Optimizing Bandwidth and Flux on an X-ray Streak Camera for Laser-Produced Plasma Spectroscopy*

Laser-produced plasmas emit x-rays that convey their temperatures, densities, and dynamics, but x-ray detectors capable of sub-picosecond time resolution have small detector area size that limits energy bandwidth. We conducted raytracing and analytical simulations to optimize placement of a Bragg crystal in upcoming laser experiments for desired spectral range and maximal intensity. Analytical simulations also predicted the slope from photon time-of-flight and spectral resolution for streak camera data. The geometry was implemented in a LaserNetUS experimental campaign in May 2023 at ALEPH using an x-ray streak camera. Simulation predictions are compared to experimental data collected at ALEPH and an analysis of the relationship between intensity measurements and laser power is performed.
