He*) on Kr and Xe targets have been measured in the 1-5-km/s relative-velocity range. The results are compared with cross sections obtained by full quantum calculations for a Lennard-Jones (12-6) potential with the parameters ? and ? adjusted for a best fit. The results (in atomic units) are ?=3.38×10-4 a.u., ?=7.80 a.u., for the He*+Kr system and ?=5.34×10-4 a.u. and ?=7.79 a.u. for the He*+Xe system.

Resolution of hyperfine transitions in metastable 83Kr using Electromagnetically Induced Transparency  

E-Print Network [OSTI]

Narrow linewidth signals of Electromagnetically Induced Transparency (EIT) in the metastable 83Kr have been observed for the first time. Various hyperfine transitions in 4p55s[3/2]2 to 4p55p[5/2]3 manifolds of 83Kr have been identified through the experimentally observed EIT signals. Some unresolved or poorly resolved hyperfine transitions in saturated absorption spectroscopy (SAS) are clearly resolved in the present work. Using the spectral separation of these EIT identified hyperfine transitions, the magnetic hyperfine constant (A) and the electric quadrupole hyperfine constant (B) are determined with improved accuracy for 4p55s[3/2]2 and 4p55p[5/2]3 manifolds.

Gamma-gamma directional correlation measurements in 84Kr following thermal neutron capture by natural krypton  

Science Journals Connector (OSTI)

Directional correlations of gamma-ray cascades in 84Kr have been measured following thermal neutron capture by a pressurised natural krypton gas target. Gamma-ray singles spectra were measured up to 5.5 MeV and the correlation data were obtained for the energy range 0.2-2.5 MeV. A decay scheme was developed on the basis of coincidence measurements. The data allow spin-parity assignments to be made to most levels lying below 3.5 MeV and multipole mixing ratios to be evaluated for the more intense transitions. The results are fitted to the SU(5) limit of the IBM-1 and to the IBM-2 and are also compared with the predictions of the dynamic deformation model which indicates that 84Kr is the only krypton isotope with a prolate equilibrium shape. A possible mixed symmetry 2+ state at 2.623 MeV is identified.

Soft-x-ray-emission spectra of solid Kr and Xe  

Science Journals Connector (OSTI)

We present the first soft x-ray-emission spectra for solid Kr (4p-3d) and Xe (5p-4d) that are free of complicating satellite spectra. Monochromatic synchrotron-radiation excitation is used to suppress the satellites. The data are analyzed to determine the P3/2 bandwidth for both elements; these results are compared with both photoemission data and available theoretical calculations. Bandwidths are found to be larger than those predicted by most electronic structure calculations.

Using conventional time to pulse-height techniques, the lifetimes of the low-lying levels in La137 and Kr83 have been measured, despite the low ?-ray energies (10 and 9.3 keV) and the large internal conversion coefficients (130 and 11). The results of 89±4 and 147±4 nsec, respectively, correspond to retardation factors of 370 and 45 over the single-particle model predictions for those M1 transitions.

Elastic Constants of Solid Ar, Kr, and Xe: A Monte Carlo Study  

Science Journals Connector (OSTI)

The elastic constants of classical systems of 108 particles arranged (with periodic boundary conditions) on an fcc lattice and interacting with pairwise-additive forces have been evaluated to an accuracy of about 2% by a Monte Carlo procedure closely related to that used by Hoover and his co-workers. For Ar(80 °K) and Kr(85 and 115 °K) we have used the Bobetic-Barker pair potentials and also included the corrections for the truncated tail of the pair potential, quantum effects, and three-body forces. For Ar(80 °K) and Xe(156 °K) we have carried out a similar calculation for the familiar Lennard-Jones 6:12 potential. Our 6:12 Ar(80 °K) elastic constants agree well with the previous work of Hoover et al. but unfortunately differ only little from the more realistic Bobetic-Barker Ar(80 °K) values. Bulk moduli for both potentials are compatible with the currently available experimental data. Comparison of our Kr results with experimental data indicates a need for refinement of the Bobetic-Barker Kr potential. The Xe(156 °K) results agree very well with the recent Brillouin-scattering work of Gornall and Stoicheff which is to some extent disappointing because the same 6:12 potential is in poor agreement with the low-temperature heat capacity.

Differential excitation cross sections have been measured for Kr 4p6(1S0)?4p5(2P1/2,3/2)5s transitions at 300- and 500-eV impact energies and for 1.5°–10° scattering angles by electron-energy-loss spectroscopy. The integrated cross sections for these impact energies are reported here. The generalized oscillator strengths have also been obtained to determine the optical oscillator strengths. The errors are estimated to be less than 15%.

Polycrystalline iron foils implanted to high krypton doses, in order to produce rare-gas inclusions, were doped with In111 and the magnetic hyperfine field as well as the electric-field gradient was measured. Time-differential perturbed angular correlation experiments were performed in the as-implanted and the annealed sample condition. We observed a substantial fraction of probe atoms in a ‘‘defect site,’’ characterized by the hyperfine interaction parameters ??Bhf?=-6.89(4)% and Vzz?2.6×1017 V/cm2, in close similarity with those expected for the Kr/Fe interface. The impact of the present approach for metal surface studies is stressed.

Evidence for a Smooth Onset of Deformation in the Neutron-Rich Kr Isotopes  

Science Journals Connector (OSTI)

The neutron-rich nuclei Kr94,96 were studied via projectile Coulomb excitation at the REX-ISOLDE facility at CERN. Level energies of the first excited 2+ states and their absolute E2 transition strengths to the ground state are determined and discussed in the context of the E(21+) and B(E2;21+?01+) systematics of the krypton chain. Contrary to previously published results no sudden onset of deformation is observed. This experimental result is supported by a new proton-neutron interacting boson model calculation based on the constrained Hartree-Fock-Bogoliubov approach using the microscopic Gogny-D1M energy density functional.

Disappearance of rotational flow and reaction plane dispersions in Kr+Au collisions

Two-particle azimuthal correlations have been used to extract reaction plane dispersion free triple-differential cross sections for d, t, and ? particles for the midcentral collisions of 84Kr+197Au at E/A=35, 55, and 70 MeV. Both experimental measurements and extrapolations from lower incident energies suggest that rotational flow disappears at E/A?100 MeV for light charged particles and that reaction plane dispersions introduce large uncertainties in extracting the disappearance of rotational flow.

Unusual degree of angular anisotropy in the resonant Auger spectrum of Kr  

Science Journals Connector (OSTI)

The angular distribution parameter, ?, has been measured for the resonant Auger spectra in Kr following 3d?5p excitation. Unusually low values, close to -1, were seen for two bands. From optical spectroscopy data these bands are assigned to the final states 4p4(3P)5p(4P5/2, 4P3/2, and 4D5/2). According to angular momentum transfer theory, some of the transitions could be parity unfavored, yielding ? values of -1, but additional theory is required for a complete understanding. Implications for angular studies of highly resolved Auger spectra are discussed.

The recently proposed symmetry-conserving energy density functional approach [G. Hupin, D. Lacroix, and M. Bender, Phys. Rev. C 84, 014309 (2011)] is applied to perform variation after projection onto the good particle number using the Skyrme interaction, including density-dependent terms. We propose a simplification to reduce the numerical effort to perform the variation. We present a systematic study of the Kr and Sn isotopic chains. This approach leads to nonzero pairing in magic nuclei and a global enhancement of the pairing gap compared to the original theory, which breaks particle number symmetry.

Balmer-line emission from low-energy H impact on Kr and Xe  

Science Journals Connector (OSTI)

Absolute cross sections for the emission of Balmer-? and Balmer-? radiation have been measured for H+Kr and H+Xe collisions. Measurements were made for H-atom energies from 2.5 to 0.04 keV. The polarizations of the emitted radiations were also determined and, for H-atom energies above 0.2 keV, the contributions to these emissions from decay of the long-lived 3s and 4s excited states of hydrogen were resolved. The results are discussed in comparison with similar data for H-atom impact on the other rare-gas atoms.

Atomic-force-microscopy observations of tracks induced by swift Kr ions in mica  

Science Journals Connector (OSTI)

For the first time, latent tracks induced by swift Kr ions have been directly observed in mica. These tracks are imaged by atomic-force microscopy as hollows which are associated with softer areas in the mica surface. The track core is formed by disordered mica. The mean diameter of the observed hollows increases with the electronic stopping power of the ions. The track shape along the ion path is deduced from the analysis of both the number of the tracks per unit area and their diameter distribution. These observations are the first images of nanometric changes of elastic properties.

Evidence for a highly deformed oblate 0{sup +} state in {sub 36}{sup 74}Kr  

SciTech Connect (OSTI)

We present the observation of an isomeric decay in the very neutron deficient nucleus {sub 36}{sup 74}Kr. The isomer is interpreted as an excited 0{sup +} state, consistent with the long standing prediction of high deformation prolate/oblate shape coexistence in this nucleus. The magnitude of the E0 matrix element deduced for the 0{sub 2}{sup +}{r_arrow}0{sub 1}{sup +} transition gives strong support to the prediction of a highly deformed oblate rotor. {copyright} {ital 1997} {ital The American Physical Society}

Definitive evidence of interlayer coupling between Ga{sub 1-x}Mn{sub x}As layers separated by a nonmagnetic spacer  

SciTech Connect (OSTI)

We have used polarized neutron reflectometry to study the structural and magnetic properties of the individual layers in a series of AlGaAs:Be/Ga{sub 1-x}Mn{sub x}As/GaAs/Ga{sub 1-x}Mn{sub x}As multilayer samples. Structurally, we observe that the samples are virtually identical except for the GaAs spacer thickness (which varies from 3 to 12 nm), and confirm that the spacers contain little or no Mn. Magnetically, we observe that for the sample with the thickest spacer layer, the Ga{sub 1-x}Mn{sub x}As layer adjacent to the Be-doped AlGaAs cap has a temperature dependent magnetization very different from that of the other Ga{sub 1-x}Mn{sub x}As layer. However, as the spacer layer thickness is reduced, the temperature dependent magnetizations of the two Ga{sub 1-x}Mn{sub x}As layers become progressively more similar--a trend we find to be independent of the crystallographic direction along which spins are magnetized. These results definitively show that Ga{sub 1-x}Mn{sub x}As layers can couple across a nonmagnetic spacer and that such coupling depends on spacer thickness.

Measurement of the Atomic Scattering Factor of Ne, Ar, Kr, and Xe  

Science Journals Connector (OSTI)

To test the accuracy of the Hartree-Fock (HF) method and the reliability of x-ray measurements of the atomic scattering factor f, we have determined the scattering of Mo K? radiation by Ne, Ar, Kr, and Xe gases. Values of f were obtained on an absolute basis with an accuracy of about Ľ%. Results at small angle yield the mean-square radius of the electron cloud ?r2?av and the dispersion correction. For Ne, Ar, and Kr, the values of ?r2?av are in good agreement with HF calculations. For Xe, the experimental value is significantly lower. Susceptibility results yield about 6% lower values in each case. Our derived values of the dispersion correction are each more negative than those obtained from published absorption coefficients. At higher angles, our f values differ by less than 0.2 electron unit from the HF values for all the gases; even for Xe the approximate HF values presently available are more nearly accurate than the Thomas-Fermi-Dirac (TFD) values. We conclude that a 4% discrepancy between theory and experiment found by Batterman, Chipman, and DeMarco for metal powders arose from solid-state effects or from difficulties in sample preparation.

