| Research Abstract |
The third generation synchrotron light source has enabled use of brilliant undulator radiation in the hard x-ray region. The aim of the project is to realize x-ray fluorescence spectroscopy using hard x-rays of near ionization threshold of the element of interest.
To realize high resolution x-ray fluorescence spectroscopy we have developed a spectrometer which is composed of a single flat crystal and a position sensitive proportional counter (PSPC). X-rays from a point source are dispersed by the crystal and the dispersed whole spectrum is detected by the PSPC.The energy resolution of the spectrometer can be improved by using an additional scanning slit in front of the detector.
By using the x-ray fluorescence spectrometer and the undulator radiation from the SPring-8 resonant x-ray Raman spectra were measured from the Ni foil, and the threshold x-ray fluorescence spectroscopy of the many systems arein progress.
