High-speed monochromatic x-ray imager for electron temperature mapping of fast igniter plasmas

Abstract

We report on experiments aimed at obtaining laser-imploded core plasma temperature maps using two color, monochromatic x-ray imager. This instrument uses two toroidally bent Bragg crystals and a high-speed sampling imager to provide spatial resolution of 25 μm, temporal resolution of 20 ps, and spectral resolution over 200, simultaneously. Using a deuterated plastic shell target filled with CHClF2 gas, time-resolved monochromatic x-ray images in the Cl-Heβ and Cl-Lyβ were successfully obtained. © 2010 IOP Publishing Ltd.
