BM-B

The HPCAT 16BM-B beamline is dedicated to white beam x-ray diffraction and radiography researches of matters under high pressure.

The station has two major setups: a Paris-Edinburgh cell (PEC) for samples requiring a large scattering volume, especially, for the high-temperature melt and amorphous structure, and Micro-focused white beam Laue diffraction optimized for high pressure.
