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 60-80%; it is an undulator beam line with fully adjustable focus from 100 to 15 microns. 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 EIGER 16M PAD. For aditional information about the experimental capabilities, see http://smb.slac.stanford.edu/index.shtml.

| Data Acquisition and Analysis | The beam line control GUI Blu-ice is installed at all the macromolecular crystallography beam lines. Web-ice provides an interface for diffraction image viewing and automated autoindex and data collection strategy calculation. Other supported software installed on servers accessible from all the beam lines include mosflm, HKL2000 and XDS. MAD/SAD scripts, developed at SSRL, are also available to facilitate on-line structure solution. The graphics package COOT is installed on the local beamline computers. |
