Theoretical (calculated) efficiency spectra for the gratings in the REIXS XES spectrometer, over their intended ranges of operation. Using the LEG, MEG and HEG, we achieved our goal of >10% efficiency from 100 to 1000 eV. The IMP grating provides high efficiency at low resolution over a wide wavelength range, and the two third-order gratings provide a very high resolution mode.
