X-Ray Diffraction of Shocked Platinum

ORAL

Abstract

Platinum is often used as a pressure calibrant in diamond-anvil cell experiments, where it is routinely compressed to high pressure–temperature states. Previous experiments have observed the face-centered cubic (fcc) phase of platinum up to 383 GPa.[1]  Laser-driven experiments at the University of Rochester’s Laboratory for Laser Energetics used the powder x-ray diffraction platform [2] on OMEGA EP to extend these measurements for shock and shock-ramped platinum up to 500 GPa. The fcc phase remained stable upon compression until liquid diffraction was observed. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number DE-NA0003856.
