THE PRESSURE CALIBRATION UP TO MBARS AND THE ACHIEVEMENT OF 5.5 MBARS UNDER HYDROSTATIC AND NONHYDROSTATIC CONDITION

Abstract
Pressure calibrated up to 0.8 Mbar under hydrostatic condition and to 2 Mbars under non-hydrostatic condition. We find the red shift of ruby R fluorescence to 830nm at the highest pressure point in our diamond high pressure cell. The shift correspond to 5.5 Mbars by calibration.
