Recent Progress Towards the EEHG-Based Short-Pulse Facility at DELTA — •Nils Lockmann, Fin Hendrik Bahnsen, Max Bolsinger, Fabian Götz, Svenja Hilbrich, Marc Jebramcik, Shaukat Khan, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Raffael Niemczyk, Helge Rast, Gholamreza Shayeganrad, Peter Ungelenk, and Dennis Zimmermann — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

In the field of photon science, the demand for brilliant radiation at short wavelengths with shortest pulse durations keeps growing. At the synchrotron radiation source DELTA operated by the TU Dortmund University, this is achieved by an interaction of a short laser pulse with highly relativistic electrons. The currently used coherent harmonic generation (CHG) technique leads to femtosecond synchrotron radiation pulses in the VUV regime. However, the so-called echo-enabled harmonic generation (EEHG) scheme promises to reach much shorter wavelengths. Therefore, the short-pulse facility will be modified in order to implement EEHG as well as the femtoslicing technique, another method providing short pulses with short wavelengths using the laser-electron-interaction.

In this contribution the status of the upgrade will be presented, including the magnetic layout of the storage ring, the laser system and hardware components.
