Status and latest improvements of the short-pulse facility at the DELTA storage ring* — •Andreas Schick, Markus Höner, Holger Huck, Shaukat Khan, Robert Molo, Peter Ungelenk, and Maryam Zeinalzadeh — Center for Synchrotron Radiation (DELTA), TU Dortmund University, 44227 Dortmund, Germany

The new short-pulse facility at the synchrotron light source DELTA utilizes the interaction of the electrons with an ultrashort laser pulse in an undulator (Coherent Harmonic Generation principle). Subsequent microbunching leads to coherent radiation of sub-ps pulses in the VUV regime, which will be used for time-resolved photoelectron-spectroscopy experiments. In addition, coherent, ultrashort THz pulses are generated. Improvements regarding the stability, availability and reliability are presented. Furthermore, the progress towards the emission of shorter wavelengths and towards pump-probe experiments at an existing user beamline are shown.
