Abstract

We have been developing experiments on shock compression relevant to Earth core condition with intense laser irradiation. Multiple shock compression method is applied to create pressure and temperature (P, T) conditions of geophysical interest. We measured sound velocity of shock-compressed iron foils with two-stepped laser pulse irradiation by x-ray radiography technique. We have also developed nanosecond x-ray diffraction in order to measure the structure of shock-compressed materials.
