The new undulator-based beam line X29 has just been declared operational.
It is dedicated to PX (macromolecular crystallography), operates with an
ADSC Q315 detector / diffractometer system, and is in the same brightness
range as X25.  This experimental station was constructed with support from
DOE (BER and BES) and NIH (NCRR), and was a collaboration between the
Center for Synchrotron Biosciences of Albert Einstein College of Medicine
http://www.aecom.yu.edu/home/csb/, and the Macromolecular Crystallography
Research Resource of the Brookhaven Biology Dept.
http://www.px.nsls.bnl.gov/

There is Rapid-Access time available for PX beginning >RIGHT NOW< on NSLS
beamlines.  Also, the deadline for applications for the NSLS's Winter 2005
cycle is the end of the NSLS working day (5PM EDT) on Thursday 30
September 2004.

There is an electronic submission form required.  Please access the web
site: http://www.px.nsls.bnl.gov/ for information about the beamlines, and
forms and instructions for the submission of beam-time proposals and for
Rapid Access.  The deadline is very firm for regular submission.  Read all
of the instructions carefully and submit early.

Nine beamlines are available for macromolecular crystallographic data
collection through the NSLS General User Program: Beamlines X12-B, X12-C,
X26-C, X8-C, X9-A, X6-A, and X4-A, plus the "insertion-device" beamlines
X25 and X29.  (Note: X29 is referred to as X29A on GU program forms.)
Two ADSC Q315 diffractometer systems have been installed at X25
(http://www.px.nsls.bnl.gov/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 beamlines.

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, application of multi-layer monochromators to provide hotter
beams, and multiple-beam phasing of protein structures.
