The x-ray experimental endstation of beamline BL9 at DELTA — •Michael Paulus, Christian Sternemann, Christina Krywka, Andreas Schacht, and Metin Tolan — Experimentelle Physik I/DELTA, Technische Universität Dortmund, Maria-Goeppert-Mayer Str.2, 44221 Dortmund, Deutschland

The Dortmund Electron Accelerator DELTA is a synchrotron radiation source located at the TU Dortmund, Germany, and is operated a 1.5 GeV with a maximum electron current of 120 mA and lifetimes of about 10 hours. The beamline BL9 is attached to a superconducting asymmetric wiggler which supplies radiation in the energy range between 4 keV and 30 keV. The incident radiation is monochromatized by means of a Si (311) double crystal monochromator with sagittally bend second monochromator crystal. The experimental endstation of BL9 is equipped with a Huber six-circle diffractometer and is dedicated to (grazing incidence) x-ray diffraction and x-ray reflectivity studies on solid surfaces, thin films and liquid - solid interfaces. Recently, the end station was extended to perform small and wide angle x-ray scattering experiments making use of an image plate scanner. Moreover, a spectrometer in Rowland geometry is accessible to perform resonant inelastic x-ray scattering experiments.
