Double Flat Crystal Spectrometer in Dispersive Arrangement for Laboratory XAFS Spectroscopy

A new XAFS spectrometer with a double flat crystal monocromator has been developed. The energy resolution of the spectrometer is estimated to be below 10eV at 20keV from the FWHM of Mo Kα1 line (17.479keV). Experiments under various temperature and vacuum conditions are possible with a movable rotating anode and a high vacuum type sample chamber.
