High voltage multi-pulse generation by pulse circular transmission

A new method to generate high voltage multi-pulse is described. The Blumlein pulse forming line(PFL) and the pulse transmission line are connected to form a closed loop, in which the voltage pulse generated by the PFL will circulate with the loss neglectable. And if the resistance of the load is much higher than that of the transmission line, the MHz repetition multi-pulse cluster will act on the load. Theory analysis and experiments have been done to prove the feasibility of this method. In the experiments, the multi-pulse clusters were generated with a voltage more than 200 kV, a pulse number more than 4, and a pulse interval less than 400 ns, according with the forecast of the theory analysis.
