The THz Beamline at DELTA: Commissioning, First Experimental Results, and Future Plans* — •Peter Ungelenk, Mohammed Bakr, Markus Höner, Holger Huck, Shaukat Khan, Robert Molo, Andre Nowaczyk, Andreas Schick, and Maryam Zeinalzadeh — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44221 Dortmund, Germany

DELTA is a 1.5 GeV synchrotron light source operated by the TU Dortmund University. A dedicated THz beamline, which extracts and detects coherent THz pulses caused by a laser-induced density modulation of the electron bunches, has been constructed and commissioned during 2011. Using a liquid-helium-cooled bolometer as detector, first experimental results regarding the bunch profile, the dependence of the THz signal on the bunch current, and the laser-electron overlap at the new short-pulse facility were obtained. Future plans include the improvement of stability and availability as well as the construction of an experimental endstation for FT-IR spectroscopy.
