Abstract

A soft x-ray reflectivity beamline is operational on Indus-2 synchrotron source since 2016 for reflectivity, transmission and absorption measurements in 100-1500 eV photon energy range. To perform spectroscopic experiments in 60-1000 eV spectral range a soft x-ray emission spectrometer (SXES) is designed which will serve as an additional experimental station on the beamline. The SXES setup is designed using aberration corrected varied line spacing flat filed gratings which will disperse soft x-ray emission photons on a CCD screen. Gratings of nominal line density of 1200 l/mm and 2400 l/mm are used to cover 60-250 eV and 120-1000 eV energy range respectively.