Mutual diffusion in binary Ar-Kr mixtures and empirical diffusion models  

Science Journals Connector (OSTI)

Molecular dynamics simulations of four binary Ar-Kr mixtures are used to compute self- and mutual-diffusion coefficients. Results using mean squared displacements and using velocity correlation functions are presented. The diffusivity coefficients are also presented in the time and frequency domains where a comparatively low frequency structure is evident in some simulations. The computed diffusivities are dependent on the maximum time over which the velocity correlation functions are integrated and the time at which the Einstein relationships are evaluated. This dependence explains in part the small systematic differences between our results (20–80 ps) and earlier molecular dynamics results (<4 ps) in the system Ar-Kr. We compare the computed mutual diffusion coefficients to two empirical models, Darken’s model and the common force model. Darken’s model is consistent with our results over the entire frequency range we resolve. At frequencies lower than about 5 ps-1 Darken’s model and the common force model converge and we cannot discriminate between them. At higher frequencies the common force model prediction is significantly different from the computed mutual diffusion coefficient. Assumptions regarding the contribution of cross correlations that are implicit in the empirical models are discussed and tested against our simulation results. The net contribution of velocity cross correlations is found to be negligible, as is often assumed in deriving Darken’s model, but the individual cross-correlation terms are substantial and negative—a finding contrary to common assumptions. © 1996 The American Physical Society.

XANES of high-pressure Kr clusters in Be and Si  

Science Journals Connector (OSTI)

We report on the experimental investigation of high-pressure Kr clusters in Be and Si single crystals by x-ray absorption near-edge spectroscopy. The samples, obtained by ion implantation, were investigated for several temperatures in the range 83–670 K. We show that the near-edge structure of the absorption spectra is sufficient to obtain valuable quantitative information concerning the contracted lattice parameter of the solid rare gas agglomerates, depending on the overpressure exerted on the clusters by the host matrix. Our data compare to the extended x-ray absorption fine structure (EXAFS) experimental spectra on solid Kr at 4.2 K, and at 300 K under high pressure. Furthermore, in order to check the consistency of our experimental data with EXAFS results taken from the literature, we performed theoretical simulations using the FEFF6 code. These calculations showed good agreement with both sets of data and confirmed our experimental conclusions, permitting the evaluation of the lattice contraction, average coordination, and size of the cluster ensemble.

85Kr management trade-offs: a perspective to total radiation dose commitment  

SciTech Connect (OSTI)

Radiological consequences arising from the trade-offs for /sup 85/Kr waste management from possible nuclear fuel resource recovery activities have been investigated. The reference management technique is to release all the waste gas to the atmosphere where it is diluted and dispersed. A potential alternative is to collect, concentrate, package and submit the gas to long-term storage. This study compares the radiation dose commitment to the public and to the occupationally exposed work force from these alternatives. The results indicate that it makes little difference to the magnitude of the world population dose whether /sup 85/Kr is captured and stored or chronically released to the environment. Further, comparisons of radiation exposures (for the purpose of estimating health effects) at very low dose rates to very large populations with exposures to a small number of occupationally exposed workers who each receive much higher dose rates may be misleading. Finally, cost studies (EPA 1976 and DOE 1979a) show that inordinate amounts of money will be required to lower this already extremely small 80-year cumulative world population dose of 0.05 mrem/person (<0.001% of natural background radiation for the same time period).

KrF laser path to high gain ICF (inertial confinement fusion) laboratory microfusion facility  

SciTech Connect (OSTI)

The krypton-fluoride laser has many desirable features for inertial confinement fusion. Because it is a gas laser capable of operation with high efficiency, it is the only known laser candidate capable of meeting the driver requirements for inertial fusion energy (IFE) production. Los Alamos National Laboratory has defined a program plan to develop KrF lasers for IFE production. This plan develops the KrF laser and demonstrates the target performance in single-pulse facilities. A 100-kJ Laser Target Test Facility (LTTF) is proposed as the next step, to be followed by a 3 to 10-MJ Laboratory Microfusion Facility (LMF). The LTTF will resolve many target physics issues and accurately define the driver energy required for the LMF. It is also proposed that the technology development for IFE, such as the high-efficiency, high-reliability, repetitively pulsed driver, the reactor, mass production of targets, and the mechanism of injecting targets be developed in parallel with the single-pulse facilities. 11 refs., 4 figs.

Ionization of the He, Ne, Ar, Kr, and Xe isoelectronic series by proton impact  

Science Journals Connector (OSTI)

In this paper we report ionization cross sections of positive Li+, Na+, K+, Rb+, neutral He, Ne, Ar, Kr, Xe, and negative F?, Cl?, Br?, I? ions by impact of protons with energies ranging from 25to1000keV. Cross sections of singly charged ions are relevant to the calculation of electron yields in collisions with insulator surfaces. Calculations were performed within the continuum distorted wave–eikonal initial state method using an angular expansion in spherical harmonics and a numerical evaluation of the radial functions corresponding to both the initial (bound) and the final (continuum) states. The first Born approximation was used on an equal footing. We find that this first-order theory holds for proton energies larger than 300keV. For comparison, we also calculate the shellwise local plasma approximation. Our results show that it gives a good account of the cross sections for neutral targets.

Laser-induced quadrupole-quadrupole collisional energy transfer in Xe-Kr systems  

Science Journals Connector (OSTI)

Experimental investigation of laser-induced quadrupole-quadrupole collisional energy transfer between Xe and Kr is reported in this paper. The excitation spectrum of laser-induced collisional energy transfer (LICET) is characterized by a slowly decreasing tail on the blue side of the peak and a width of ?30 cm?1. The experimental evidence shows that in the quasistatic wing the quadrupole-quadrupole LICET spectrum follows a power law that is different from the dipole-dipole LICET line shape and the profile of the quadrupole-quadrupole LICET decreases more slowly than the dipole-dipole LICET profile. The results indicate that the laser-induced quadrupole-quadrupole collision can be considered as a practical process to transfer energy selectively from a storage state making a parity-nonallowed transition to a target state making a parity-allowed transition.

Difference between zero- and first-sound propagation in solid Kr  

Science Journals Connector (OSTI)

We point out that the zero-sound-first-sound difference in solid rare gases is a very sensitive probe of the phonon self-energy. Recent advances in our knowledge of the interatomic potentials of these solids have enabled us to remove much of the ambiguity from this source and hence focus directly on the influence of different model self-energies. We have investigated the approximations of Koehler and Goldman, Horton, and Klein using a self-consistent harmonic basis with no explicit inclusion of hard-core effects. We find that the previously unexplained experimental result for solid Kr near melting, that C44 as measured by neutron scattering is 12% greater than obtained from Brillouim scattering, lies between the predictions of these two approximations.

Observation of depinning phenomena in the sliding friction of Kr films on gold  

Science Journals Connector (OSTI)

We have used quartz crystal microbalance to study the sliding friction of atomically thin Kr films adsorbed on gold. We have observed sharp pinning transitions separating a low-coverage region, characterized by slippage at the solid-fluid boundary, from a high-coverage region where the film is locked to the oscillating electrodes. Furthermore, we have induced sliding of a film by slowly increasing the amplitude of the substrate oscillations. Such a depinning transition is characterized by hysteresis as the amplitude is decreased back to zero. These observations have been obtained with two different quartz plates and are similar to those recently reported in the literature. A more quantitative comparison among the different experimental runs indicate that the location of these dynamical transitions is strongly dependent on the state of the substrate surface.

Prototype grooved and spherically bent Si backscattering crystal analyzer for meV resolution inelastic x-ray scattering  

SciTech Connect (OSTI)

The high-order backscattering reflections from single crystals of silicon have mrad rocking curve widths that can be exploited to produce meV energy-resolution focusing analyzer crystals for use in inelastic x-ray scattering experiments at third-generation synchrotron sources. The first generation of these analyzers has been limited in efficiency principally by slope and/or figure errors. We calculate the effect of slope errors on the theoretical energy resolution and focus spot size of a typical analyzer design using a ray-tracing code to ensure that there are no unforeseen contributions to the energy resolution and efficiency. We also present measurements of the slope errors of the atomic planes for a prototype, spherically bent, strain-relief grooved analyzer as proof that it is in principle possible to obtain the slope and figure error limits required for a high efficiency meV resolution backscattering crystal.

Angular distribution of ejected electrons in resonant Auger processes of Ar, Kr, and Xe  

Science Journals Connector (OSTI)

Angle-resolved electron spectroscopy with the help of synchrotron radiation has been used to study resonant Auger processes near the core shells of Ar 2p, Kr 3d, and Xe 4d. Results for the lowest-energy resonances have received special attention: argon (Ar 2p3/2?4s) at a photon energy of 244.4 eV, krypton (Kr 3d5/2?5p) at 91.2 eV, and xenon (Xe 4d5/2?6p) at 65.1 eV. The angular distribution parameters ? are evaluated for each of the resolved Auger peaks. Most striking is the occurrence of large negative ? values for some of the higher kinetic energy peaks. The results are most apparent under high electron resolution. The theoretical basis for having ? values near -1 is discussed. In particular, the experimental results for argon are found to be in general agreement with the prediction of -1 ? values by using either angular momentum transfer theory or normal Auger theory. However, a better understanding of the range of ? values will have to await explicit calculations. Experimental results on the Auger spectra are also given at lower kinetic energies, for shakeup states, and for higher-energy resonances, especially those involving vacancies in the core shells of the lower spin states. It is shown that, although transitions having the same final state of the singly charged ion frequently have similar relative intensities and ? values, occasionally they differ quite markedly. The theoretical consequences of variant behavior for processes having the same final states are also discussed.

Nanoscale topographic pattern formation on Kr{sup +}-bombarded germanium surfaces  

SciTech Connect (OSTI)

The nanoscale pattern formation of Ge surfaces uniformly irradiated by Kr{sup +} ions was studied in a low-contamination environment at ion energies of 250 and 500 eV and at angles of 0 Degree-Sign through 80 Degree-Sign . The authors present a phase diagram of domains of pattern formation occurring as these two control parameters are varied. The results are insensitive to ion energy over the range covered by the experiments. Flat surfaces are stable from normal incidence up to an incidence angle of {theta} = 55 Degree-Sign from normal. At higher angles, the surface is linearly unstable to the formation of parallel-mode ripples, in which the wave vector is parallel to the projection of the ion beam on the surface. For {theta} {>=} 75 Degree-Sign the authors observe perpendicular-mode ripples, in which the wave vector is perpendicular to the ion beam. This behavior is qualitatively similar to those of Madi et al. for Ar{sup +}-irradiated Si but is inconsistent with those of Ziberi et al. for Kr{sup +}-irradiated Ge. The existence of a window of stability is qualitatively inconsistent with a theory based on sputter erosion [R. M. Bradley and J. M. Harper, J. Vac. Sci. Technol. A 6, 2390 (1988)] and qualitatively consistent with a model of ion impact-induced mass redistribution [G. Carter and V. Vishnyakov, Phys. Rev. B 54, 17647 (1996)] as well as a crater function theory incorporating both effects [S. A. Norris et al., Nat. Commun. 2, 276 (2011)]. The critical transition angle between stable and rippled surfaces occurs 10 Degree-Sign -15 Degree-Sign above the value of 45 Degree-Sign predicted by the mass redistribution model.

