Full-Automatic XAFS Measurement System of the Engineering Science Research II beamline BL14B2 at SPring-8

The Engineering Science Research II beamline BL14B2 at SPring‐8 is a hard X‐ray bending magnet beamline covering the wide energy range from 3.8 to 72 keV, and has been open to XAFS users since September 2007. The gas distribution and exhaust gas treatment systems have been installed for the in‐situ XAFS measurements. Recent improvements in the speed of XAFS measurements have increased the demand for automated measurements. We have developed such a system, in which the adjustment of X‐ray optics and the XAFS measurement in transmission mode can be performed automatically.
