New developments in large volume static compression with in situ synchrotron x-ray diffraction at High Pressure Collaborative Access Team (HPCAT) at the Advanced Photon Source

The integration of x-ray diffraction measurements with physical properties characterizations in a large volume cell provides a unique opportunity to investigate in-situ correlation between the atomic structure and the macroscopic properties of matter at high pressure (P) and high temperature (T) conditions. The beamline 16-BM-B capable of near comprehensive large-volume sample characterization at high P and high T conditions in a Paris-Edinburgh (PE) cell by using a multitude of in-situ x-ray-based techniques. An overview of the supported techniques that are available to users, with emphasis on new developments, is presented. Available techniques include: double-stage PE for amorphous structural measurements above 100 GPa, ultrasonic echo, tomography, fluid viscosity, high P-T synthesis, x-ray absorption density measurement, powder diffraction, phase contrast radiography, liquid (im)miscibility, and thermoelectric properties measurements.
