Commissioning of a new short-pulse facility at the DELTA storage ring* — •Andreas Schick, Mohammed Bakr, Markus Höner, Holger Huck, Shaukat Khan, Robert Molo, Andre Nowaczyk, Peter Ungelenk, and Maryam Zeinalzadeh — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44221 Dortmund, Germany

Since summer 2011, a new source for ultrashort pulses in the VUV and THz regime is under commissioning at the synchrotron light source DELTA. Employing the Coherent Harmonic Generation principle, an ultrashort laser pulse in the near-infrared regime is used to imprint an energy modulation on the electrons in the first part of an optical klystron. After passing a magnetic chicane, the energy modulation is converted into a density modulation, leading to coherent radiation at harmonics of the incident laser wavelength in the second part of the optical klystron. First experimental results have been obtained shortly after the hardware installation was finished. Current work aims at reaching smaller radiation wavelengths by seeding at harmonics of the ultrashort laser and raising the photon flux by optimizing the laser-electron interaction.
