Shock-compression (Hugoniot) data are considered to give one of most reliable information on the equation of state (EOS) of solids due to the absolute measurement of EOS parameters. Pressure calibration in static compression experiments has been usually undertaken by using the EOS of pressure-scale materials such as Au, Pt, Ag, Cu, MgO, etc. which have been derived from the Hugoniot data. Grüneisen parameter is indispensable physical constant for the study of EOS of condensed matter, but has never or little been experimentally given at high pressure. Grüneisen parameter at high pressure can be obtained from the Hugoniot data of both room and high temperature starting materials. We have established a high-speed streak camera Hugoniot-measurement system consisting of a rotating-mirror type streak camera and long pulsed dye laser combined with a powder gun and two-stage light gas gun to accurately measure the shock velocity and particle velocity. In order to determine the Grüneisen parameter, we developed the Hugoniot-measurement system of high-temperature sample using a high-frequency heating equipment. We have measured the room-temperature Hugoniot data for Au, Pt, W, Ag, Cu, MgO up to >2 Mbars. We succeeded in the measurement of the high-temperature Hugoniot data at temperatures of 400-800℃ on Au, Pt, etc. At the conference, the detailed results of measurement of the Grüneisen parameter at high pressure on Au will be shown.
