Spatio- and time dependent Propagation Simulations of hard X-ray FEL radiation through the split-and-delay unit for the HED-instrument at the European XFEL — •Victor Kärcher1, Sebastian Roling1, Liubov Samoylova2, Karen Appel2, Frank Siewert3, Ulf Zastrau2, Frank Wahlert1, and Helmut Zacharias11Center for Soft Nanoscience, Münster, Germany — 2European XFEL, Schenefeld, Germany — 3Helmholtz-Zentrum für Materialien und Energie, Berlin, Germany

For the High Energy Density (HED) instrument at the SASE2 - Undulator at European XFEL an x-ray split-and-delay unit (SDU) is built covering photon energies from hν = 5 KeV up to hν = 24 KeV. This SDU will enable time-resolved x-ray pump / x-ray probe experiments as well as sequential diffractive imaging on a femtosecond to picosecond time scale. In order to reach intensities on the order of 1015 W/cm2 the XFEL pulses will be focused by means of compound refractive lenses (CRL) to a diameter of D = 24 µm. The influence of wavefront disturbances caused by height- and slope-errors of the mirrors inside the SDU on the quality of the two focused partial beams is studied by wavefront propagation simulations using the WPG-framework.
