Progress towards short bunches and short pulses at the DELTA storage ring — •Benedikt Büsing, Shaukat Khan, Daniel Krieg, Carsten Mai, and Arne Meyer auf der Heide — Center for Synchrotron Radiation (DELTA), TU Dortmund University, Dortmund, Germany

DELTA is a 1.5-GeV synchrotron light source operated by the TU Dortmund University providing synchrotron radiation in a spectrum from hard X-rays to the VUV regime. The bunch length in a storage ring can be compressed by either increasing the cavity voltage or decreasing the momentum compaction factor. On the other hand, short pulses can be generated by using seeding schemes to modulate a short slice of the bunch by a laser-electron interaction. Latest results on bunch shortening due to a newly installed cavity as well as low-alpha optics and the status of the upgrade plan for the short-pulse source from coherent harmonic generation (CHG) to echo-enabled harmonic generation (EEHG) will be presented.
