Overview of High-Pressure Collaborative Access Team (HPCAT) facility at the Advanced Photon Source at Argonne National Laboratory*

High-Pressure Collaborative Access Team (HPCAT) is a dedicated facility for high pressure research and is located within the Advanced Photon Source (APS) at Argonne National Laboratory.

Goal of HPCAT is to develop and implement synchrotron-based x-ray techniques that are coupled with diamond anvil cell (DAC), portable large volume press (LVP), and other platforms for studying materials at extreme pressure-temperature conditions.

Comprised of four simultaneously operational beamlines HPCAT provides broad range of cutting-edge x-ray techniques, as well as complementary high-pressure support equipment.  Over the years numerous high-pressure x-ray diffraction, x-ray spectroscopy, and x-ray imaging techniques have been developed and established for high pressure research through a robust national laboratory and university partnership, and broad general user community.

Currently, HPCAT has 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.  Our presentation will provide overview of HPCAT and some of the available online and offline techniques, as well as some of the recent experimental techniques being developed.  Furthermore, we will also discuss plans for upgrades at HPCAT that will take place as part of the broader upgrade to the Advanced Photon Source (APS-U).
