Synthetic phase-contrast imagining using CRASH simulation results

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.
