Abstract

Prebreakdown current pulses and associated emission from an electrode gap are studied for gaps a few centimeters wide under industrial vacuum conditions. It is found that explosive emission of electrons caused by gap breakdown is preceded by an isolated prebreakdown current pulse. A relationship between the prebreakdown current pulse and explosive electron emission is established. It is conjecture that electron avalanches may develop in thin dynamic layers of desorbed gas and vaporized contaminants supplied from the electrodes.
