Static Compression of Gold and Copper and Calibration of the Ruby Pressure Scale to Pressures to 1.8 Megabars (Static.RNO)
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.
