TRIGGER DEVICES FOR PSEUDOSPARK SWITCHES

Effective triggering of pseudospark switches with long lifetime and lo w jitter remains an important problem. This paper presents results of investigations of trigger methods for pseudospark switches, based upon pulsed glow discharges in planar and hollow electrode geometry for ch arge injection. The influence of different wiring and geometries of th e electrodes for preionization is investigated. The effect of addition al blocking potentials in the hollow cathode to improve different trig ger systems was measured. Calculations of the static potential in the hollow cathode with or without blocking potential are compared with pa rameters of the discharge.
