Characterization of the radiation from the CHG facility at DELTA and its application — •Maryam Zeinalzadeh, Mohammed Bakr, Markus Höner, Holger Huck, Shaukat Khan, Robert Molo, Andre Nowaczyk, Andreas Schick, and Peter Ungelenk — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44221 Dortmund, Germany

Several properties of Coherent Harmonic Generation (CHG) radiation like short pulse duration in the femtosecond range, short wavelengths down to the VUV range, and narrower spectrum compared to conventional undulator radiation, make CHG pulses a well-suited tool for time-resolved spectroscopy. The CHG pulses generated by the new short-pulse facility at the DELTA storage ring are characterized under variation of the parameters of the seed laser and the electron bunches. The prospects of employing these pulses in photoemission pump-probe experiments at an existing user beamline are evaluated.
