(a) Required slit size of the monochromator for the full transmission of a constant bandwidth of Δhν = 2.0% (solid line) and Δhν = 0.5% (dashed line) in first (green) and second (red) diffraction order. (b) Resolving power hν/Δhν at a constant slit size of 1 mm (solid line) and 0.25 mm (dashed line) in first (green) and second (red) order. The bandwidth in the first order (blue) increases up to 8% at hν = 600 eV. In the second diffraction order (magenta) a slightly smaller bandwidth is obtained. As described in the text, in this set-up the resolving power is very low compared with typical monochromator systems. |
