Shock Compression of Iron Foils Relevant to Earth Core Conditions with Intense Laser

POSTER

Abstract

Shock compression experiments were performed on GEKKO-XII/HIPER laser facility at ILE, Osaka University. Iron foils were irradiated to generate the pressure of Earth core ($\sim $ 350 GPa). We measured shock parameters with optical diagnostics, such as velocity interferometer system for any reflector (VISAR) and spectrally streaked optical pyrometer. We also measured with x-ray diffraction technique for determination of shock compressed crystal structure. Simultaneous measurements of optical diagnostics and x-ray diffraction were done for MgO and diamond crystal foils as well as iron foils.
