Аннотация
The stability of a vacuum arc discharge (VAD) with allowance made for the parameters of an external circuit and a deduced equation of the heterogeneous kinetics of elementary cathode spots (ECSs) in the group cathode spot with one-dimensional configuration is analyzed. It is theoretically and experimentally shown that a VAD with a rising voltage-current characteristic (VCC) is stable independently of the parameters of the external circuit. Stability conditions for a VAD with falling VCC are found.
