Temporal measurements of an accelerated electron flow from area of a vacuum arc

Abstract

Temporal behavior of a high-energy electron flow from area of a vacuum arc was explored. Electrons emanating from area of the cathode with the energies essentially exceeding a voltage drop on the discharge are revealed. Correlation of cruption outbursts of a high-energy electron flow and instabilities of a current of the discharge is revealed. Joint oscillograms of a flow of electrons under different directions to the cathode surface also were obtained.
