Outline of Final Research Achievements

Matter at high temperatures and pressures has been widely studied, often using X-ray diffraction, which can directly probe the ion structure of systems. Until recently, this diagnostic was not feasible with low-Z liquid materials, due to the weak scattering cross-section. However, with the increased brilliance available at X-ray Free Electron Lasers, we have succeeded in observing light elements in systems without strong structural order using diffraction for the first time. We also consider novel approaches to studying highly non-equilibrium systems at XFELs, using heating with optical lasers and the X-rays themselves, with SACLA's two-color mode.
