From sweet from bnl.gov Fri Oct 23 07:02:39 2009 From: sweet from bnl.gov (Robert Sweet) Date: Fri Oct 23 10:44:35 2009 Subject: [X-plor] Beam time is available at the NSLS Message-ID: Please visit the website at www.px.nsls.bnl.gov and select "Get Access to Beam Time." The PXRR (Macromolecular Crystallography Research Resource at the NSLS) operates five beamlines for macromolecular crystallography (MX). Two of these beamlines are undulators: X29 is the most efficient MX machine east of Chicago in the US, often serving three different research groups in a day. X25 is as bright, and has counted Rod MacKinnon, Tom Steitz, and Venki Ramakrishnan among its prize-winning users. Typical beam sizes at these undulators are 50 microns. If your crystal is only 20 microns, we can give you a beam that size. There are ALS-style automounters at X29 and two of our dipole beamlines, X12-B and X12-C. We have a new station at X26-C for the coordinated measurement of optical absorption spectroscopic and x-ray diffraction data. Several publications have come from this work and many projects are underway. A Raman spectrometer is being installed now. The PXRR is funded jointly by the NIH's National Center for Research Resources and the DOE's Office of Biological and Environmental Research. ========================================================================= Robert M.
