Abstract: The Materials Imaging and Dynamics (MID) instrument at the European X-rayFree-Electron Laser Facility (EuXFEL) is equipped with a multipurpose diagnosticend-station (DES) at the end of the instrument. The imager unit in DES isa key tool for aligning the beam to a standard trajectory and for adjusting opticalelements such as focusing lenses or the split-and-delay line. Furthermore, theDES features a bent-diamond-crystal spectrometer to disperse the spectrum ofthe direct beam to a line detector. This enables pulse-resolved characterizationof the EuXFEL spectrum to provide X-ray energy calibration, and the spectrometeris particularly useful in commissioning special modes of the accelerator.Together with diamond-based intensity monitors, the imager andspectrometer form the DES unit which also contains a heavy-duty beamstop atthe end of the MID instrument. Here, we describe the setup in detail andprovide exemplary beam diagnostic results.