Cosmiclike domain walls in superfluid B3: Instantons and diabolical points in (k,r) space  

Science Journals Connector (OSTI)

The possible planar superfluid B-B boundaries between inequivalent B-phase vacua are considered; such B-B interfaces provide an analogy with the cosmic domain walls that are believed to have precipitated in the phase transitions of the early Universe. Several of them display nontrivial structure in (k,r) space (i.e., the union of the momentum and real spaces). Such a wall represents an instanton connecting two B-phase vacua with different k-space topology. The transition between the vacua occurs through the formation of a pointlike defect either in the (k,r) space, or in the (k,t) space. These defects are so-called diabolical points of codimension 4, at which the fermionic energy tends to zero, thus providing the fermionic zero modes. Such points are new examples (within condensed-matter physics) of the peculiar diabolical points, which are characterized by the occurrence of a contact between the different branches of the quasiparticle spectra; in the present case, the branches of particles and holes, respectively. These points are here discussed for the case of the superfluid phases of liquid He3 in close analogy with the quantum field theory of fermions interacting with classical bosonic fields. The cosmiclike domain walls in superfluid B3 are observable in principle; in particular, the motion of the superfluid A-B interface is governed at low temperatures by the periodical emission of these topological excitation planes. The edges of B-B interfaces serve to generate fractionally quantized pure and mixed mass and spin supercurrent vortices in B3, while holes in these surfaces may give rise to the corresponding vortex rings and combined vortex and/or spin-disclination rings.

Development of a new feed channel spacer for reverse osmosis elements. Phase 2 final report, October 1, 1994--December 31, 1997  

SciTech Connect (OSTI)

During Phase 1, computer modeling techniques were used as the prime instrument of evaluation of designs for a new feed channel spacer to replace the 30 mil thick standard mesh (Vexar) spacer currently used in ROWPU [Reverse Osmosis Water Processing Unit] spiral-wound elements. A hemispherical peg model, based on a Bed of Nails concept developed in Phase 1, was selected for prototype production of spiral-wound elements for field testing. Evaluation in the See-Thru test cell to observe pressure drops through the spacer, feed mixing patterns and ease of cleaning fouled membrane samples showed considerable benefit over Vexar. This design would be suitable for production by roll embossing (or rotary punching) methods instead of expensive injection molding techniques. A 10{1/2} inch die set was fabricated to prove this concept using a 12 ton press brake. Due to a number of factors, however, the equipment did not work as anticipated and numerous modifications are currently in progress. This work will continue at no cost to the government until completed. A seawater test system has been constructed for field testing of various commercially available feed channel spacers for comparison with the Vexar spacer.

Superconductivity in LiFeO2Fe2Se2 with anti-PbO-type spacer layers  

Science Journals Connector (OSTI)

We report on a superconductor LiFeO2Fe2Se2 with Tc?43 K, synthesized via the hydrothermal method. The anti-PbO-type spacer layer of LiFeO2 has been successfully intercalated between the anti-PbO-type FeSe layer, which results in a high-Tc superconductivity in this iron selenide material. In this material, the LiFeO2 layer is electrically neutral and does not act as an electron donor, which is remarkably different from other heavily electron-doped intercalated FeSe-derived superconductors. Based on our results and previous reports on FeSe-based superconductors, we figure out a V-shaped anion height from the Fe layer dependence of Tc in the FeSe-derived superconductors, which is in contrast to the inverse V-shaped one for the FeAs-based superconductors. Our studies expand the categories of the iron-based superconductors and open a door in the quest for potential superconductors with various spacer layers, which is helpful for the study of the underlying physics in iron-based high-Tc superconductors.

Studies conducted at the Pacific Northwest National Laboratory (PNNL) in Richland, Washington focused on assessing the effectiveness of nondestructive examination (NDE) techniques for inspecting control rod drive mechanism (CRDM) nozzles and J-groove weldments. The primary objective of this work is to provide information to the United States Nuclear Regulatory Commission (US NRC) on the effectiveness of NDE methods as related to the in-service inspection of CRDM nozzles and J-groove weldments, and to enhance the knowledge base of primary water stress corrosion cracking (PWSCC) through destructive characterization of the CRDM assemblies. Two CRDM assemblies were removed from service, decontaminated, and then used in a series of laboratory NDE and DE measurements; this report addresses the following questions: 1) What did each NDE technique detect?, 2) What did each NDE technique miss?, 3) How accurately did each NDE technique characterize the detected flaws?, and finally 4) What were the basis for the NDE techniques performance? Two CRDM assemblies including the CRDM nozzle, the J-groove weld, buttering, and a portion of the ferritic head material were selected for this study. This paper focuses on a CRDM assembly that contained suspected PWSCC, based on in-service inspection data and through-wall leakage. The laboratory NDE measurements used to examine the CRDM assembly followed standard industry techniques for conducting in-service inspections of CRDM nozzles and the crown of the J-groove welds and buttering. These techniques included eddy current testing, time of flight diffraction ultrasound, and penetrant testing. In addition, other laboratory-based NDE methods were employed to conduct inspections of the CRDM assembly with particular emphasis on inspecting the J-groove weld and buttering. These techniques included volumetric ultrasonic inspection of the J-groove weld metal, visual testing via replicant material of the J-groove weld and high resolution photography of the J-groove weld crown and buttering. The results from these NDE studies were used to guide the development of the destructive characterization plan. The NDE studies found several crack-like indications. The NDE and DE studies determined that one of these was a through-weld radially-oriented PWSCC crack in the wetted surface of the J-groove weld, located at the transition point between the weld and the buttering. The crack was 6 mm long on the surface and quickly grew to 25 mm long at a depth of 8 mm, covering the length of the weld between the penetration tube and the carbon steel. The NDE studies found that only ET was able to detect the through-weld crack. The crack was oriented poorly for the ultrasonic testing, and was too tight for accurate PT or VT. The ET voltage response of the flaw was 30% that of a deep EDM notch. The DE performed on the crack consisted of slicing the crack into thin sections, polishing the sections, and then using optical and scanning electron microscopy (SEM) to characterize the crack. DE shows the crack was PWSCC and that it initiated on the wetted surface, grew and expanded through the weld metal, and exited into the annulus. The SEM examinations showed the crack followed the weld grain boundaries as it progressed through the weld. The crack was branched and discontinuous along its length.

Relativistic study of vuv radiation properties from Kr-Xe gas mixtures  

Science Journals Connector (OSTI)

In an effort to obtain a microscopic understanding of the origin of vuv emission from inert heavy-atom gas mixtures we present results from relativistic calculations of the krypton-xenon spectrum in the 68 000 cm-1 region. Calculations carried out on the interatomic interaction in the ground and in the low-lying spin-orbit excited states [0-(3P2), 0+(3P1), 1(3P1), 1(3P2), 2(3P1)] of the krypton-xenon dimer are presented. The calculations were executed in a two-step procedure in which the CCSD(T) model for the ground state and the CCSD response theory model for the excited states were used to obtain spin-free potential curves in the first step. A perturbational treatment of the spin-orbit interaction within the atomic mean-field approximation was applied in the next step. Large-core quasirelativistic effective core potentials with richly augmented valence basis sets and midbond functions were used. All calculations were corrected for basis set superposition errors by applying the counterpoise method. For all involved states, spin-orbit perturbed potential energy curves were computed and equilibrium geometries, potential well depths, and local extrema were determined. Vibrational analysis and Franck-Condon factors for the ground and 0+(3P1),1(3P1) states were also calculated. The geometry dependence of the electronic dipole transition matrix elements between all involved excited states and the ground state was investigated. Excitation energies and potentials were obtained that are in excellent agreement with results based on fitting to experimental data. Out of some earlier disparate experimental assignments of the character of the excited states of the KrXe complex, the present results adhere most closely to the ones presented by Pibel et al. [J. Chem. Phys. 101, 10 242 (1994)]. Analyzed together with the experimental data, the theoretical results provide a clear picture of the organization of exciplex states and of the origin of strong vuv emission from these states that follows from binary collisions of the heavy inert Kr and Xe atoms.

Operational air pollution prediction and doses calculation in case of nuclear emergency at Krško Nuclear Power Plant  

Science Journals Connector (OSTI)

The paper presents fully operational air pollution prediction and doses calculation system working in 2/24/7/365 mode for more than a decade in Krško Nuclear Power Plant (NPP). Krško NPP lies in complex terrain in Slovenia very close to Croatia border. A dedicated software is available for detailed estimation of possible radioactive emission (source term). This part of the procedure is used by trained NPP operators and then automatically coupled with dilution coefficients to obtain radionuclide air pollution concentrations. As radioactive material causes dose also with distant cloud shine not only by direct touch or inhalation, special procedure is implemented for dose estimation. We present in detail our algorithm for distant cloud shine estimation based on dilution coefficients calculation. The paper concludes by stressing the importance of correct air pollution prediction with best possible modelling techniques where achieving time and space accurate modelling is required for proper population protection.

Influence of Kr doping on neon soft X-rays emission in fast miniature plasma focus device  

Science Journals Connector (OSTI)

Abstract An investigation on the possibility of enhancement of soft X-ray (SXR) (900–1600 eV) emission from a fast miniature plasma focus (FMPF) device of 235 J (at 14 kV) storage energy through doping of operating gas was performed. Neon (Ne), the operating gaseous medium, was doped with krypton (Kr) in different volumetric ratios at various operating pressures ranging from 2 to 14 mbar. The 1% Kr doping increased the average optimum SXR emission efficiency from 0.47% to 0.6% without enhancing the hard X-ray (HXR) (>1600 eV) emission. The Kr doping influenced the major pinching characteristics such as focusing efficiency and time to pinch with consequential effect on X-ray emissions. Synchronous operation of the 4 pseudo-spark gap (PSG) switches was mandatory for efficient discharge current delivery to the electrodes. A drastic improvement in the pinching efficiency was obtained with replacement of old and worn out PSG switches with the new ones. Optical imaging of current sheath dynamics was performed using gated ICCD camera to verify the normal operation of the device after the \\{PSGs\\} replacement. A numerical simulation analysis on the 2 cm long stainless steel tapered anode, used in this study, was done to predict the maximum SXR emission efficiency and the peak operating gas pressure. An analysis on the amount of SXR fluence generated at the source position and the proportion of it reaching the target position is also reported.

Hole transport in the rare-gas solids Ne, Ar, Kr, and Xe  

Science Journals Connector (OSTI)

This paper reports an investigation of the drift mobility of excess holes in solid Ne, Ar, Kr, and Xe. Thin-crystal specimens (50-500 ?m thick) were grown from the liquid between parallel-plate electrodes in a chamber attached to a miniature cryostat after purification of the starting gas. As in previous work on the electron transport in rare-gas solids and liquids, an electron-beam technique was used to generate excess carriers near one of the electrodes. Holes were extracted by the applied field and their transit time was measured directly, leading to the drift mobility ?h. Close to the triple points, ?h values in the above crystals lie between 1 × 10-2 and 4 × 10-2 cm2 V-1 sec-1, several orders of magnitude lower than the corresponding electron mobilities. The form of the temperature dependence of ?h changes progressively from Xe (?h?T-1.6) to an essentially activated mobility in Ar and Ne. The experimental results have been analyzed in terms of small-polaron theory, using both the adiabatic and nonadiabatic approximations. The theory can account for the different forms of the temperature dependence and possible ranges of values for the predominant phonon energy, the polaron binding energy and the transfer energy for holes have been deduced in each case. These quantities, characterizing the hole hopping transport, vary systematically from Xe to Ne and their correlation is discussed in some detail.

