Abstract:
The total electron yield (TEY) mode has been developed successfully for XANES measurements at Beamline 4B7A of BSRF (Beijing Synchrotron Radiation Facility). Its performance was studied by measuring sulphur K-edge XANES of three CdS samples (mixed with graphite powder as an electric conductor) with different concentration: 75%, 50% and 25%. The data are collected in TEY mode and fluorescence yield (FY) mode respectively for comparison. The results demonstrate that the TEY spectra of three samples agree well with each other after the background is subtracted and normalized. The measured XANES spectra by TEY mode without bias and with 100V bias are almost identical to one another, but the signal-to-noise ratio of spectra measured without bias is better than that with 100V bias. The consistency of the self-absorption corrected FY spectra and TEY spectra are within 10% for the three samples.
