Demonstration of space-resolved x-ray Thomson scattering capability for warm dense matter experiments on the Z accelerator

High Energy Density Physics

Ao, Tommy A.; Harding, Eric H.; Bailey, James E.; Lemke, Raymond W.; Desjarlais, Michael P.; Hansen, Stephanie B.; Smith, Ian C.; Geissel, Matthias G.; Maurer, A.; Reneker, Joseph R.; Romero, Dustin H.; Sinars, Daniel S.; Rochau, G.A.; Laros, James H.

Experiments on the Sandia Z pulsed-power accelerator have demonstrated the ability to produce warm dense matter (WDM) states with unprecedented uniformity, duration, and size, which are ideal for investigations of fundamental WDM properties. For the first time, space-resolved x-ray Thomson scattering (XRTS) spectra from shocked carbon foams were recorded on Z. The large (>20 MA) electrical current produced by Z was used to launch Al flyer plates up to 25 km/s. The impact of the flyer plate on a CH2 foam target produced a shocked state with an estimated pressure of 0.75 Mbar, density of 0.52 g/cm3, and temperature of 4.3 eV. Both unshocked and shocked portions of the foam target were probed with 6.2 keV x-rays produced by focusing the Z-Beamlet laser onto a nearby Mn foil. The data are composed of three spatially distinct spectra that were simultaneously captured with a single spectrometer with high spectral (4.8 eV) and spatial (190 μm) resolutions. Detailed spectral information from three target locations is provided simultaneously: the incident x-ray source, the scattered signal from unshocked foam, and the scattered signal from shocked foam.
