Design of Vacuum Components for a EEHG-Based Short-Pulse Facility at DELTA — •Fin Hendrik Bahnsen, Max Bolsinger, Svenja Hilbrich, Marc Andre Jebramcik, Shaukat Khan, Nils Lockmann, Carsten Mai, Arne Meyer auf der Heide, Robert Molo, Gholamreza Shayeganrad, Peter Ungelenk, and Dennis Zimmermann — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

Since 2011, a short-pulse facility is in operation at the 1.5-GeV synchrotron light source DELTA. Coherent VUV radiation pulses with femtosecond duration are routinely generated using the coherent harmonic generation (CHG) technique which is based on the interaction of electrons with ultrashort laser pulses. In order to generate even shorter wavelengths, an upgrade employing the echo-enabled harmonic generation (EEHG) and femtoslicing schemes is planned for 2017. A new vacuum system for the modified section of the storage ring considering the boundary conditions given by the changed magnetic layout and the existing vacuum setup was designed. The results including simulations of the vacuum profile along the storage ring and wake fields in new chamber parts will be presented.