One-Electron Theory of the Bulk Properties of Crystalline Ar, Kr, and Xe  

Science Journals Connector (OSTI)

The cohesive energy as a function of lattice constant and the P-V relation for Ar, Kr, and Xe have been calculated at T=0 K in the static-lattice limit. The calculation employed the self-consistent augmented-plane-wave statistical-exchange (APW-X?) method, which, except for our own preliminary work, has not heretofore been applied to the study of the bulk properties of a van der Waals crystal. The agreement with experiment is at least semiquantitative with respect to the cohesive energies. The comparison with extant P V data is acceptable. By use of a static-lattice sum of a pair-potential function with undetermined parameters, an effective pair potential is determined, with fairly realistic parameter values as a result. Comparison with other energy-band calculations shows that the occupied one-electron energies found in this calculation are in good agreement with those found by other workers. The conduction-band energies are not a result that is usual in X? calculations. The over-all trends found in this calculation are related to those found by Averill in a recent APW-X? calculation on the alkali metals.

Structural and elastic properties of Ge after Kr-ion irradiation at room temperature  

Science Journals Connector (OSTI)

Changes in the elastic properties of Ge induced by room-temperature irradiation with 3.5-MeV Kr ions have been determined and correlated with changes in the microstructure determined by transmission electron microscopy. Elastic-shear-moduli changes were measured by Brillouin scattering, and changes in local atomic arrangement were determined by Raman scattering. Amorphization decreased the elastic shear modulus of Ge by 17%. The fractional decrease was correlated with the amorphous volume fraction with a cross section of 4.5±0.5 nm2/ion. No change was observed in the shear modulus during void formation and growth. The elastic properties of the voided material are described by the Voigt averaging. However, as the voids evolved into a fibrous spongelike microstructure, a second dramatic elastic softening occurs which we attribute to the inability of the fibrous structure to support shear stresses. Raman scattering showed that, once formed, there was no change in the structure of the amorphous material at the atomic scale during void formation and subsequent void coalescence.

Ionization-induced blue shift of KrF laser pulses in an underdense plasma  

Science Journals Connector (OSTI)

The ionization-induced blue-shifted spectra for helium, neon, and nitrogen have been measured at various gas densities up to 5×1020 cm-3 at a vacuum intensity of 8×1016 W/cm2 for picosecond KrF laser pulses at 248 nm. A 1-mm diameter gas jet target was used in the experiment to minimize the refraction of the laser beam and thus higher laser intensities were obtained in the gas than in previously reported experiments. For helium, a distinct shifted peak was observed at intermediate densities which was not seen before. For helium and nitrogen, spectra were also measured of the light scattered outside of the original focal cone angle. In this region there was little signal for electron densities below 2×1020 cm-3 consistent with limited refraction at lower densities and at higher densities the spectra were predominantly blue shifted. These results indicate the importance of refraction in the correct interpretation of ionization blue-shifted spectra. © 1996 The American Physical Society.

Surface instability on a metal target from multi-pulse KrF laser ablation  

SciTech Connect (OSTI)

Aluminum targets were ablated by focusing a KrF excimer laser down to a spot size of 0.05 cm{sup 2} with a fluence of approximately 4.9 J/cm{sup 2}. After a few tens of pulses, surface irregularities (corrugations and pits) progressively emerge, with size 1--100 {micro}m which is much larger than the laser wavelength. After hundreds of laser pulses, large scale wavelike patterns, on the order of 20 {micro}m, are observed on the aluminum surface. The authors propose that these wave patterns are caused by the Kelvin-Helmholtz instability at the interface of the molten aluminum and the plasma plume. A parametric study is given in terms of the molten layer`s thickness and of the spatial extent and kinetic energy density in the laser-produced plasma plume. Also included is an estimate of the cumulative growth in a multi-pulse laser ablation experiment. These estimates indicate that the Kelvin-Helmholtz instability is a viable mechanism for the formation of the large scale structures. Once formed, these large scale surface roughness causes multiple reflections of the laser light, and may increase the absorption coefficient over a pristine, flat surface by an order of magnitude.

A novel PPAR{gamma} agonist, KR62776, suppresses RANKL-induced osteoclast differentiation and activity by inhibiting MAP kinase pathways  

SciTech Connect (OSTI)

We investigated the effects of a novel peroxisome proliferator-activated receptor {gamma} (PPAR{gamma}) agonist, KR62776, on osteoclast differentiation and function, and on the underlying signaling pathways. KR62776 markedly suppressed differentiation into osteoclasts in various osteoclast model systems, including bone marrow mononuclear (BMM) cells and a co-culture of calvarial osteoblasts and BMM cells. KR62776 suppressed the activation of tartrate-resistant acid phosphatase (TRAP) and the expression of genes associated with osteoclast differentiation, such as TRAP, dendritic cell-specific transmembrane protein (DC-STAMP), and osteoclast-associated receptor (OSCAR). Furthermore, KR62776 reduced resorption pit formation in osteoclasts, and down-regulated genes essential for osteoclast activity, such as Src and {alpha}v{beta}3 integrin. An analysis of a signaling pathway showed that KR62776 inhibited the receptor activator of nuclear factor-{kappa}B ligand (RANKL)-induced activation of p38 mitogen-activated protein kinase (p38MAPK), extracellular regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and nuclear factor-{kappa}B (NF-{kappa}B). Together, these results demonstrate that KR62776 negatively affects osteoclast differentiation and activity by inhibiting the RANKL-induced activation of MAP kinases and NF-{kappa}B.

Altering the Electrostatic Potential in the Major Groove: Thermodynamic and Structural Characterization of 7-Deaza-2;#8242;-deoxyadenosine:dT Base Pairing in DNA  

SciTech Connect (OSTI)

As part of an ongoing effort to explore the effect of major groove electrostatics on the thermodynamic stability and structure of DNA, a 7-deaza-2'-deoxyadenosine:dT (7-deaza-dA:dT) base pair in the Dickerson-Drew dodecamer (DDD) was studied. The removal of the electronegative N7 atom on dA and the replacement with an electropositive C-H in the major groove was expected to have a significant effect on major groove electrostatics. The structure of the 7-deaza-dA:dT base pair was determined at 1.1 {angstrom} resolution in the presence of Mg{sup 2+}. The 7-deaza-dA, which is isosteric for dA, had minimal effect on the base pairing geometry and the conformation of the DDD in the crystalline state. There was no major groove cation association with the 7-deaza-dA heterocycle. In solution, circular dichroism showed a positive Cotton effect centered at 280 nm and a negative Cotton effect centered at 250 nm that were characteristic of a right-handed helix in the B-conformation. However, temperature-dependent NMR studies showed increased exchange between the thymine N3 imino proton of the 7-deaza-dA:dT base pair and water, suggesting reduced stacking interactions and an increased rate of base pair opening. This correlated with the observed thermodynamic destabilization of the 7-deaza-dA modified duplex relative to the DDD. A combination of UV melting and differential scanning calorimetry experiments were conducted to evaluate the relative contributions of enthalpy and entropy in the thermodynamic destabilization of the DDD. The most significant contribution arose from an unfavorable enthalpy term, which probably results from less favorable stacking interactions in the modified duplex, which was accompanied by a significant reduction in the release of water and cations from the 7-deaza-dA modified DNA.

Direct measurement of anisotropy of interfacial free energy from grain boundary groove morphology in transparent organic metal analong systems  

SciTech Connect (OSTI)

Both academia and industry alike have paid close attention to the mechanisms of microstructural selection during the solidification process. The forces that give rise to and the principles which rule the natural selection of particular morphologies are important to understanding and controlling new microstructures. Interfacial properties play a very crucial role to the selection of such microstructure formation. In the solidification of a metallic alloy, the solid-liquid interface is highly mobile and responds to very minute changes in the local conditions. At this interface, the driving force must be large enough to drive solute diffusion, maintain local curvature, and overcome the kinetic barrier to move the interface. Therefore, the anisotropy of interfacial free energy with respect to crystallographic orientation is has a significant influence on the solidification of metallic systems. Although it is generally accepted that the solid-liquid interfacial free energy and its associated anisotropy are highly important to the overall selection of morphology, the confident measurement of these particular quantities remains a challenge, and reported values are scarce. Methods for measurement of the interfacial free energy include nucleation experiments and grain boundary groove experiments. The predominant method used to determine anisotropy of interfacial energy has been equilibrium shape measurement. There have been numerous investigations involving grain boundaries at a solid-liquid interface. These studies indicated the GBG could be used to describe various interfacial energy values, which affect solidification. Early studies allowed for an estimate of interfacial energy with respect to the GBG energy, and finally absolute interfacial energy in a constant thermal gradient. These studies however, did not account for the anisotropic nature of the material at the GBG. Since interfacial energy is normally dependent on orientation of the crystallographic plane of the solid with respect to the liquid, a better calculation of interfacial energy was needed. Herring described this orientation dependence, which related the interfacial undercooling to the principle interfacial curvatures. The present study pertains to the measurement of the anisotropy of interfacial energy by comparison of experimental and theoretical GBG geometries in pure succinonitrile (SCN) and pivalic acid (PVA). A quantity of SCN and PVA was distilled and zone refined using a process that is defined in the experimental procedure portion of this paper. Very thin (100 {micro}m) slide assemblies were created and filled with these organic materials. For each system, several grooves were photographed and their shapes were compared with theoretical predictions. The correlation between experiment and theory was quantified and plotted as a function of the anisotropy for each of the GBG's examined, and a maximum correlation corresponded to the anisotropy of interfacial energy which describes that particular rotation of the GBG. The results from several rotations were statistically analyzed to ensure confidence in the measurement of the anisotropy of interfacial energy and, finally, compared to reported values obtained with other techniques.

Kinetically tailored properties of electron-beam excited XeF(C. -->. A) and XeF(B. -->. X) laser media using an Ar-Kr buffer mixture  

SciTech Connect (OSTI)

Use of a two-component buffer gas comprised of Ar and Kr results in electron-beam excited XeF(C..-->..A) laser pulse energy and intrinsic efficiency values comparable to those of UV rare gas-halide lasers. Herein the authors report measurements of transient absorption confirming that the primary effect of a buffer comprised of Ar and Kr is a significantly lower level of ionized and excited species that absorb in the blue-green spectral region. Spectral analysis of a variety of mixtures show that the Ar-Kr buffer also benefits XeF(C..-->..A) laser performance due to an increase in gain in the 400-450 nm region caused by the presence of the Kr/sub 2/F excimer. In addition, a large increase in absorption at --351 nm, also due to Kr/sub 2/F, suppresses oscillation on the competitive XeF(B..-->..X) transition and, for certain conditions, makes efficient simultaneous oscillation of the XeF(B..-->..X) and XeF(C..-->..A) laser transitions possible.

