Dear All, The deadline for general user proposals for PX beamtime at the ALS is coming up soon (Jan 15)! At the BCSB, we have 5 beamlines for which you can apply for beamtime. At the Berkeley Center for Structural Biology (BCSB) we have recently completed a number of upgrades: Sector 8: Recent improvements include: * A high-accuracy microdiffractometer on BL 8.2.1, allowing for centering and viewing of very small crystals * Robotic automounters which can increase the screening throughput at the beamlines, and allows for the implementation of remote data collection. * A new large format (315mm active surface area) CCD detector on BL 8.2.1, facilitating data collection on large unit cell crystals Sector 5: Beamlines (5.0.1 and 5.0.3) 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. Beamline 5.0.2 (the tunable beamline) generates a peak flux of 8x10^11 photons per second, and the energy range of 5.0.2 has been extended to 17 keV, enabling the routine use of shorter wavelengths and anomalously scattering elements such as bromine. Remote data collection for general users on sector 5 is currently being tested for a limited number of users. Please contact beamline staff for details. Please visit http://bcsb.lbl.gov/ for more details about the Center and its beamlines. If you'd like to apply for next round of beamtime (March-April) at the Advanced Light Source, please submit a General User proposal by Januari 15, 2009. To find out more, click on: http://www-als.lbl.gov/als/quickguide/independinvest.html We invite you to submit a proposal at: http://alsusweb.lbl.gov/4DCGI/WEB_GetForm/PXProposalEntry.shtml/Initialize If you have any questions or would like to request open beamtime, please e-mail [email protected]. (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.) ----------------------------------------------------------------- P.H.
