PGM-Beamline at the Undulator U55 at DELTA — •Ulf Berges1,2, Sven Döring1,2, and Carsten Westphal1,2 — 1DELTA, University of Dortmund, Maria-Goeppert-Mayer Str. 2, 44221 Dortmund, Germany — 2Fachbereich Physik, University of Dortmund, Otto-Hahn-Str. 4, 44221 Dortmund, Germany
A VUV-beamline for linearly polarized synchrotron radiation from a permanent magnet undulator is operated at DELTA, a synchrotron radiation facility at the university of Dortmund, Germany.
The energy range of this PGM-type beamline is 55 to 1500 eV, the calculated focus spot size 70 mum (h) x 30 mum (v). The measured photon flux is about 10^12 photons/s/100 mA at 400 eV and 200 mum exit slit size and cff-value of 2. The beamline can also be operated in a high resolution mode with an expected energy resolution up to 30000. Various measurements concerning energy resolution, flux and beam stability leading towards a characterization of this beamline will be presented. The instrumentation of the beamline will be discussed, too.
