  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.
