Beamline 12.2.2 at the Advanced Light Source, Sector 12 is an X-ray diffraction beamline for samples at non-ambient conditions of pressure, temperature and atmospheric conditions.
Beamline 12.2.2 at the Advanced Light Source, Sector 12 is an X-ray diffraction beamline for samples at non-ambient conditions of pressure, temperature and atmospheric conditions.
The beamline offers three main areas of expertise:
The beamline offers three main areas of expertise:
- High-pressure X-ray powder diffraction through diamond anvil cells in axial or radial diffraction. Both geometries can be combined with double-sided laser heating and resistive heating.
- Ambient pressure X-ray powder diffraction at temperatures up to ~ 1100 C and simultaneous controlled atmosphere.
- High-pressure X-ray single crystal diffraction allowing for large DAC's (BX90, symmetric cells). This capability is currently available in a single axis configuration on End-Station2. A 4-circle goniometer is commissioned on End-station 1 and open to user operations.
