Simulated instrumental lineshapes of ten inelastically scattered X-ray beams of the AGM–AGS beamline and spectrometer corresponding to energy losses from 0.2 to 2 eV with energy step 0.2 eV. The energy of incident photons was set to 850 eV. The opening of the entrance slit was set to 10 µm, that of the sample aperture was (a) 2, (b) 20 and (c) 100 µm. The optimal resolution was set at energy loss 1 eV; the slope error of the active gratings was 0.25 µrad r.m.s. Other optical parameters are described in the text. |
