Inductive adder based method for generating electromagnetic pulses with controllable timing

Repetition pulse with sub-microsecond arising time, high voltage and large current, has been widely utilized in the field of production and scientific research, in which the gas spark switch is usually selected. However, due to the recovery property of gas ionization, it is hard to get the repeated switch-on and switch-off at a high rate towards the conventional gas spark switch. Owing to the reliably triggering and faster arising time, the hydrogen thyratron is found to be more suitable for the switch to generate the repetition pulse at a high rate. In this paper we proposed a novel design of repetition pulse, in which it get a several times high voltage output based on the inductive-adder, by using the hydrogen thyratron switch with an operating voltage, and then we analyze the magnetic field distribution under the structure of the coaxial cable and describe the design of high voltage repetition pulse in details.
