Title: Developing a high-flux, high-energy continuum backlighter for extended x-ray absorption fine structure measurements at the National Ignition Facility

Abstract

Extended X-ray absorption fine structure (EXAFS) spectroscopy is a powerful tool for in situ characterization of matter in the high energy density regime. An EXAFS platform is currently being developed on the National Ignition Facility. Development of a suitable X-ray backlighter involves minimizing the temporal duration and source size while maximizing spectral smoothness and brightness. One approach involves imploding a spherical shell, which generates a high-flux X-ray flash at stagnation. Furthermore we present results from a series of experiments comparing the X-ray source properties produced by imploded empty and Ar-filled capsules.

FIG. 1 FIG. 1: The experimental setup. 128 beams drive an implosion in a 1.6 mm diameter GDP shell using the pulse profile shown in the inset (integrated power shown, each beam nominally identical). As shown, one experiment used an empty shell, one shell was filled with 1 atm Ar, and onemore » shell was filled with 4 atm Ar. Time integrated Xray spectra from the implosion are recorded with MACSs on ports 000-000 (polar DIM) and 090-078; a flat {111}- cut Ge crystal is used on 000-000, and a flat {100}-cut quartz crystal is used on 090-078. The X-ray emission at stagnation is imaged using the GXD diagnostic on port 090-315. Dispersed X-rays are recorded with BAS-TR image plates. Temporal X-ray emission is recorded using two DANTE diagnostics on ports 064-350 and 143-274.« less
