A new tunable beamline for macromolecular crystallography has been in operation since the start of 2003. The X-ray wavelength can be rapidly and reproducibly changed between 6.5 and 17.5 keV (1.9 Å 0.71≈) making the beamline well suited for MAD crystallography. The detector is a MAR CCD mounted on a MAR dtb single-axis goniostat. The beamline is also equipped with a CryoJet cryocooling system, hardware and software for measuring X-ray fluorescence spectra and several fast Linux based computing systems. A wet lab will be constructed this year near the beamline.

The beamline is located at the Center for Advanced Microstructures and Devices (CAMD) in Baton Rouge LA. CAMD is a division of Louisiana State University. The beamline is funded by the NSF and the NIH through the Gulf Coast Protein Crystallography Consortium (GCPCC) which is a group of 13 labs at 8 institutions in Texas, Louisiana and Oklahoma. Members of the GPCC receive 75% of the beam time and the remaining 25% is available to outside users. Researchers wishing to use the beamline or to learn more about it should e-mail gcpcc_access@xray.utmb.edu or contact one of the poster authors.
