Angle Resolved Photoemission Spectroscopy at VUV-FEL — •Martin Marczynski, Matthias Kallaene, Tim Riedel, Soenke Harm, Kai Rossnagel, and Lutz Kipp — Institut für Experimentelle und Angewandte Physik, Universität Kiel, D-24098, Germany

Free Electron Lasers (FELs) are new kinds of light sources that can generate very brilliant ultrashort and coherent photon pulses. Employing 38 eV FEL radiation delivered by the VUV-FEL beamline PG2 at HASYLAB we performed angle resolved photoemission spectroscopy (ARPES) measurements on layered crystals. Electronic structure and space charge effects were investigated as a function of FEL pulse intensity. ARPES spectra were taken on a single shot basis using a hemispherical analyzer with a multichannel detector capable of detecting energy and angle of the photoelectrons in parallel.
