Abstract :
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.
