Calculations in a wide VUV through hard-X-ray energy range show that the optimal angle goes with energy progressively more grazing from a few tens of degrees at 50 eV to about one degree at 3.5 keV accompanied by the intensity gain increasing up to a few tens of times as long as the X-ray footprint on the sample stays within the analyzer field of view.
