XAFS Measurement System for Nano, Bio and Catalytic Materials in Soft X-ray Energy Region.

In soft X-ray energy region, there are really many absorption edges for the constituents of the useful materials. We have reported the powerful XAFS measurement system at soft X-ray energy beamline on small or compact storage ring HiSOR and also recent NEXAFS spectra data about nano, bio and catalytic materials. The XAFS measurement system has a Be window, which can separate the ultra-high vacuum (UHV) and the atmospheric pressure condition. Moreover the XAFS spectra can obtain by yielding a fluorescent X-ray emitted from the samples. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR]
