SSRL website

SSRL is a general user facility with a small number of PRT beam lines. General user beam lines are scheduled with 100% access for a broad user community from Universities, National Laboratories and industry. PRT beam lines provide typically 33% of their time to general users and the remaining to the participating research teams. Beam time is awarded on a peer-reviewed basis via proposals submitted to the SSRL User Administration. The Structural Molecular Group (SMB) at SSRL is responsible for the operation of 8 beam lines, of which five are dedicated to macromolecular crystallography, two to x-ray absorption spectroscopy and one to small angle x-ray scattering. Additional time for XAS is provided on shared beam lines.

About Structural Biology at SSRL

CrystallographyAtSSRL.gif Macromolecular Crystallography Group
The Macromolecular Crystallography Group at the Stanford Synchrotron Radiation Laboratory operates and develops X-ray beamlines, providing state-of-the-art macromolecular crystallography facilities and support for visiting and remote researchers. Of the beamlines currently operational, BL12-2, BL9-2 and BL14-1 are designed for MAD experiments; the side stations BL9-1, BL7-1 and BL11-1 are also MAD capable at slightly reduced energy resolution. BL12-2, with an undulator source, is optimized for microbeam applications. All SSRL beamlines can be operated from the user's laboratory or any other remote location.
