Characterizing Measurements at the U55-Beamline at DELTA — •Ulf Berges1,2, Christoph Keutner1,2, and Carsten Westphal1,2 — 1DELTA/ZfSy, TU Dortmund, Maria-Goeppert-Mayer Str. 2, 44221 Dortmund — 2Experimentelle Physik Ib, TU Dortmund, Otto-Hahn-Str.4, 44221 Dortmund
A VUV-Beamline for linearly polarized synchrotron radiation within the energy range between 55 eV and 1500 eV is operated at DELTA, a synchrotron radiation facility at the University of Dortmund, Germany. The beamline is mostly used to perform XPS- and XPD-experiments with an energy resolution of about E/Δ E = 3000 and a photon flux of about 1e13 photons/s/100mA in the routine mode. New measurements characterizing the present status concerning energy resolution and photon flux of this beamline will be presented. The improved instrumentation of the beamline will be discussed, too.
