Delay and jitter of pseudospark switch triggered by glow discharge

A type of glow discharge triggered pseudospark switch is designed, and the relationship among the delay and jitter of the switch and the glow discharge current, gas pressure, trigger voltage and anode voltage is studied. When the glow discharge current is less than 0.30 mA, the switch can not be triggered; when the current increases from 0.35 mA to 0.6 mA, the delay and jitter decrease; when the current is about 0.60 mA, the delay and jitter are stable. When the He pressure is lower than 6 Pa, the switch can not be triggered, which is consistent with the theoretic value 6.95 Pa; when the He pressure is between 6 Pa and 12 Pa, the delay and jitter lessen as the gas pressure increases; the switch can work in a stable state when the gas pressure is more than 12 Pa and less than 30 Pa.
