Paper Abstract

This paper presents the status of free electron laser (FEL) research at the DLR aimed to develop a high power mm-wave source. A commercial Marx generator (max. 1 MV, 10 stages) has been installed, together with a pulse forming line (Blumlein type, 100 nsec pulse duration) and a cold-cathode diode, both being designed at the ITP. The drift tube (2 cm diameter) represents an overmoded waveguide with a conical horn antenna for outcoupling. The helical wiggler (40 periods with 2 cm pitch length) is able to produce up to 1000 Gauss on axis. At the first step of the experiment, the guide field is set to 1400 Gauss. The installation of a stronger guide field is planned for the future.
