Studies and results for the EEHG upgrade of the DELTA short-pulse source — •Maximilian Schmutzler, Benedikt Büsing, Shaukat Khan, Daniel Krieg, Nils Lockmann, Carsten Mai, Arne Meyer auf der Heide, Bernard Riemann, Boris Sawadski, Frederik Teutenberg, and Peter Ungelenk — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

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 to echo-enabled harmonic generation (EEHG) will enable radiation at shorter wavelengths. The EEHG scheme uses a twofold energy modulation induced by laser-electron interaction and two chicanes to create micro-bunches at the center of an electron bunch. The current status including optics studies, chicane designs and measurements to verify a twofold energy modulation of the same electrons will be presented.

This project is supported by the accelerator initiative (ARD) of the Helmholtz society and by the BMBF under contract 05K16PEB and 05K16PEA.
