The paper reports on a pulse discharge system operated repetitively up to 35 Hz. The pulse discharge circuit contains two linear flashlamps in series, a thyratron and a pulse capacitor which is charged to a voltage up to 20 kV. The pulse has a duration less than 2 microseconds and a peak current of some kiloamperes. In order to keep the stress on the flashlamps small a two-stage simmer-system is used. The 14 kW-simmer-current supply is based on semiconductors and allows maximum currents of 7 A. It is capable to control a constant current in two modes. To ignite the flashlamps the simmer-current supply is able to generate a single voltage pulse. The paper discusses the design of the system and gives results obtained from tests so far.
