Simulated focal spots at a photon energy of hν = 250 eV at the sample position with ideal mirrors. (a) In the grating beam path the simulated spot size amounts to 28 µm (FWHM) in the horizontal and 13 µm in the vertical direction. (b) For the variable-delay beam path the focal spot size amounts to 12 µm (FWHM) horizontal and 13 µm (FWHM) vertical. The broader horizontal focus for the grating beam path indicates a residual pulse front tilt from the monochromator set-up.
