High Pressure Collaborative Access Team located at Sector 16 of Advanced Photon Source is an experimental facility for comprehensive characterization of materials behavior under extreme pressure-temperature conditions by multiple techniques based on synchrotron X-ray radiation. Overview of tools for pressure-temperature generation and to characterize microstructural changes during deformation, phase transitions and other pressure/stress induced processes will be presented, along with some recent case studies. The presentation will be focused on Laue diffraction technique recently developed at HPCAT for real time in-situ microstructural studies under high pressure or uni-axial deformation. Due to fast data collection Laue diffraction is a powerful tool for real time microstructural studies providing multiple orders of magnitude better time resolution, comparing to the most widely implemented monochromatic beam diffraction technique.
