Optical Synchronization and Electron Bunch Diagnostic at the quasi-cw accelerator ELBE — •Michael Kuntzsch^1,2, Ulf Lehnert¹, Fabian Röser¹, Marie Kristin Czwalinna³, Sebastian Schulz³, Holger Schlarb³, and Silke Vilcins³ — ¹Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany — ²Technische Universität Dresden, Dresden, Germany — ³Deutsches Elektronen-Synchrotron, Hamburg, Germany

The continuous wave electron accelerator ELBE is upgraded to generate short and highly charged electron bunches (~200fs duration, up to 1 nC) with an energy of up to 40 MeV. In the last years a prototype of an optical synchronization system using a mode locked fiber laser has been build up which is now in commissioning phase. The stabilized pulse train can be used for new methods of electron bunch diagnostics like bunch arrival time measurement with the resolution down to a few femtoseconds. At ELBE a bunch arrival time monitor (BAM) has been designed and tested at the accelerator. The contribution will show the concept of the femtosecond synchronization system, the design of the BAM and first measurement results.
