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

  With the expansion of the radiation source ELBE a center for high power radiation sources is being built at the Helmholtz Zentrum Dresden-Rossendorf (HZDR). In a first step (January 2012) the available CW RF-power (1.3 GHz) per superconducting 9-cell TESLA cavity at ELBE had been increased from 8.5 kW to 20 kW (CW) using solid state amplifiers. In a second step the performance of several machine components of ELBE must be redesigned to enable full power operation without risks. The poster gives an overview how these problems have been solved at ELBE and reports on the commissioning.
