Figure 2
Focal spot size (FWHM) of the KB optics simulated in SHADOW. The focus size is 4.1 µm × 6.7 µm (vertical × horizontal). The simulation was carried out for a 13.5 nm FEL photon wavelength, the PG monochromator in first order (cff = 2) and an exit slit width of 20 µm. Surface roughness and slope error of each focusing optical element of the beamline were taken into account.
