High pressure ruby scale
WebAug 15, 2024 · Abstract High-Pressure Collaborative Access Team (HPCAT) is a synchrotron-based facility located at the Advanced Photon Source (APS). With four online experimental stations and various offline capabilities, HPCAT is focused on providing synchrotron x-ray capabilities for high pressure and temperature research and supporting … WebAn accurate pressure determination is central to all high-pressure experiments. The commonly used ruby fluorescence pressure scale has high intrinsic precision (60.5% under hydro-static conditions), but low accuracy (65%) because it is a secondary scale calibrated by primary standards deduced from high-temperature shock-wave data (27, 28).
