Abstract

New experimental results on the static compression of gold and copper in the diamond-window, high-pressure cell have provided the basis for an accurate system of pressure calibration at ultrahigh pressures. The unit-cell volumes of gold and copper were measured at several points along the pressure curve by MoKα x-ray diffraction. Diffraction measurement was by film methods. At each point, the luminescent spectrum of ruby also contained in the high-pressure cell was measured. The shift with pressure of the luminescent R-line emission of ruby was calibrated to the shock-wave equation of state of gold and copper to 1.8 Mbar.
