The SSRL injector kickers

The kicker units for injection and ejection at the new Stanford Synchrotron Radiation Laboratory (SSRL) injector synchrotron are built from two kicker modules driven by compact in-air delay line thyratron pulsers. The kickers have an aperture of 25 mm*60 mm. The injection kicker is 60 cm long (30 cm each module) and bends the 150-MeV electron beam by 42 mrad during injection. The extraction kicker module is 120 m long (60 cm each module) and bends the 3-GeV beam by 4 mrad for extraction. The pulsers produce current pulses on the order of 900A with a fall time of 200 ns for injection, a rise time of 260 ns for extraction, and a pulse length (rise plus flat top time) of 400 ns.<
