This photo shows the first multi-anvil, high-pressure apparatus in the U. S., installed in the High Presssure Laboratory at Stony Brook University in December 1985. It is a 2000-ton, uniaxial split-sphere apparatus [USSA-2000] capable of generating pressures up to 30 GPa and temperatures up to 3000K for sample volumes of 1-5 cubic millimeters. It has been used for petrological, geochemical and geophysical studies of samples recovered from the high pressures and temperatures of synthesis. Further details can be found in: Remsberg, A. R., J.
