Sub-nanosecond Time-resolved X-ray Measurements of Multi-material Hybrid X-pinches

POSTER

Abstract

The Hybrid X-Pinch (HXP) has been shown to be an excellent point source of X-ray emission on the XP pulsed-power machine for radiography, producing X-ray radiation with photon energies up to 4keV 1. Spectroscopic analysis of x-pinch dynamics has shown L-shell line emission during the compression phase, followed by a ~10ps continuum burst, with many emission lines in the expansion phase2. Current studies are exploring the use of multi-material wire HXPs utilizing a sub-nanosecond time-resolved radiation technique3. Its goal is to determine if the multi-material wire HXP load configuration can predicably produce temporally spaced x-ray sources within the desired soft X-ray energy bands through material selection. This study is utilizing the 450 kA peak current XP pulsed power generator with a rise time of 60 ns (10 to 90%).
