[U-04] Capture the fast process in Earth and planetary science
Materials at high pressures and temperatures are of great current interest for warm dense matter (WDM) physics, planetary sciences, and inertial fusion energy research. At the high-energy density (HED) conditions, the micro-structures of material significantly influence the behavior and properties. Ultra-short X-ray pulse, i.e., X-ray free electron laser (XFEL), is a unique and powerful tool to directly observe a structure and to reveal the time scale of the structural change under the dynamic high pressures. Here we present recent experimental results on shock-compressed planetary materials using high-power laser and XFEL.