Partial discharge pattern analysis using support vector machine to estimate size and position of metallic particle adhering to spacer in GIS  

Science Journals Connector (OSTI)

Abstract Gas insulated substations (GISs) are widely used in electrical power transmission and distribution systems. The presence of free and fixed metallic particles can initiate partial discharges (PDs) in GIS which can become a serious defect and reduce the reliability of GIS. The particle initiated PD characteristics depend on the particle size and position. Therefore, the PD characteristics can be used for the estimation of particle size and position on the spacer surface. Knowledge about the particle size and position are the important steps for the reliability improvement of the GIS equipments. This paper investigates the PD characteristics for fixed particle adhering to cylindrical shaped spacer in a simulated GIS. Length of cylindrical particles, their position on the spacer surface and gas pressure is varied to study the PD characteristics that are represented by PD fingerprints. Then these data are used for particle size and position identification. For this purpose, the use of linear support vector machine has been proposed in this paper to classify particle position and size based on the PD fingerprints data acquired at different SF6 gas pressures. It is shown that the proposed method was able to successfully estimate particles size and position at different gas pressures with an accuracy of 94%. Thus in order to improve the reliability of GIS, this approach could be considered as a potential method for particle position and size estimation in GIS.

Investigation into the failure cause of a double-acting, leading-edge-groove, tilting-pad thrust bearing. Final report, Feb-Aug 90  

SciTech Connect (OSTI)

This report describes the results of bench tests simulating operation and failure of a thrust bearing used in a gas turbine engine compressor development test rig. The bearing was a double acting, tilting pad with offset pivot, leading edge groove configuration using an AMS 4928 titanium collar and C18200 copper-chrome alloy pads with a No. 2 babbitt face. The bench tests successfully simulated the bearing failure and demonstrated a materials incompatibility. This was supported by visual examination, scanning electron microscopy and X-ray energy spectroscopy. A comparison of the bench test results to the compressor rig bearing failure is provided to support the report conclusions.

Investigation of the effects of LIFT printing with a KrF-excimer laser on thermally sensitive electrically conductive adhesives  

Science Journals Connector (OSTI)

Laser induced forward transfer is an emerging material deposition technology. We investigated the feasibility of this technique for printing thermally sensitive, electrically conductive adhesives with and without using an intermediate dynamic release layer. A 248 nm KrF-excimer laser was used to print the epoxy-based conductive adhesives containing silver flakes down to 75 ?m dot size. The process is particularly relevant for realizing electrical connections to surface mount devices in the microelectronics industry. Characterization of the printed materials was analyzed by Fourier transform infrared spectroscopy, four-point electrical measurements, die-shear testing and temperature shock testing, to establish that the properties of the adhesive were not affected by direct or indirect laser irradiation. The lack of degradation by the laser onto the adhesives confirms the potential of this technique for interconnection applications.

Two source emission behavior of projectile fragments alpha in 84^Kr interactions at around 1 GeV per nucleon  

E-Print Network [OSTI]

The emission of projectile fragments alpha has been studied in 84^Kr interactions with nuclei of the nuclear emulsion detector composition at relativistic energy below 2 GeV per nucleon. The angular distribution of projectile fragments alpha in terms of transverse momentum could not be explained by a straight and clean-cut collision geometry hypothesis of Participant - Spectator (PS) Model. Therefore, it is assumed that projectile fragments alpha were produced from two separate sources that belong to the projectile spectator region differing drastically in their temperatures. It has been clearly observed that the emission of projectile fragments alpha are from two different sources. The contribution of projectile fragments alpha from contact layer or hot source is a few percent of the total emission of projectile fragments alphas. Most of the projectile fragments alphas are emitted from the cold source.

The rare crystallographic structure of d(CGCGCG){sub 2}: The natural spermidine molecule bound to the minor groove of left-handed Z-DNA d(CGCGCG){sub 2} at 10 {sup o}C  

SciTech Connect (OSTI)

Several crystal structure analyses of complexes of synthetic polyamine compounds, including N {sup 1}-(2-(2-aminoethylamino))ethyl)ethane-1,2-diamine PA(222) and N {sup 1}-(2-(2-(2-aminoethylamino)ethylamino)ethyl)ethane-1,2-diamine PA(2222), and left-handed Z-DNA d(CGCGCG){sub 2} have been reported. However, until now, there have been no examples of naturally occurring polyamines bound to the minor groove of the left-handed Z-DNA of d(CGCGCG){sub 2} molecule. We have found that spermidine, a natural polyamine, is connected to the minor groove of left-handed Z-DNA of d(CGCGCG){sub 2} molecule in a crystalline complex grown at 10 {sup o}C. The electron density of the DNA molecule was clear enough to determine that the spermidine was connected in the minor groove of two symmetry related molecules of left-handed Z-DNA d(CGCGCG){sub 2}. This is the first example that a spermidine molecule can form a bridge conformation between two symmetry related molecules of left-handed Z-DNA d(CGCGCG){sub 2} in the minor groove.

Levels of Rb93, Sr93, and Y93 fed in the decays of Kr93, Rb93, and Sr93  

Science Journals Connector (OSTI)

The ? rays and conversion electrons following the ?- decay of Kr93, Rb93, and Sr93 have been measured by applying on-line mass-separation techniques to U235 fission products. Level schemes for the three daughter nuclei are proposed based on the study of ?-singles, ??-coincidence, and internal-conversion electron spectra. Internal-conversion coefficients were determined for 10 transitions and the deduced multipolarities as well as logft values were combined with known reaction results to assign spins and parities. The half-life for the 758.63-KeV isomeric level in Y93 was measured to be 85 ± 15 msec.RADIOACTIVITY Kr93, Rb93, Sr93; measured E?, I?, ?? coin, ICC; deduced logft, ?. Ym93; measured T12.

Detection of the primary scintillation light from dense Ar, Kr and Xe with novel photosensitive gaseous detectors  

E-Print Network [OSTI]

The detection of primary scintillation light in combination with the charge or secondary scintillation signals is an efficient technique to determine the events t=0 as well as particle / photon separation in large mass TPC detectors filled with noble gases and/or condensed noble gases. The aim of this work is to demonstrate that costly photo-multipliers could be replaced by cheap novel photosensitive gaseous detectors: wire counters, GEMs or glass capillary tubes coupled with CsI photocathodes. We have performed systematic measurements with Ar, Kr and Xe gas at pressures in the range of 1-50 atm as well as some preliminary measurements with liquid Xe and liquid Ar. With the gaseous detectors we succeeded in detecting scintillation light produced by 22 keV X-rays with an efficiency of close to 100%. We also detected the scintillation light produced by bs (5 keV deposit energy) with an efficiency close to 25%. Successful detection of scintillation from 22 keV gammas open new experimental possibilities not only ...

Effect of spacer layer thickness on multi-stacked InGaAs quantum dots grown on GaAs (311)B substrate for application to intermediate band solar cells  

Science Journals Connector (OSTI)

We have investigated the properties of multi-stacked layers of self-organized In0.4Ga0.6As quantum dots(QDs) on GaAs (311)B grown by molecular beam epitaxy. We found that a high degree of in-plane ordering of QDs structure with a six-fold symmetry was maintained though the growth has been performed at a higher growth rate than the conventional conditions. The dependence of photoluminescence characteristics on spacer layer thickness showed an increasing degree of electronic coupling between the stacked QDs for thinner spacer layers. The external quantum efficiency for an InGaAs/GaAs quantum dotsolar cell (QDSC) with a thin spacer layer thickness increased in the longer wavelength range due to additive contribution from QD layers inserted in the intrinsic region. Furthermore a photocurrent production by 2-step photon absorption has been observed at room temperature for the InGaAs/GaAs QDSC with a spacer layer thickness of 15?nm.

Development of a Silicon Based Electron Beam Transmission Window for Use in a KrF Excimer Laser System  

SciTech Connect (OSTI)

The Princeton Plasma Physics Laboratory (PPPL), in collaboration with the Naval Research Laboratory (NRL), is currently investigating various novel materials (single crystal silicon, <100>, <110> and <111>) for use as electron-beam transmission windows in a KrF excimer laser system. The primary function of the window is to isolate the active medium (excimer gas) from the excitation mechanism (field-emission diodes). Chosen window geometry must accommodate electron energy transfer greater than 80% (750 keV), while maintaining structural integrity during mechanical load (1.3 to 2.0 atm base pressure differential, approximate 0.5 atm cyclic pressure amplitude, 5 Hz repetition rate) and thermal load across the entire hibachi area (approximate 0.9 W {center_dot} cm superscript ''-2''). In addition, the window must be chemically resistant to attack by fluorine free-radicals (hydrofluoric acid, secondary). In accordance with these structural, functional, and operational parameters, a 22.4 mm square silicon prototype window, coated with 500 nm thin-film silicon nitride (Si{sub 3}N{sub 4}), has been fabricated. The window consists of 81 square panes with a thickness of 0.019 mm {+-} 0.001 mm. Stiffened (orthogonal) sections are 0.065 mm in width and 0.500 mm thick (approximate). Appended drawing (Figure 1) depicts the window configuration. Assessment of silicon (and silicon nitride) material properties and CAD modeling and analysis of the window design suggest that silicon may be a viable solution to inherent parameters and constraints.

Raman-shifted KrF laser radiation with low amplified spontaneous emission for a rotational Raman daytime-temperature lidar  

SciTech Connect (OSTI)

Various configurations of a tunable two-stage KrF laser have been investigated for providing powerful laser pulses with very low amplified spontaneous emission (ASE). The lowest fraction (0.00017%) of ASE was attained with a single-pass amplifier and a phase-conjugate Brillouin mirror. The most suitable application envisaged for the laser source, i.e., remote daytime-temperature measurement by means of rotational Raman scattering, is a dedicated oscillator--amplifier configuration with an ASE of 0.005% at an output of 300 mJ. The very low values of ASE were measured with the aid of a thallium atomic-vapor filter.

Application of a high-power KrF laser for the study of supersonic gas flows and the development of hydrodynamic instabilities in layered media  

SciTech Connect (OSTI)

The design of a miniature laser shock tube for the study of a wide range of hydrodynamic phenomena in liquids at pressures greater than 10 kbar and in supersonic flows with large Mach numbers (greater than 10) is discussed. A substance filling a chamber of quadratic cross section, with a characteristic size of several centimetres, is compressed and accelerated due to local absorption of 100 ns, 100 J KrF laser pulses near the entrance window. It is proposed to focus a laser beam by a prism raster, which provides a uniform intensity distribution over the tube cross section. The system can be used to study the hypersonic flow past objects of complex shape and the development of hydrodynamic instabilities in the case of a passage of a shock wave or a compression wave through the interfaces between different media.

Nonlinear-optical processes in the near-resonant two-photon excitation of xenon by femtosecond KrF-excimer-laser pulses  

Science Journals Connector (OSTI)

The nonlinear response of xenon gas due to a near-resonant two-photon excitation at the 5p6 1S0?6p[1/2]0 transition with a femtosecond KrF-excimer-laser system is investigated for the intensity range 1010–1015 W/cm2. Stimulated hyper-Raman scattering and amplified spontaneous emission of atomic xenon are observed at wavelengths around 823 and 828 nm. These emissions are superimposed by four-wave parametric-oscillation processes leading to strong ultrashort continuum radiation in the visible and near-infrared (650–850 nm), uv (185–400 nm), and vacuum ultraviolet (147–155 nm) spectral ranges with output powers up to 100 MW. From difference-frequency-mixing experiments microscopic nonlinear susceptibilities in the range of ??(3)?=10-48 to 10-50 m5/V2 have been determined, which are in good agreement with calculations.

