Seeding experiments using the echo-enabled harmonic generation scheme at DELTA — •Arjun Radha Krishnan1, Benedikt Büsing1, Shaukat Khan1, Carsten Mai1, Wa'el Salah2, and Vivek Vijayan11Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany — 2The Hashemite University, Zarqa, Jordan

Free-electron lasers use the echo-enabled harmonic generation (EEHG) scheme as a seeding method. However, the technique can be employed at storage rings for the generation of ultrashort radiation pulses, as well. At DELTA, a 1.5-GeV synchrotron light source operated by TU Dortmund University, recently an EEHG setup was implemented. Here, two-fold laser-electron interaction in two undulators, each followed by a magnetic chicane, is used to generate a density pattern with high harmonic content, leading to coherent radiation emission at harmonics of the laser wavelength. The implementation at DELTA is the world-wide first of its kind at a storage ring. The experimental setup and the present status of the project are presented.
