Abstract: The design goals of a 20 GW/100 Hz repetitive pulsed accelerator are: output power exceeding 20 GW, pulse width about 40 ns, and repetition rate ranging from 1 to 100 Hz. General design of the device based on Tesla technology is described in this paper. For charging the forming line, a Tesla transformer with open magnetic core is used, whose efficiency exceeds 75% by optimization. The output power of the device reaches 22.6 GW at 100 Hz repetition rate, and operation experiments have verified reliability. The device is was mainly applied to generating intense current. It can also be applied to mechanism researches of the intense current diode and high power microwave.
