Emission Characteristics of a Constricted Arc Discharge in a Forevacuum Plasma-Cathode Source of Pulsed Electron Beam

We describe our investigation of the emission characteristics of the constricted arc discharge in a forevacuum-pressure plasma-cathode pulsed electron beam source at gas pressure 5–18 Pa. At low gas pressure the efficiency of electron emission from the constricted arc plasma is rather low, and the e...
