High voltage nanosecond generator with pulse repetition rate of up to 1,000 p.p.s.

A compact high voltage nanosecond generator is described with pulse repetition rate of up to 1,000 p.p.s.. The generator includes a 30-0hm coaxial forming line charged by a built-in Tesla transformer with high coupling coefficient, and a high voltage (N2) gas gap switch with gas blowing between the electrodes. The maximum forming line charge voltage is 450 kV, the pulse duration is ∼ 4 ns and its amplitude for a matched load is up to 200 kV.
