Static compression is a useful tool to investigate the materials properties and phase behavior both under uniaxial stress and hydrostatic pressure. From evaluation of the equation of state（P-V-T relationship）to a discovery of near-room temperature superconductivity, the use of diamond anvil cells（DAC）and large-volume presses（LVP）as devices for static compression experiments that couple with synchrotron-based X-ray diffraction, spectroscopy, and imaging techniques achieved pioneering, paradigm-defining scientific advancements in multidisciplinary fields for the past two decades. High-Pressure Collaborative Access Team（HPCAT）is a sector at the Advanced Photon Source dedicated to developing multiple synchrotron-based X-ray techniques to maximize the utility of DAC and portable-LVP techniques to advance compression science. The beamlines are optimized to adapt various sample environments under extreme P-T conditions. HPCAT is comprised of two insertion device beamlines, one for diffraction and the other for spectroscopy, and two bending magnet beamlines, one for general purpose and the other for white-beam application, respectively. Each beamline’s specification and applications are introduced.
