Simulations of spatial normalized intensity distribution of the long (left) and short (right) photon pulse at the source point (top), and at the horizontal focal plane 15 m downstream (bottom). The grazing incidence angle is 1°, the curvature radius is 13 cm, the reflectivity of the selected Rh coating is 80%. The short pulse is emitted 480 µm from the long pulse, in the horizontal plane. The sagittal focusing mirror is placed 7.5 m downstream of the source, and has a sagittal slope error of 1 µrad r.m.s. Colour code is normalized to peak intensity: on a single pulse basis, the short pulse (right) is about three orders of magnitude less intense than the long one.
