Dear All,

The Berkeley Center for Structural Biology (BCSB) has recently completed
a major upgrade of the Sector 5.0 beamline optics. A five- to tenfold
improvement in available flux has been achieved  at the side-station beamlines
(5.0.1 and 5.0.3), which now generate 1.5x10^11 photons per second at 0.97
Angstrom. This wavelength is slightly above the Se K edge making them ideal for
performing Se SAD experiments.

The performance of 5.0.2 (a tunable beamline) has improved by a factor of
3 to 4. It now generates a peak flux of 8x10^11 photons per second
under typical
user operations. The upgrade has also extended the energy range of
5.0.2 to 16 keV, enabling the routine use of shorter wavelengths and
anomalously scattering elements
such as bromine.

All the BCSB beamlines have robotic sample changers. The sector 5 beamlines are
equiped  with Berkeley Automounters (BAMs). The tuneable beamlines 8.2.1 and
8.2.2 are now equiped with Actor sample changers. Please visit
for more details about the Center and its beamlines.

If you'd like to take advantage of the upgrades to these BCSB beamlines,
submit a General User proposal by May 15, 2008 in order to be
considered for the July-August schedules at the Advanced Light Source.

If you have any questions or would like to request open beamtime,
please e-mailing BCSBBeamtime at lbl.gov.

(Please note that executed user agreements must be received by LBNL
prior to beamtime.  Proprietary fees, if applicable, must be received
by LBNL at least five working days prior to scheduled beamtime.)
