Experimental Station 9-2 | Stanford Synchrotron Radiation Lightsource

Beam line 9-2 is a wiggler end station dedicated for monochromatic, high-throughput and high-resolution macromolecular crystallography and optimized for SAD and MAD experiments. It can be run in a full remote access mode. It is equipped with a Dectris Pilatus 6M PAD detector and a remote access controlled UV-Vis microspectrophotometer. 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 beamlines 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.
