Beamline 23-BM-B: Sector 23 - Bending Magnet Beamline

GM/CA-CAT
Life Sciences

Description

This beamline supports macromolecular crystallography, MAD/SAD phasing, and high-throughput sample screening. An ALS-style sample automounter accommodates ALS-Hampton pins in ALS, Unipuck, or Rigagu pucks. The beamline is equipped with an on-axis-microscope allowing parallax free alignment.

Supported Techniques

Macromolecular crystallography

Beamline Controls and Data Acquisition

The GM/CA JBluIce-EPICS user friendly interface retains the look of the original SSRL BluIce, but has been completely rewritten in JAVA at GM/CA to run on EPICS, VME EPICS/MEDM low level interface, PMAC Turbo motion control, and Linux workstations for data collection and processing (Stepanov, et.al. Acta. Cryst. D. 67, 176-188). The JBluIce-EPICS software is an open source available for downloading from GM/CA-CAT files depository.

Detectors

MAR 225 CCD
Ketek SDD for fluorescence spectroscopy

Additional Equipment

Sample automounter BAM-2
On-axis-visualizer
