Compact 1000 pps high-voltage nanosecond pulse generator

A compact high-voltage nanosecond generator is described with pulse repetition rate of up to 1000 pps. The generator includes a 30-Omega coaxial forming line charged by a built-in Tesla transformer with high coupling coefficient, and a high-voltage (N-2) gas gap switch with gas circulating between the electrodes, The maximum forming line charge voltage is 450 kV, the pulse duration is similar to 4 ns, and its amplitude for a matched load is up to 200 kV, The generator has been applied to create powerful sources of ultrawide-band electromagnetic radiation and nanosecond microwave pulses.
