Primary energy source of high repetition rate compact accelerator

This paper introduces the design and experimental study of the primary energy source of an accelerator which can produce high power pulses (up to GW level) of duration about 6 ns, and repetition rate controllable from 1 to 300 Hz. The primary energy source is powered by a commercial three-phase AC power supply, rectified by semiconductor devices, and resonantly charges the Tesla transformer controlled by solid switches and relays. The experimental results indicate that this system can produce repetitive high voltage pulses (up to 300 kV) at a 120 Ω load through the Tesla transformer and operates stably. Meanwhile, this source takes the advantage of self-shutoff of the thyristors to realize energy recovery.
