Abstract

The problem of the motion of the cathode spot of a vacuum arc electrical discharge in a magnetic field applied tangential to the cathode surface is considered. The treatment is based on concepts of the nonstationary, cyclical nature of processes occurring in the cathode spot and the key role of return electrons falling out of the near-cathode plasma back onto the cathode.
