ExperimentsSAD
Experiments DetailsThe beamline is optimized to address challenging cases in macromolecular crystallography such as large complex molecular assemblies, poorly diffracting crystals and microcrystals by providing extremely stable and intense x-ray beams with beam sizes ranging from 5 to 70 microns.
Special CapabilitiesMicrodiffraction
Special Capabilities DetailsSe-SAD data collection - Microbeams of size 5, 20, 50 and 100 microns are achived by use of beam shaping apertures.

Lab FacilitiesEssential wet lab facility exists. Cold room is available.
Software: NameBeam line is controlled by in house developed "Console" suite of programs. Automated data processing is enabled by locally developed software suite called RAPD. Most of the current crystallographic programs are made available via SBGrid distribution.
Software: Classification
HardwareData storage composed of three NeXan SataBeasts. SAN is accessed via high performance GPFS file system which gives upto 5 times the performance over NFS.
Backup ServicesExternal firewire and USB disks.
