The "Hunting Effect" in the Cathode Region of a Vacuum Arc

Abstract

The interaction of liquid-metal droplets with plasma jets in the cathode region of a vacuum arc is considered based on the ecton model of a cathode spot. It is shown that the heating of a droplet which is in the zone of operation of a cathode spot can result in the transition of the droplet into the plasma state.