First result of the experimental search for the 9.4 keV solar axion reactions with Kr-83 in the copper proportional counter  

E-Print Network [OSTI]

The experimental search for solar hadronic axions is started at the Baksan Neutrino Observatory of the Institute for Nuclear Researches Russian Academy of Science. It is assumed that axions are created in the Sun during M1-transition between the first thermally excited level at 9.4 keV and the ground state in Kr-83. The experiment is based on axion detection via resonant absorption process by the same nucleus in the detector. The big copper proportional counter filled with krypton is used to detect signals from axions. The experimental setup is situated in the deep underground low background laboratory. No evidence of axion detection were found after the 26.5 days data collection. Resulting new upper limit on axion mass is m_{A} < 130 eV at 95% C.L.

Production of extended plasma channels in atmospheric air by amplitude-modulated UV radiation of GARPUN-MTW Ti : sapphire-KrF laser. Part 1. Regenerative amplification of subpicosecond pulses in a wide-aperture electron beam pumped KrF amplifier  

SciTech Connect (OSTI)

Regenerative amplification of single and multiple ultrashort subpicosecond UV pulses in a wide-aperture KrF amplifier with an unstable confocal resonator was investigated on the GARPUN-MTW hybrid laser system. Amplitude-modulated 100-ns long UV radiation pulses with an energy of several tens of joules were obtained at the output of the system. The pulses were a combination of a quasi-stationary oscillation pulse and a train of amplified ultrashort pulses (USPs) with a peak power of 0.2-0.3 TW, which exceeded the power of free-running lasing pulse by three orders of magnitude. The population inversion recovery time in the active KrF laser medium was estimated: {tau}{sub c} {<=} 2.0 ns. Trains of USPs spaced at an interval {Delta}t Almost-Equal-To {tau}{sub c} were shown to exhibit the highest amplification efficiency. The production of amplitude-modulated UV pulses opens up the way to the production and maintenance of extended plasma channels in atmospheric air. (extreme light fields and their applications)

Production of extended plasma channels in atmospheric air by amplitude-modulated UV radiation of GARPUN-MTW Ti : sapphire-KrF laser. Part 2. Accumulation of plasma electrons and electric discharge control  

SciTech Connect (OSTI)

The problem of the production of extended ({approx}1 m) plasma channels is studied in atmospheric air by amplitude-modulated laser pulses of UV radiation, which are a superposition of a subpicosecond USP train amplified in a regenerative KrF amplifier with an unstable confocal resonator and a quasi-stationary lasing pulse. The USPs possess a high (0.2-0.3 TW) peak power and efficiently ionise oxygen molecules due to multiphoton ionisation, and the quasi-stationary lasing pulse, which has a relatively long duration ({approx}100 ns), maintains the electron density at a level n{sub e} = (3-5) Multiplication-Sign 10{sup 14} cm{sup -3} by suppressing electron attachment to oxygen. Experiments in laser triggering of high-voltage electric discharges suggest that the use of combined pulses results in a significant lowering of the breakdown threshold and enables controlling the discharge trajectory with a higher efficiency in comparison with smooth pulses. It was shown that controlled breakdowns may develop with a delay of tens of microseconds relative to the laser pulse, which is many orders of magnitude greater than the lifetime of free electrons in the laser-induced plasma. We propose a mechanism for this breakdown, which involves speeding-up of the avalanche ionisation of the air by negative molecular oxygen ions with a low electron binding energy ({approx}0.5 eV) and a long lifetime ({approx}1 ms), which are produced upon cessation of the laser pulse.

Rotational Transition of Incommensurate Kr Monolayers on Graphite  

Science Journals Connector (OSTI)

Synchrotron x-ray diffraction studies of the orientational epitaxy of krypton on single-crystal graphite are reported. The system displays a continuous transition from an aligned to a rotated orientation with increasing mean misfit in a manner predicted by a hexagonal-domain-wall model of the weakly incommensurate phase. A hysteresis at the critical misfit is observed. The results are discussed in light of current views of the structure of the incommensurate phase.

Depinning of Atomically Thin Kr Films on Gold  

Science Journals Connector (OSTI)

We have employed the quartz-crystal microbalance technique to measure the sliding friction of krypton films physisorbed on gold. By slowly increasing the amplitude of the substrate oscillations, we have observed a sharp transition from a film locked to the substrate to a sliding one. This transistion is characterized by hysteresis both in dissipation and inertial mass as the amplitude is decreased. Finally, the dependence of this transition on film coverage has been studied in some detail.

Resonances in the Photoionization Continuum of Kr and Xe  

Science Journals Connector (OSTI)

A total of 153 krypton resonances in the spectral region 500-337 Ĺ, and 254 xenon resonances in the spectral region 600-375 Ĺ are reported. The disposition of the detailed line lists are indicated. The analysis is very incomplete and will require detailed theoretical calculations to advance. In krypton, 45 resonances and in xenon, 56 resonances have been grouped into probable Rydberg series, for which classifications are suggested. In general, the resonances observed are due to the excitation of the inner subshell "s" electron (ns2np6?nsnp6mp) or to the excitation of two of the outer electrons simultaneously (ns2np6?ns2np4mll?). These highlying excited states autoionize, resulting in resonances with window-, asymmetric-, and absorption-type profiles. The detailed lists for the subshell "s" electron excitations are given.

Population trapping in Kr and Xe in intense laser fields  

Science Journals Connector (OSTI)

We have observed trapping of population in Rydberg states of atoms and ions exposed to intense laser radiation. The trapping occurs in nonstationary ‘‘wave-packet’’ superposition states, created, via ac Stark-shifted multiphoton resonances during the laser pulse. The formation of these highly excited bound states requires the nonresonant absorption of up to 20 or more photons; some of the ionic Rydberg states lie nearly 32 eV above the ionic ground state. All of the trapped states having binding energies much less than the photon energy but remain stable against ionization even when the multiphoton ionization probability of the atom is saturated.

High-pressure EXAFS measurements of solid and liquid Kr  

Science Journals Connector (OSTI)

X-ray-absorption measurements of liquid and solid krypton at room temperature in the pressure range 0.1–30 GPa have been performed using the dispersive setup and diamond-anvil cells as a pressure device. The evolution of the near-edge structures as a function of pressure, including the first intense resonance, has been interpreted using multiple-scattering calculations. It is shown that the near-edge structures are reproduced taking into account two-body and three-body terms associated with the first-neighbor atoms. Extended x-ray-absorption fine-structure (EXAFS) spectra have been analyzed in the framework a multiple-scattering data-analysis approach taking proper account of the atomic background including the [1s4p], [1s3d], and [1s3p] double-electron excitation channels. Isobaric Monte Carlo (MC) computer simulations based on empirical pair potentials, as proposed by Barker (K2) and Aziz (HFD-B), have been performed to make a quantitative comparison of theoretical and experimental local structural details of condensed krypton at high pressures. From the analysis of EXAFS data we were able to obtain simultaneous information on average distance, width, and asymmetry of the first-neighbor distribution, as a function of pressure. These parameters yield a unique insight on the potential function because they are affected by both minimum position and curvature of the effective pair potential. The trend of the first-neighbor distribution as a function of pressure is in quantitative agreement with the HFD-B potential at moderate pressures, deviations are found at higher pressures where EXAFS spectra are very sensitive to the hard-core repulsive part of the potential. The weak EXAFS signal of liquid krypton at room temperature and 0.75 GPa has been found in accord with the results of the MC simulations within the noise of the measurement. © 1996 The American Physical Society.

Bent crystal analyzer without grooves for inelastic scattering -- first experimental results  

SciTech Connect (OSTI)

A new design of a bent crystal analyzer for high energy resolution inelastic X-ray scattering has been recently proposed. It has been theoretically predicted that an analyzer with reflecting planes at a certain angle with respect to a crystal surface, bent with two different radii of curvature, will have the same energy resolution as a perfect crystal. The first experimental measurement obtained at the Advanced Photon Source of a bandwidth of such an analyzer is presented. The overall energy resolution of the analyzer and monochromator observed with a narrow beam is equal to 16.4 meV (FWHM) at 13.84 KeV.

Controllable 0 ? ? transition in iron pnictide superconductor junctions with a spacer of strong ferromagnet  

SciTech Connect (OSTI)

We investigate the control of 0?? transition in Josephson junctions consisting of a highly spin-polarized ferromagnet coupled to two iron pnictide superconductors (SCs). It is shown that, a 0?? transition as a function of interband coupling strength is always exhibited, which can be experimentally used to discriminate the s{sub ±}-wave pairing symmetry in the iron pnictide SCs from the s{sub ++}-wave one in MgB{sub 2}. By tuning the doping level in the s{sub ±}-wave SCs, one can vary the interband coupling strength so as to obtain the controllable 0?? transition. This device may be realized with current technologies and has practical use in Cooper pair spintronics and quantum information.

Elastic scattering of low-energy electrons by Ne, Ar, Kr, and Xe  

Science Journals Connector (OSTI)

We treat low-energy electron scattering by atoms within a Kohn-Sham-type one-particle theory. In applying this theory, all many-body effects involved in the projectile-target interaction are absorbed into a one-particle potential. Hence, one merely has to solve an elementary potential-scattering problem. However, there are two crucial points to be observed in the construction of the scattering potential. (1) The Kohn-Sham-type exchange-correlation potential must be formed by using correlation factors which are required to have certain asymptotic and integral properties. (2) Since the scattering process is viewed as being quasistationary, the unbound projectile state must be modified by a bell-jar-type envelope function to account for the effect of a finite residence time in the target where the projectile causes a finite perturbation. During this time the entire system has to be treated as consisting of N+1 indistinguishable electrons which in a Kohn-Sham-type theory are described by only N+1 self-consistent one-particle states. Once the analytical forms of the correlation factors and the envelope function have been chosen, the calculational procedure is completely parameter-free. Although it is considerably simpler than well-established methods in this field, it provides comparably good results on differential cross sections and scattering-induced polarizations in a wide range of impact energies (5–100 eV).

Effect of molecular solutes on the electron drift velocity in liquid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

Measurements of the electron drift velocity in liquid argon, krypton, and xenon were performed in an electric field up to 100 kV cm-1. At higher field strengths saturation velocities were observed in agreement with other authors. The addition of a small concentration of molecular solutes leads to an increase of the electron drift velocity above the saturation value of the pure liquid. The drift velocity either reaches a higher constant value or passes through a maximum at field strengths greater than 104 V cm-1. This effect was investigated as a function of solute concentration for N2, H2, methane, ethane, propane, and butane. Inelastic energy losses in collisions of electrons and solute molecules are assumed and by means of the Cohen-Lekner theory the energy dependence of the loss processes is derived.

Elastic scattering of electrons from Ar and Kr in the second-order eikonal approximation  

Science Journals Connector (OSTI)

We report the first application of Baker's second-order eikonal approximation (SOEA) to atomic collisions and compare the predictions of SOEA with those of Glauber's first-order eikonal approximation (FOEA). The SOEA takes into account amplitude modulation, in addition to phase modulation of the incoming plane wave. In the case of elastic scattering of electrons from argon and krypton, it is found that the second-order correction term influences to a large extent the angular distribution of scattered electrons. In the intermediate-and high-energy range it is seen that the SOEA gives much better agreement than the FOEA with the staticfield calculation of Fink and Yates.

