Abstract

Copyright © 2014 CC-BY-3.0 and by the respective authors.At the ELBE radiation source two super-radiant THz sources, a broad-band trasnsition/diffraction radiation source and a planar undulator narrow-band source are under commissioning. At present the facility is driven from the ELBE linac with a CW electron beam of 100 kHz repetition rate and up to 100 pC of bunch charge. With the upgraded SRF electron gun bunch charges up to 1 nC will become available. For the beam energies in the 20-30 MeV range buch compression into the sub-200 fs range becomes a major challenge. We present beam dynamics calculation of the attempted bunch compression scheme as well as first measurements obtained during the commissioning.
