Instrument

The SCS instrument is a branch beam line and located at the undulator source SASE3 which produces intense X-ray pulses at soft X-ray energies (250 eV - 3000 eV). The SCS beamline can be operated in pink and monochromatic beam mode. The mirror benders of the Kirkpatrick-Baez refocusing optics will deliver the beam to two interaction points separated by 2 meters. This allows not only a small beam focus of 1-2 micrometers for high peak intensities in coherent diffraction imaging experiments but also a variable beam diameter of up to 500 microns. The larger beam diameter optimizes for time-resolved spectroscopy studies by making the best use of the high-average photon flux while avoiding sample damage without further beam attenuation.

The SCS instrumentation encompasses the FFT chamber (forward-scattering and transmission geometries) and the XRD chamber (back- scattering and reflection geometries) for solid samples, as well as the chemistry chamber for liquid jets. The SCS instrument is equipped with 2D array detectors, the 1MPix DSSC detector (4.5 MHz rep rate) and the 2Mpix PI-MTE3 and Marana-X detectors (10Hz), for coherent x-ray diffraction experiments. A high-resolution Resonant Inelastic X-ray Scattering (RIXS) spectrometer, contributed by the Heisenberg-RIXS user consortium, complements the spectroscopy tools at this instrument.
