Status of the EEHG Upgrade Project of the Short-Pulse Source at DELTA — •Benedikt Büsing, Arne Held, Hubertus Kaiser, Shaukat Khan, Carsten Mai, Arjun Radha Krishnan, and Vivek Vijayan — Center for Synchrotron Radiation (DELTA),TU Dortmund University, Dortmund, Germany

At the 1.5-GeV electron storage ring DELTA, operated by the TU Dortmund University, a short-pulse source based on the coherent harmonic generation (CHG) scheme provides ultrashort pulses in the vaccum ultraviolet regime. In this scheme a laser-electron interaction leads to microbunching within a short slice of an electron bunch which results in coherent emission of radiation. The emitted wavelength is limited to low harmonics of the laser wavelength, higher harmonics are accessible by the echo-enabled harmonic generation (EEHG) scheme, where another laser-electron interaction is added. To implement this scheme, it is necessary to modify the short-pulse source and thus about a quarter of the storage ring. The status of the upgrade project is presented.
