Higher order momentum compaction in electron storage rings and capabilities for the generation of coherent synchrotron radiation — •Markus Ries1, Jörg Feikes1, Peter Schmid1, Godehard Wüstefeld1, Arne Hoehl2, Roman Klein2, Ralph Müller2, Anton Serdyukov2, and Gerhard Ulm21Helmholtz-Zentrum Berlin, Berlin, Deutschland — 2Physikalisch-Technische Bundesanstalt, Berlin, Deutschland

Various electron storage rings undertake strong efforts to create very short bunches. This serves the generation of coherent synchrotron radiation (CSR) and the use of extremly short pulses in time resolved X-ray spectroscopy. Recently built machines explore the capabilities arising from controlling higher orders of the momentum compaction factor (α=α01δ+α2δ2…) that strongly dominates the longitudinal beam dynamics. The Metrology Light Source (MLS) is the first electron storage ring that uses additional sextupoles and octupoles to control the three leading terms of α. The resulting possibilities and some first experimental results will be given.
