Beamline 12.2.2 at the Advanced Light Source is a Synchrotron-based Hard X-ray Diffraction beamline specifically aimed at samples under high pressure within diamond anvil cells. The beamline photon energy range is 6-35keV with an x-ray spot size down to 10x10um. Resistive and laser heating of samples is available up to 3000K.
