Study of the Repetition Pulses Based on Hydrogen Thyratron

Abstract

Repetition pulses with sub-microsecond arising time, high voltage and large current, have been widely utilized in the field of production and scientific research, in which the gas spark switch is usually selected because of the large state current and the high operating voltage. 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 pulses at a high rate. In this paper we proposed a novel design of repetition pulses, in which it gets a several times high voltage output based on the inductive-adder, by using the hydrogen thyratron switch with a low 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 pulses in details
