A 5kV, 3MHz Solid-State Modulator Based on the DSRD Switch for an Ultra-fast Beam Kicker
Benwell, A.
A solid-state modulator is being developed at the SLAC National Laboratory for ultra-fast broadband beam deflection. The modulator design is based on an opening switch topology that uses Drift Step Recovery Diodes (DSRDs) as the opening switches. The modulator provides nan-second length pulses into a 50 omega load, i.e. a trip line kicker. The rise and fall time of the kicker is primarily determined by the switching characteristic of the DSRD and has been measured as approximately 1.5ns with a 5... Show Full Abstract
A solid-state modulator is being developed at the SLAC National Laboratory for ultra-fast broadband beam deflection. The modulator design is based on an opening switch topology that uses Drift Step Recovery Diodes (DSRDs) as the opening switches. The modulator provides nan-second length pulses into a 50 omega load, i.e. a trip line kicker. The rise and fall time of the kicker is primarily determined by the switching characteristic of the DSRD and has been measured as approximately 1.5ns with a 5kV output voltage. A pumping circuit for the DSRD kicker has been developed to drive 200A through the DSRD with a 3MHz repetition rate. Show Partial Abstract
