X-ray Thomson Scattering Development for Z

ORAL

Abstract

X-ray Thomson Scattering experiments were recently conducted on Sandia's Z machine using a newly developed experimental platform. This platform exploits Z's unique capability to generate large volumes of uniformly shocked warm dense matter. The scattering target is CH$_{2}$ foam (0.1 g/cc), and is designed to reach a temperature (pressure) of 2.4 eV (0.3 Mbar). X-rays generated from a laser heated Mn foil probe the foam in the non-collective regime. An imaging spectrometer collects the scattered x-rays with a spherically-bent Germanium crystal that provides spatial resolution across the shocked and unshocked foam. We present the results and analysis from several fully integrated Z experiments. The resulting spectra are compared to various bound-free scattering models.
