X23A2: An XAS Beamline at NSLS Operated by The National Institute of Standards and Technology
X23A2 is an X-ray Absorption Spectroscopy XAS beamline focusing mainly on materials science applications of XAS but which is also an excellent beamline for XAS applications in other fields. X23A2 is run by the Synchrotron Methods Group of the Ceramics Division at NIST. Joe Woicik is the spokesperson and scheduler. Bruce Ravel is the local contact. Here is a PDF file explaining our group's work. (13.8 MB)
