“…We expected these oscillations, which indicate non-self-sustaining character of hollow cathode phase. These oscillations are similar to the one observed [7] previously, when no trigger pulse is used to trigger the switch gap. Such oscillations are minimum in case of trigger pulse type-1, -2, and -3, as the charge content in these trigger pulse types is high (Table I).…”

In this paper, experiments have been reported on finding a possible solution to the current quenching problem in the pseudospark switch (PSS). The charge injection trigger system has been used to investigate this aspect. Trigger current pulses with varying duration and varying charge content have been used for injection of charge from a single dielectric trigger unit into the hollow cathode geometry of the PSS. Quenching has been suppressed in the PSS by optimizing the triggered charge content. This approach has the advantage of using existing switch technologies as well as assemblies for solving the current quenching problem. Possibilities for further work on triggered charge in hollow cathode geometry have been outlined.

Portable autonomous generator of high-power RF-pulses based on the gas discharge with hollow cathode has been designed, fabricated, and tested. Input and output characteristics are the following: discharge current amplitude is 800 A, duration of generated RF-pulses is 350 ns, carrier frequency is ∼90 MHz, power in RF-pulse is 0.5 MW, pulse repetition rate is 0.5 kHz, and device efficiency is ∼25%.
