ID-B

Beamline 16ID-B is dedicated for high pressure micro-x-ray diffraction (µ-XRD).  The station holds two experimental tables: general purpose (GP) table and laser heating (LH) table. The two-table configuration allows a wide range of experimental techniques to be incorporated with high stability for structural studies under high pressures and at various temperatures, using the developed diamond anvil cell techniques such as double-sided laser heating, external heating, cryogenic cooling, time-resolved diffraction,  etc.
