Upgrade of the short-pulse facility at DELTA: employing the EEHG and femtoslicing techniques — •Fin Hendrik Bahnsen, Max Bolsinger, Svenja Hilbrich, Markus Höner, Holger Huck, Maryam Huck, Shaukat Khan, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Helge Rast, Gholamreza Shayeganrad, and Peter Ungelenk — 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, a short-pulse facility employing a laser-induced modulation of the electron energy provides sub-picosecond synchrotron radiation pulses in the VUV regime using coherent harmonic generation (CHG). Significantly shorter wavelengths can be reached using the echo-enabled harmonic generation (EEHG) technique. Femtoslicing, another method employing laser-induced energy modulation, allows to reach even shorter wavelengths but with much lower photon flux. At DELTA, an upgrade of the short-pulse facility including EEHG and femtoslicing is planned for the next years. The design of new undulators and magnetic chicanes as well as simulations of the EEHG and femtoslicing process will be presented.
