Welcome to the Spectroscopy Group Web Page.


Research at our beamlines focuses primarily on the spectroscopic (XAFS, XRS, Time-resolved, catalysis) and microbeam (microprobe mapping, micro-XAFS, micro-diffraction) applications of hard X-rays.


On this website you should find most if not all of the information relevant to accessing and using the Sprectroscopy beamlines.  If you feel something is missing or needs to be clarified, please contact us.


Regards from the Spectroscopy Group Staff.