Electron emission due to positronium annihilation in solid Ar, Kr, and Xe  

Science Journals Connector (OSTI)

We present measurements of positron and electron emission by solid rare-gas surfaces implanted with low-energy positrons. The electron yield exhibits a 0.5-eV-wide peak at a positron energy just above the threshold for positronium (Ps) formation, but below the electron-hole–pair threshold. A similar peak in the fraction of the incident positrons annihilating in the sample leads us to conclude that (1) slow Ps has an anomalously short diffusion length possibly due to self-trapping, and (2) energetic electrons are liberated from Ps atoms following annihilation of the positrons with valence electrons. The energy spectrum of the emitted electrons should contain information about the internal Ps wave function in the solids.

Ioniclike energy structure of neutral core-excited states in free Kr clusters  

Science Journals Connector (OSTI)

The development of electronic states in krypton clusters is investigated by high-resolution core-level electron spectroscopy. The energy ordering of bulk versus surface 3d?1np(n>5) core-excited states in neutral clusters is demonstrated to be reversed to the 3d?15p level situation. The cluster 3d?16p,7p states are proven to be at a lower energy than the corresponding atomic levels. These findings reveal the ioniclike energy structure of the neutral cluster core-excited levels. The phenomenon is explained by a spatial spread of the excited orbitals over the cluster lattice.

Novel Use of Water Soluble "Aquapour" As A Temporary Spacer During Coil Winding For The NSTX-U Centerstack  

SciTech Connect (OSTI)

A major facility upgrade to the National Spherical Torus eXperiment (NSTX-U) is currently underway at Princeton Plasma Physics Laboratory (PPPL). A key component of NSTX-U is the fabrication of a new, higher field centerstack (CS). In order to simultaneously provide robust joints between the inner and outer legs of the Toroidal Field Coils (TF) and minimize radial build, the NSTX-U CS design requires that the Ohmic Heating solenoid (OH) be wound directly on the inner TF bundle. To protect the OH against thermal expansion stress during scenarios where the inner TF bundle is hot but the OH is relatively cool, the completed CS will have a 0.100 inch annular gap between the outer diameter of the TF bundle and the inner diameter of the OH solenoid. "Aquapour", a proprietary material produced by the Advanced Ceramics Manufacturing Company will be used during manufacture to produce this gap. After the TF bundle is vacuum pressure impregnated and cured, a cylindrical "clam shell" mold will be assembled around it, and a slurry of powdered Aquapour and water will be pumped into the annular space between the mold and TF bundle. Subsequent baking will turn the Aquapour solid, and a protective layer of wet lay-up fiberglass and resin will be added. The OH solenoid will be wound directly on this wet lay-up shell. After vacuum pressure impregnation of the OH, the water soluble Aquapour will be washed away, leaving the required radial clearance between the TF and OH. This paper will describe prototyping and testing of this process, and plans for use on the actual CS fabrication.

Development of fast cooling pulsed magnets at the Wuhan National High Magnetic Field Center  

SciTech Connect (OSTI)

Pulsed magnets with fast cooling channels have been developed at the Wuhan National High Magnetic Field Center. Between the inner and outer sections of a coil wound with a continuous length of CuNb wire, G10 rods with cross section 4 mm × 5 mm were inserted as spacers around the entire circumference, parallel to the coil axis. The free space between adjacent rods is 6 mm. The liquid nitrogen flows freely in the channels between these rods, and in the direction perpendicular to the rods through grooves provided in the rods. For a typical 60 T pulsed magnetic field with pulse duration of 40 ms, the cooling time between subsequent pulses is reduced from 160 min to 35 min. Subsequently, the same technology was applied to a 50 T magnet with 300 ms pulse duration. The cooling time of this magnet was reduced from 480 min to 65 min.

We present a laser-target scaling model which permits approximate prediction of the dependence of ablation pressure, mechanical coupling coefficient, and related parameters in vacuum upon single-pulse laser intensity (I), wavelength (lambda), and pulse width (tau) over extremely broad ranges. We show that existing data for vacuum mechanical coupling coefficient for metallic and endothermic nonmetallic, surface-absorbing planar targets follows this empirical trend to within a factor of 2 over 7 orders of magnitude in the product (Ilambda(tau)/sup 1/2/). The comparison we present is valid for intensity equal to or greater than the peak-coupling intensity I/sub max/, where dense

These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and various laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels. 35 figs.

Conformal growth of Mo/Si multilayers on grating substrates using collimated ion beam sputtering  

SciTech Connect (OSTI)

Deposition of multilayers on saw-tooth substrates is a key step in the fabrication of multilayer blazed gratings (MBG) for extreme ultraviolet and soft x-rays. Growth of the multilayers can be perturbed by shadowing effects caused by the highly corrugated surface of the substrates, which results in distortion of the multilayer stack structure and degradation of performance of MBGs. To minimize the shadowing effects we used an ionbeam sputtering machine with a highly collimated atomic flux to deposit Mo/Si multilayers on saw-tooth substrates. The sputtering conditions were optimized by finding a balance between smoothening and roughening processes in order to minimize degradation of the groove profile in the course of deposition and at the same time to keep the interfaces of a multilayer stack smooth enough for high efficiency. An optimal value of energy of 200 eV for sputtering Kr{sup +} ions was found by deposition of test multilayers on flat substrates at a range of ion energies. Two saw-tooth substrates were deposited at energies of 200 eV and 700 eV for the sputtering ions. It was found that reduction of the ion energy improved the blazing performance of the MBG and resulted in a 40% gain in the diffraction efficiency due to better replication of the groove profile by the multilayer. As a result of the optimization performed, an absolute diffraction efficiency of 28.8% was achieved for the 2nd blaze order of the MBG with a groove density of 7350 lines/mm at a wavelength of 13.5 nm. Details of the growth behavior of the multilayers on flat and saw-tooth substrates are discussed in terms of the Linear Continuous Model of film growth.

Giant magnetoresistive structures based on CrO{sub 2} with epitaxial RuO{sub 2} as the spacer layer  

SciTech Connect (OSTI)

Epitaxial ruthenium dioxide (RuO{sub 2})/chromium dioxide(CrO{sub 2}) thin film heterostructures have been grown on (100)-TiO{sub 2} substrates by chemical vapor deposition. Both current-in-plane (CIP) and current-perpendicular-to-plane (CPP) giant magnetoresistive stacks were fabricated with either Co or another epitaxial CrO{sub 2} layer as the top electrode. The Cr{sub 2}O{sub 3} barrier, which forms naturally on CrO{sub 2} surfaces, is no longer present after the RuO{sub 2} deposition, resulting in a highly conductive interface that has a resistance at least four orders of magnitude lower. However, only very limited magnetoresistance (MR) was observed. Such low MR is due to the appearance of a chemically and magnetically disordered layer at the CrO{sub 2} and RuO{sub 2} interfaces when Cr{sub 2}O{sub 3} is transformed into rutile structures during its intermixing with RuO{sub 2}.

High-resolution x-ray-emission study of 1s4p and 1s3d two-electron photoexcitations in Kr  

Science Journals Connector (OSTI)

High-energy-resolution photoexcited KN2,3 x-ray-emission measurements were carried out on krypton with the excitation energy tuned around the 1s4p and 1s3d double-excitation thresholds. Comprehensive two-dimensional resonant inelastic x-ray-scattering maps were recorded for the range of excitation and emission energies corresponding to both types of double excitations. The double-excitation signal could be clearly resolved from the dominant 1s ionization signal. The latter was subtracted from the measured maps, yielding isolated 1s4p and 1s3d photoexcitation spectra. Both two-electron excitation spectra are well described by a model spectrum built of consecutive bound-bound discrete transitions and shake-up and shake-off channels giving precise energies and intensities of the corresponding contributions. The obtained results are compared with other existing experimental values based on x-ray-absorption measurements and theoretical predictions.

A series of novel metal–organic coordination polymers constructed from the new 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole spacer and aromatic carboxylates: Synthesis, crystal structures, and luminescence properties  

SciTech Connect (OSTI)

Using bifunctional organic ligand 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole (HL) and different aromatic carboxylates as secondary ligands, four novel metal-organic coordination polymers, [Zn(L)(1,4-bdc){sub 0.5}] (1), [Zn{sub 1.5}(L)(2,5-pydc)] (2), [Zn(HL)(1,2,4,5-btec){sub 0.5}] (3), and [Cd(HL)(1,2,4,5-btec){sub 0.5}] (4) (1,4-bdc, 1,4-benzenedicarboxylate; 2,5-pydc, 2,5-pyridinedicarboxylate; 1,2,4,5-btec, 1,2,4,5-benzenetetracarboxylate) have been successfully synthesized and analyzed. Compound 1 features the 2D [Zn(L)]{sub n} layers built by ?{sub 3}-L bridging ligands and Zn(II) ions, which are further linked by pillared 1,4-bdc{sup 2?} ligands to form a 2-fold interpenetrating dmc framework. The 3D network of compound 2 can be simplified as a rare 2-nodal (3,6)-connected rtl (rutile) topology. Compound 3 possesses a 2D layer structure which is accomplished by connecting ladder-chains to L ligands. Compound 4 exhibits 2D [Cd(1,2,4,5-btec)] layers with infinite Cd–O–Cd rods and the adjacent 2D networks are further pillared by L with terminal bidentate coordination mode to generate the final 3D structure. The solid-state luminescent studies show that compounds 1–4 display intense fluorescent emissions. - Graphical abstract: Using bifunctional organic ligand 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole (HL) and different aromatic carboxylates as secondary ligands, four novel metal-organic coordination polymers have been obtained. All compounds show good luminescence properties at room temperature. Display Omitted - Highlights: • Four Zn(II)/Cd(II)-MOCPs have been successfully prepared with the rigid bifunctional ligand 5-(4-imidazol -1-yl-phenyl) -2H-tetrazole and different aromatic carboxylates mixed ligands. • Compound 2 is a 2-nodal rtl (rutile) net and compound 4 is a binodal (5, 6)-connected net with yav topology. • Compounds 1-4 display intense fluorescent emissions at room temperature.

Window Technologies: Low Conductance Spacers Window Technologies: Low Conductance Spacers Spacers The lites of glass in an insulating unit must be held apart at the appropriate distance by spacers. In addition to keeping the glass lites separated, the spacer system must serve a number of functions: accommodate stress induced by thermal expansion and pressure differences; provide a moisture barrier that prevents passage of water or water vapor that would fog the unit; provide a gas-tight seal that prevents the loss of any special low-conductance gas in the air space; create an insulating barrier that reduces the formation of interior condensation at the edge. Spacers The standard solution for insulating glass units (IGUs) is the use of metal spacers and sealants. These spacers, typically aluminum, also

Internal electrolyte supply system for reliable transport throughout fuel cell stacks  

DOE Patents [OSTI]

An improved internal electrolyte supply system in a fuel cell stack employs a variety of arrangements of grooves and passages in bipolar plates of the multiplicity of repeating fuel cells to route gravity-assisted flowing electrolyte throughout the stack. The grooves route electrolyte flow along series of first paths which extend horizontally through the cells between the plates thereof. The passages route electrolyte flow along series of second paths which extend vertically through the stack so as to supply electrolyte to the first paths in order to expose the electrolyte to the matrices of the cells. Five different embodiments of the supply system are disclosed. Some embodiments employ wicks in the grooves for facilitating transfer of the electrolyte to the matrices as well as providing support for the matrices. Additionally, the passages of some embodiments by-pass certain of the grooves and supply electrolyte directly to other of the grooves. Some embodiments employ single grooves and others have dual grooves. Finally, in some embodiments the passages are connected to the grooves by a step which produces a cascading electrolyte flow.

