(Group Report) Status of the Short-Pulse Facility at DELTA — •Fabian Götz, Fin Hendrik Bahnsen, Max Bolsinger, Svenja Hilbrich, Markus Höner, Marc André Jebramcik, Shaukat Khan, Nils Lockmann, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Raffael Niemczyk, Gholamreza Shayeganrad, Peter Ungelenk, and Dennis Zimmermann — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

At the 1.5-GeV synchrotron light source DELTA operated by the TU Dortmund University, femtosecond laser pulses interact with electrons in order to generate coherent ultrashort radiation pulses in the VUV regime (coherent harmonic generation, CHG). The electric field of the laser pulses modulates the electron energy. By passing a magnetic chicane, this energy modulation is converted into a density modulation, which gives rise to coherent radiation at harmonics of the laser wavelength. In this contribution, a general overview of the DELTA short-pulse facility and methods to characterize the CHG radiation are presented. To control the shape and the spectra of the CHG pulses, studies using a scanning monochromator with an APD as a detector and a single-shot spectrometer based on a gated CCD camera were carried out. The CHG radiation spectra change under variation of the laser pulse properties and chicance strengths. Finally, spectral measurements are compared with simulations of the microbunching process and the CHG radiation.
