Abstract :
The Blumlein switch on the Aurora electron accelerator has been improved over the years. The authors describe recent developments and the latest version of this switch. Excellent results are obtained with a half-size (50 cm diameter) trigger electrode that initiates only a single arc in the oil. Placing the arc in the symmetry plane of the downstream prepulse switch, and using only two of its self-breaking arcs, gives output pulses that are reproducible almost to within measurement error.