Role of shocks and mix caused by capsule defects  

SciTech Connect (OSTI)

An Eulerian code with a turbulent mix model is used to model a set of plastic (CH) ablator capsules with and without equatorial grooves. The 'perfect' capsule results were used to calibrate simulations of capsules with equatorial grooves of different depths that provided information on increasingly perturbed implosions. Simulations with a turbulence model were able to calculate the same yield over mix (YOM) ratio (experiment/mix simulation) of 0.2 to 0.3 for thin (8-{mu}m thick) and thick shell (15-{mu}m thick) capsules with no grooves and thin capsules with shallow grooves. When the capsules have deep grooves, the YOM ratio increases to greater than unity, probably because the deformed shocks focus too strongly on the symmetry axis in our two-dimensional simulations. This is supported by a comparison of simulated and experimental x-ray images.

Upgrade of the Resonance Ionization Mass Spectrometer for Precise Identification of Failed Fuel in a Fast Reactor  

SciTech Connect (OSTI)

Isotopic analysis of krypton (Kr) and xenon (Xe) by resonance ionization mass spectrometry (RIMS) is an effective tool for identification of failed fuel in fast reactors to achieve their safety operation and high plant availability. Reliability of the failed fuel detection and location (FFDL) system depends on the precise determination of {sup 78}Kr/{sup 80}Kr, {sup 82}Kr/{sup 80}Kr and {sup 126}Xe/{sup 129}Xe isotopic ratios, which is mainly hampered by statistical errors for detection of the corresponding isotopes except {sup 82}Kr generated in large amounts during operation of fast reactors. In this paper, we report on improvements of the laser optical system of our spectrometer to increase the resonance ionization efficiency of Kr and Xe atoms, focusing on (i) utilization of the uniform YAG laser beam to improve the wavelength conversion efficiency of sum frequency generation and (ii) reflection of the ultraviolet light by a concave mirror to increase the photon density. The results indicate that our upgraded resonance ionization mass spectrometer has enough performance for isotopic analysis of Kr and Xe required in the Monju FFDL system.

Low-cost laser diode array  

DOE Patents [OSTI]

A substrate is used to fabricate a low-cost laser diode array. A substrate is machined from an electrically insulative material that is thermally conductive, or two substrates can be bonded together in which the top substrate is electrically as well as thermally conductive. The substrate thickness is slightly longer than the cavity length, and the width of the groove is wide enough to contain a bar and spring (which secures the laser bar firmly along one face of the groove). The spring also provides electrical continuity from the backside of the bar to the adjacent metalization layer on the laser bar substrate. Arrays containing one or more bars can be formed by creating many grooves at various spacings. Along the groove, many bars can be adjoined at the edges to provide parallel electrical conduction. This architecture allows precise and predictable registration of an array of laser bars to a self-aligned microlens array at low cost.

Investigation of dose uniformity on the inner races of bearings treated by plasma immersion ion implantation  

Science Journals Connector (OSTI)

Plasma immersion ion implantation(PIII) is an effective technique for the surface modification of industrial components possessing an irregular shape. We have recently used PIII to treat a real industrial ball bearing to enhance the surface properties of the race surface on which the balls roll. The implantation dose uniformity along the groove is assessed using theoretical simulation and experiments. The two sets of results agree very well showing larger doses near the center. However the highest dose is not observed at the bottom or center of the groove but rather offset toward the side close to the sample platen when the bearing is placed horizontally. The minimum dose is observed near the edge or corner of the groove and our model indicates that it is due to the more glancing ion incidence as a result of the evolution of the ion sheath near the corner. The dose nonuniformity along the groove surface is about 40% based on our experimental data.

Wave guide impedance matching method and apparatus  

DOE Patents [OSTI]

A technique for modifying the end portion of a wave guide, whether hollow or solid, carrying electromagnetic, acoustic or optical energy, to produce a gradual impedance change over the length of the end portion, comprising the cutting of longitudinal, V-shaped grooves that increase in width and depth from beginning of the end portion of the wave guide to the end of the guide so that, at the end of the guide, no guide material remains and no surfaces of the guide as modified are perpendicular to the direction of energy flow. For hollow guides, the grooves are cut beginning on the interior surface; for solid guides, the grooves are cut beginning on the exterior surface. One or more resistive, partially conductive or nonconductive sleeves can be placed over the exterior of the guide and through which the grooves are cut to smooth the transition to free space.

Decay Energies of Gaseous Fission Products and their Daughters for A=88 to 93  

Science Journals Connector (OSTI)

A systematic study of ?-decay energies has been made for mass-separated activities of Kr gaseous fission products and their daughters at the TRISTAN on-line separator facility at the Ames Laboratory research reactor. A well-type plastic scintillator was used in coincidence with a Ge(Li) ? detector to determine ?-group end-point energies and deduce Q values. The following ?-decay energies have been determined: Kr88, 2.93 ± 0.03 MeV; Rb88, 5.30 ± 0.06 MeV; Kr89, 4.93 ± 0.06 MeV; Kr90, 4.35 ± 0.05 MeV; Rb90, 6.32 ± 0.07 MeV; Kr91, 6.12 ± 0.07 MeV; Rb91, 5.68 ± 0.04 MeV; Kr92, 5.97 ± 0.08 MeV; Rb92, 7.58 ± 0.15 MeV; Sr92, 1.93 ± 0.03 MeV; Kr93, 8.3 ± 0.5 MeV; and Rb93, 7.23 ± 0.10 MeV. The decay energies are compared with previous measurements, systematics predictions, and two currently accepted mass relations. The energies are used to predict the ?-decay energies for 13 additional nuclei by means of systematics.

The decay of the mass-separated, very neutron-rich isotope 93Br has been studied by ? spectroscopy. A level scheme of its daughter 93Kr has been constructed. Level energies, ?-ray branching ratios, and multipolarities suggest spins and parities which are in accord with a smooth systematics of the N=57 isotones for Z<~40, suggesting the N=56 subshell closure still to be effective in Kr isotopes. So far, there is no indication of a progressive onset of deformation in neutron-rich Kr isotopes.

Compact vacuum insulation  

DOE Patents [OSTI]

An ultra-thin compact vacuum insulation panel is comprised of two hard, but bendable metal wall sheets closely spaced apart from each other and welded around the edges to enclose a vacuum chamber. Glass or ceramic spacers hold the wall sheets apart. The spacers can be discrete spherical beads or monolithic sheets of glass or ceramic webs with nodules protruding therefrom to form essentially "point" or "line" contacts with the metal wall sheets. In the case of monolithic spacers that form "line" contacts, two such spacers with the line contacts running perpendicular to each other form effectively "point" contacts at the intersections. Corrugations accommodate bending and expansion, tubular insulated pipes and conduits, and preferred applications are also included.

Space effect on liquid film flow in a BWR fuel bundle  

SciTech Connect (OSTI)

Critical power at boiling transition is an important factor in a boiling water reactor (BWR) fuel bundle design. Boiling transition under high quality accounts for dryout as the result of the complete disappearance of film flow on a fuel rod. This liquid film vanishing process can be calculated by the liquid film model, which takes into account the evaporation due to heat from the rod surface, liquid film entrainment by steam flow, and liquid droplet deposition. It is known that spacers affect liquid film entrainment and liquid droplet deposition, so the detailed study of spacer effects on hydrodynamic characteristics is necessary for critical power prediction based on the film flow model. Many studies have been conducted to examine spacer effects on liquid film flow. However, most of them are restricted to simple test sections such as a rectangular conduit. There are a few reports on fuel bundle geometry; however the bundle studied was only a 3 by 3 rod array. It is known that spacers affect not only deposition and entrainment but also flow distribution among the subchannels. Therefore, in this research, liquid film thickness measurements were performed to clarify the deposition and entrainment at a spacer in a full-sized fuel bundle. Furthermore, critical power predictions on a BWR fuel bundle were carried out with a film flow model that included a spacer model.

Debris-less method and apparatus for forming apertures in hollow metallic articles  

DOE Patents [OSTI]

This invention is a method for forming an aperture in a wall of a hollow metallic article without introducing metallic debris therein. In a typical operation, an annular groove is formed in an exterior portion of the wall. The groove defines an annular wall segment, and the bottom of the groove is shaped to slope downwardly away from the segment to form a tapered annular web which connects the segment to the wall. Any suitable coupling is attached to the outer face of the segment, as by welding. Pull then is applied to the coupling to effect circumferential breakage of the web, thus forming a removable single-piece wall fragment consisting of the web and segment. The fragment and the coupling member attached thereto then are removed from the wall.

Methods for the Precise Locating and Forming of Arrays of Curved Features into a Workpiece  

DOE Patents [OSTI]

Methods for manufacturing high precision arrays of curved features (e.g. lenses) in the surface of a workpiece are described utilizing orthogonal sets of inter-fitting locating grooves to mate a workpiece to a workpiece holder mounted to the spindle face of a rotating machine tool. The matching inter-fitting groove sets in the workpiece and the chuck allow precisely and non-kinematically indexing the workpiece to locations defined in two orthogonal directions perpendicular to the turning axis of the machine tool. At each location on the workpiece a curved feature can then be on-center machined to create arrays of curved features on the workpiece. The averaging effect of the corresponding sets of inter-fitting grooves provide for precise repeatability in determining, the relative locations of the centers of each of the curved features in an array of curved features.

Single crystal growth and formation of defects in deuterium-tritium layers for inertial confinement nuclear fusion  

SciTech Connect (OSTI)

We identify vapor-etched grain boundary grooves on the solid-vapor interface as the main source of surface roughness in the deuterium-tritium (D-T) fuel layers, which are solidified and then cooled. Current inertial confinement fusion target designs impose stringent limits to the cross-sectional area and total volume of these grooves. Formation of these grain boundaries occurs over time scales of hours as the dislocation network anneals and is inevitable in a plastically deformed material. Therefore, either cooling on a much shorter time scale or a technique that requires no cooling after solidification should be used to minimize the roughness.

SciTech Connect (OSTI)

A blast furnace taphole drill has a flaring head with cutting edges at its cutting end formed by intersecting angled faces. A central bore carries cleaning air to the cutting end. To prevent blockage of the cleaning air bore by debris and possible jamming of the drill, the head has deep radial grooves formed at the bottoms of the valley shapes between the cutting edges. The grooves extend radially from the air bore and conduct the air so that it can get behind or under jammed debris. Reduced taphole drilling times can be achieved.

New coil end design for the RHIC Arc dipole  

SciTech Connect (OSTI)

To simplify production, the number of parts in the ends, about 64 in each coil end, was reduced by using thicker spacers between the turns, to about 23. A new computer program was written which gives a description of each turn closely resembling the turn as made. The output of this program is processed by newly written computer programs which change the parts descriptions into forms which are used by a computer-controlled, 5-axis milling machine. The solid spacers replace spacers assembled from laminations and improve the fit as well. The parts will be molded during production. The calculated harmonic content of the ends is compared with measurements on the first magnets built with the new ends.
