Illustration of the energy-compensation principle of grating dispersion applied to a RIXS measurement. Both gratings have an identical central groove density and the same distance to the sample. After passing through the entrance slit, X-rays of varied energy are dispersed onto the sample and experience inelastic scattering. Scattered X-rays of identical energy loss ( or ) are dispersed and focused to the same point on the CCD. |
