Figure 3
A schematic description of the experimental configuration of the SPB/SFX instrument at the European XFEL and (inset) the related pulse timescales. The beamline consists of two pairs of mirrors for photon transport and focusing: (i) a pair of horizontal offset mirrors (M1 and M2) and (ii) a pair of Kirkpatrick–Baez elliptical mirrors that focus the beam independently in the horizontal (NHE) and vertical (NVE) directions (Bean et al., 2016

). The focusing optics are preceded by a pair of beam-conditioning slits set to form a 3.8 mm square aperture in the transverse plane.
