Abstract

Abstract

Hydrogen thyratron still plays an important role in the field of high voltage and high current technology, how to adjust the working parameters of thyratron is an important topic in pulse modulation technology. The performance and life of thyratron depend on thyratron trigger to a great extent. To optimize the performance of thyratron and make it preionize more sufficiently, the high current pulse preionization technology is adopted by analyzing the thyratron triggering characteristics. A thyratron double pulse trigger based on kicker pulse power supply of China spallation neutron source is developed. The trigger has excellent performance such as nanosecond rising edge, low jitter and high current output. The effects of different reservoir heater current, cathode heater current and pre-ignition parameters on the thyratron state are studied, aiming at the problem of mis-conduction and leak conduction of thyratron, a detection circuit based on monostable circuit and CMOS gate circuit is developed, which can accurately analyze and predict the state of thyratron. Finally, the fault of kicker pulse power supply system is analyzed and summarized annually.
