Synthetic phase-contrast imagining using CRASH simulation results
POSTER
Abstract
Recent laboratory experiments explored radiation hydrodynamics of a laser driving a shock into
a water jet target. The experiment used a betatron x-ray source to create a phase contrast
image. This study uses CRASH, a radiation-hydrodynamics code developed at the U. of
Michigan, to simulate the experiment. The simulation results are used to create a synthetic
phase contrast image. This study will show the steps required to create this image, and a
detailed comparison to the experimental result. Finally, we show how valuable this
measurement technique can be by comparing it to other synthetic images CRASH is capable of
creating.
