Title: X-Ray Thomson Scattering from Shock-Compressed Diamond Spheres on the OMEGA Laser

Abstract

X-ray Thomson scattering (XRTS) is an experimental technique that can directly probe the complicated physics of warm and hot dense matter. The Compton-shifted profile of inelastically-scattered x-rays reflects the electron velocity distribution and can measure temperature and density. The ratio of elastically versus inelastically scattered x-rays is related to the number of tightly bound versus free electrons, and thus reflects the ionization state of the sample. Recent experiments highlight uncertainties in the ionization models often used to describe warm dense matter. More experimental validation of these models is needed to understand the onset of ionization in dense plasmas.
