BL12-2 is a state-of-the-art microfocus undulator beam line with fully adjustable focus from 15 to 100 microns. Bright micron-sized beams can be achieved by the use of microcollimators. It is optimized for microdiffraction, monochromatic, high-throughput and high-resolution macromolecular crystallography. It is SAD and MAD capable and can be run in a full remote access mode. It is equipped with an Dectris PILATUS 6M detector. Beam line 12-2 was build through funding from the Gordon and Betty Moore Foundation via the California Institute of Technology. 60% of beamtime is available to general users.
