Abstract :
The paper presents results of nonstationary two-dimensional hydrodynamic model of vacuum arc emission center-ecton. The numerical simulation was carried out for the initial stage of the operation of the ecton of a low-current vacuum arc on a copper cathode. It was shown that the current flows in the main through the edges of the emission center. A mechanism for the motion of a cathode spot has been proposed
