Figure 5
Total transmission as calculated by REFLEC (Schäfers, 2008BB32). Shown is the total transmission of the grating beam path as calculated from actual parameters for the diffraction orders m = 1 (solid black line) and m = 2 (red line) for γG1 = 0.50° and γG2 = 0.55°. The dashed line shows the reference transmission for a perfect match of both blazing angles at γ = 0.50°. The order m = 2 extends into the spectral range of the afterburner (Tischer et al., 2022BB39). Additionally, the total unfiltered transmission of the variable-delay beam path (green, right vertical scale) is shown. The red hatched area denotes the energy range which will be achieved by the FLASH2020+ upgrade in the near future.
