Strategies for Time-resolved X-ray Diffraction of Phase Transitions with Laser Compression
ORAL
Abstract
As part of a program to document kinetics of phase transitions under laser-driven dynamic compression, we are designing a platform to make multiple x-ray diffraction measurements during a single laser experiment. Our plans include experimental development at Omega-EP and eventual implementation at NIF. We will present our strategy for designing a robust platform that can effectively document a wide variety of phase transformations by utilizing both streaked and multiple-frame imaging detectors.~~Preliminary designs utilize a novel CMOS detector designed by Sandia National Lab.~~Our initial~experiments include scoping studies that will focus on photometrics and shielding requirements in the high EMP environment close to the target.
