Abstract

We investigate the role of lifetime effects in femtoscopy at RHIC. We find the long emission durations do not necessarily lead to large outward radii. Within the Core-Halo model, we show that resonance induced halos lead to non-Gaussian tails in the two particle source. We note that the emission duration of the system can mask this tail. We illustrate the strong differences between the two-particle source shape in the side and outwards directions in the presence of a lifetime effect. We comment on the observability of these lifetime induced tails through source imaging.

Understanding catalyst behavior during in situ heating through simultaneous secondary and transmitted electron imaging

Howe, Jane Y. ; Allard, Jr., Lawrence Frederick ; Demers, Hendrix ; ... - Nanoscale Research Letters (Online)

In situ heating study via a simultaneous secondary electron (SE) and transmitted electron (TE) microscopy is extremely insightful because information from the surface (SE) and bulk (TE) can be readily obtained. The leached Au/Fe ₂O ₃ catalyst has voids on the surface of Fe ₂O ₃. Upon heating to 500 °C, voids shrank and disappeared, while internal Au species diffused to the surface to form new nanoparticles. Heating in vacuum reduced Fe ₂O ₃ to Fe ₃O ₄. Heating at 700 °C caused coalescence and growth of Au particles and formation of faceted Fe ₃O ₄ surfaces. We achieved 1.1more »« less

Femtoscopy in PHENIX: Evidence for a Long Range Structure in the Pion Emission Source in Au+Au Collisions at RHIC

Chung, P. ; Holzmann, W. ; Lacey, R. ; ... - AIP Conference Proceedings

The PHENIX experiment has acquired {approx}1 billion minimum bias Au+Au events at {radical}(s) = 200AGeV during the year 2004. This high statistics data set, coupled with a state-of-the-art analysis technique, allows for the extraction of 3D emission sources for various particle types. These 3D sources lend fresh insight into the nature of a long-range source previously reported by PHENIX. The new results indicate an anisotropic pion emission source in the pair center of mass system (PCMS) having an extended space-time extent in the outward direction. The two-proton emission source from the same data set is essentially isotropic in the PCMS.more »« less

Three-dimensional two-pion emission source at SPS: Extraction of source breakup time and emission duration

Chung, P., E-mail: pchung@mail.chem.sunysb.ed ; Danielewicz, P., E-mail: danielewicz@nscl.msu.ed - Physics of Atomic Nuclei

A model-independent, three-dimensional source function for pion pairs has been extracted from Pb + Pb collisions at {radical}s{sub NN} = 17.3 GeV. The extracted source exhibits long-range non-Gaussian tails in the directions of the pion-pair net transverse momentum and of the beam. Comparison with the Therminatormodel allows for an extraction of the pion source proper breakup time and of emission duration in the collisions.

Intense nanosecond duration source of 10-250 keV x rays suitable for imaging projectile-induced cavitation in human cadaver tissue

Boyer, Craig N. ; Holland, Glenn E. ; Seely, John F. ; ... - Review of Scientific Instruments

The design, fabrication, and performance of a repetitive nanosecond x-ray source having a pumped field-emission x-ray tube are described. A compact Marx generator, 61 cm in length and storing 12 J energy, directly drives the field-emission tube with voltage pulses >380 kV and with <4 ns rise time from an equivalent generator impedance of 52 {omega}. The x-ray dose is 520 {mu}Sv at a distance of 30.5 cm. A numerical simulation model is used in which the x-ray tube's cathode width and anode-cathode gap spacing are permitted to change with time, while electron flow between the cathode and anode ismore »« less
