Cathode Drop of the Potential of a Vacuum Arc of Metals

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

The basic mechanisms of ionization in the cathode spot of a vacuum arc are considered. It is shown that the singly charged positive ions formed here are a result of the collision ionization of the evaporated atoms of a metal by electrons. On this basis the assumption is made that the cathode drop of the potential of the vacuum arc of metals is determined by the energy of ionizing electrons at which the ionization section attains its maximum.
