Current status of the EEHG upgrade plan at the DELTA short-pulse source — •Benedikt Büsing, Shaukat Khan, Daniel Krieg, Carsten Mai, Arne Meyer auf der Heide, Maximilian Schmutzler, and Frederik Teutenberg — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

To generate short pulses at short wavelengths in storage rings, seeding schemes from free-electron lasers can be adopted. Energy modulation induced by laser-electron interaction leads to micro-bunching and coherent emission of radiation.

At DELTA, a 1.5-GeV synchrotron light source operated by the TU Dortmund University, a short-pulse source based on coherent harmonic generation (CHG) is used to generate sub-picosecond synchrotron radiation pulses in the VUV regime. An upgrade torwards echo-enabled harmonic generation (EEHG) is planed to reach even shorter wavelengths. The current status and simulation results including optics studies for the future lattice will be presented.

This project is supported by the accelerator initiative (ARD) of the Helmholtz Association and by the BMBF under contract 05K16PEA.
