Focused X-ray Thomson Scattering Experiments using the Hybrid X-pinch Radiation Source

X-ray Thomson scattering (XRTS) experiments require intense sources of radiation to probe the high densities present in warm dense matter experiments. Past experiments have utilized free-electron lasers or kilojoules of laser energy coupled to foils to produce these sources. The brightness of X-pinch X-ray sources is shown to be comparable to the X-ray sources used in these previous experiments and suitable for application as an XRTS source with the Ti hybrid x-pinch providing $10^{15}-10^{16}$ photons into 4$\pi$ steradian. We present results of the first XRTS experiments utilizing the hybrid x-pinch as a probe source incorporated in a novel focusing scheme. We use a primary Bragg optic (Ge400) to collect and focus radiation onto a target and a secondary high-efficiency HAPG/HOPG optic to collect the scattered radiation. Results of scattering from heated targets driven by an independent pulser circuit are compared with cold scattering in the non-collective scattering regime.
