There is Rapid-Access time available for PX beginning >RIGHT NOW< on NSLS beam lines. Also, the deadline for applications for the NSLS's Winter 2006 cycle is the end of the NSLS working day (5PM EDT) on Friday 30 September 2005.

There is an electronic submission form required. Please access the web site: http://www.px.nsls.bnl.gov/ for information about the beam lines, and forms and instructions for the submission of Rapid-Access and long term beam-time proposals. Our mail-in program is also described, and there is the possibility to arrange to use more than one beam line at once.

Nine beam lines are available for macromolecular crystallographic data collection through the NSLS General User Program: Beam lines X12-B, X12-C, X26-C, X8-C, X9-A, X6-A, and X4-A, plus the "insertion-device" beam lines X25 and X29. The deadline is very firm for regular submission; Rapid Access or mail-in collection can be requested any time. Read all of the instructions carefully and submit early. Two ADSC Q315 diffractometer systems have been installed at X25 (http://www.px.nsls.bnl.gov/x25/x25_info.html) and X29 (http://www.px.nsls.bnl.gov/x29/x29_info.html) to provide unprecedented data-collection power.

 >>>  This represents a huge amount of beam time, including many days <<<
 >>>  on X25 and X29, two of the most usable beamlines anywhere for PX.  <<<

CCD-Based detection systems, as well as sufficient computing power that all data can be reduced on site (and often structures can be solved on site as well) are available on all of these beam lines.

Support from the office of Biological and Environmental Science of the US Department of Energy, and a Research Resource Grant from the National Institutes of Health, is providing enhanced support for users to the NSLS. Work is being done under this grant to extend the state of the art in macromolecular crystallography in both computing hardware and software, use of modern detectors, and provision of specimen-mounting robots.
