A Johann-type X-ray emission spectrometer at the Rossendorf beamline

Kvashnina, K. O.; Scheinost, A. C.

This paper gives a detailed description of the Johann-type X-ray emission spectrometer recently installed and tested at the Rossendorf Beamline (ROBL) of the European Synchrotron Radiation Facility (ESRF). The spectrometer consists of a single spherically bent crystal analyzer and avalanche photodiode detector positioned on the vertical Rowland cycle of 1m diameter. The hard X-ray emission spectrometer (~ 5 – 25 keV) operates at atmospheric pressure and covers the Bragg angles of 65°–89°. The instrument has been tested at high and intermediate incident energies, i.e. at the Zr K-edge and at the Au L3-edge, in the second experimental hutch of ROBL. The spectrometer is constructed for studying nuclear materials and environmental applications by high energy resolution X-ray absorption and X-ray emission spectroscopies.
