Generators of High-Power High-Frequency Pulses Based on Sealed-Off Discharge Chambers With Hollow Cathode

摘要

Repetitively pulsed generators of high-power high-frequency pulses based on sealed-off discharge chambers with a hollow cathode are described in this paper. Pulses of length 100–800 ns and power up to 250 kW at a frequency of 120 MHz with a repetition rate of 100 Hz were obtained using the chamber equipped with a $hbox{H}_{2}$ source. Pulses of length 100–1300 ns and power up to 900 kW at a frequency of 120 MHz with a repetition rate of 100 Hz were obtained using the chamber of similar design and equipped with a $hbox{N}_{2}$ source. The chamber filled with $hbox{H}_{2}$ proved to be more efficient compared to the chamber filled with $hbox{N}_{2}$.
