Development of Laser-Produced High-Energy X-ray Sources for Phase Contrast Imaging

POSTER

Abstract

Experiments performed on the TRIDENT-200TW facility show phase contrast effects from K-alpha x-ray sources produced from 2-ps laser pulses using 17-keV Mo backlighters. These low magnification images show high-spatial resolution and enhanced contrast on these 3-mm undriven CH disks. We will compare these results to some predictions and discuss plans to measure dynamic properties of shocked material on the OMEGA-EP facility. Results from pulse duration scaling on OMEGA-EP will also be presented.

*Work performed under the auspices of the Dept. of Energy under contract DE-AC52-06NA25396.
