OPTICAL SYNCHRONIZATION AND ELECTRON BUNCH DIAGNOSTIC AT ELBE

The commissioning of the extended linear electron accelerator ELBE at Helmholtz-Zentrum DresdenRossendorf started in autumn 2012. The new beamlines will deliver short electron pulses with 150 fs duration and bunch charge up to 1 nC. This will drive two THzsources, one broadband CTR/CDR and a narrowband undulator source. To enable highly resolved pump-probe experiments with table top laser sources pump and probe beams have to be synchronized on a 100 fs time scale. This paper describes how the synchronization at ELBE is done for the upcoming experiments and focus on first measurement results of the ELBE bunch arrival time monitor (BAM) based on that system.
