    Spark Gap Trigger Systems

    Despite the many advances intechnologies ranging from IGBTs tomagnetic switching, there is simplynothing else that can achieve the“speed” of the pulse from a spark gap-switched system. North Star HighVoltage offers spark gap driver systemsfor general purpose use. These unitsconsist of a fast-risetime transformerand solid state switch combination.

    The driver system is designed for usewith “midplane” gaps such as thoseused in Marx generators and also foruse with“trigatron style” spark gaps. Risetimes below 300 ns are desirable toachieve multiple gap switching in Marx

    generators and low jitter triggering with other spark gap switches.

    The risetime of the trigger generator depends on capacitive loading, but can be as shortas 200 ns (10-90) when driving < 15 pf. Superior noise isolation is provided by fiberoptic triggering. The triggers are all supplied with passive BNC/fiber converters andfiber optic cables in order to eliminate spurious triggering. A monitor fiber which lightswhen charged is also provided for convenience.
