X-ray spectra of laser irradiated metal foils for X-ray Thomson scattering of warm dense matter on the Z-Accelerator

摘要

Accurate measurements of warm dense matter (WDM) physical properties, such as temperature, density, and ionization state, are important for understanding and modeling high-energy density physics. X-ray Thomson scattering has been used to probe WDM states generated with high-power lasers. The Z-Accelerator has the capability to create WDM states with greater uniformity, larger size, and longer duration than that achievable on laser-driven experiments. Magnetically launched flyers experiments on the Z-Accelerator utilizing the Z-Backlighter Laser (ZBL) to generate x-rays for scattering of shock-compressed samples are in preparation. Alternatively, experiments are being designed to use x-ray radiation from a z-pinch implosion to isochorically heat and probe samples.
