Abstract
We report a new diagnostic technique that allows us to measure simultaneously time- and space-resolved x-ray spectra of high-powered laser-produced plasmas. The simultaneously time- and space-resolved x-ray spectra were measured using a multiframe, electrically-gated, imaging x-ray spectrometer with 100 ps time resolution, and an x-ray streaked crystal spectrograph with a spatial imaging slit. A 4-frame holographic interferometer was used to measure the electron density profiles of the plasma. All three instruments were run simultaneously and allow for the first direct comparison of electron density spatial profiles determined via interferometry and spatially-resolved emission spectra from the plasma at the same instant in time. The CHROMA laser facility at KMS Fusion has been used to irradiate a variety of microdot targets. These targets include aluminum and magnesium microdots as well as targets consisting of a mixture of bromine and magnesium. Preliminary comparison between density and temperature profiles derived from line-intensity-ratio techniques and determined from holographic interferometry and free-bound continuum measurements are presented.
