    Overview
    SPEAR3

    Micro-focus Macromolecular Crystallography In-vacuum Mini-gap Undulator End Station

    Beam line 12-2 is a PRT station, realized through third party funding from the Gordon and Betty Moore Foundation via the California Institute of Technology and available to general users 70%; it is a 134-pole, 1.0-Tesla in-vacuum undulator beam line with fully adjustable focus from 100 to 15 microns. smaller 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 a Dectris PILATUS 6M detector.

    See the Macromolecular Crystallography website for technical details.
