Figure 2
Calculated total transmission of the mirror coatings used in the different beam paths based on CXRO (Henke et al., 1993), assuming a FEL beam p-polarized in the horizontal plane. The grazing incidence angle ϑv = 1.8° is associated with the variable beam path, and a grazing incidence angle of ϑf = 1.3° is applied in the fixed beam path. Note that only the same type of mirror coating [Ni (red and green) or Pt (blue and magenta)] can be chosen simultaneously. |
