Abstract	This paper describes an innovative design for a compact, high repetition-rate trigger generator. The basic circuit and its operation are discussed. Solid state switching and magnetic pulse compression enable the design to operate at rep-rates in the tens of kHz and to be fabricated in a small, compact volume. A breadboard model has been designed and fabricated which can produce an open circuit voltage of up to 40 kV. Two stages of magnetic pulse compression are used along with two pulse transformers to step up the voltage from the primary energy storage elements (at /spl tilde/ 400 V) to the final output voltage of 40 kV. In addition, an energy recovery circuit is used to absorb and recover reflected energy from the typical collapsing impedance load, which would otherwise be dissipated as heat in the other components as well as interfere with the repetitive operation of the pulser. Finally, test results from this breadboard trigger generator are presented, including demonstrated operation at rep-rates of up to 20 kHz.
