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.
