A Solid-State Nanosecond Beam Kicker Modulator Based on the DSRD Switch
Benwell, Andrew.
A fast solid-state beam kicker modulator is under development at the SLAC National Accelerator Laboratory. The program goal is to develop a modulator that will deliver 4 ns, +/-5 kV pulses to the ATF2 damping ring beam extraction kicker. The kicker is a 50 OMEGA, bi-polar strip line, 60 cm long, fed at the downstream end and terminated at the upstream end. The bunch spacing in the ring is 5.6 ns, bunches are removed from the back end of the train, and there is a gap of 103.6 ns before the next... Show Full Abstract
A fast solid-state beam kicker modulator is under development at the SLAC National Accelerator Laboratory. The program goal is to develop a modulator that will deliver 4 ns, +/-5 kV pulses to the ATF2 damping ring beam extraction kicker. The kicker is a 50 OMEGA, bi-polar strip line, 60 cm long, fed at the downstream end and terminated at the upstream end. The bunch spacing in the ring is 5.6 ns, bunches are removed from the back end of the train, and there is a gap of 103.6 ns before the next train. The modulator design is based on an opening switch topology that uses Drift Step Recovery Diodes as the opening switches. The design and results of the modulator development are discussed.
