Abstract :
The application of a magnetic field to the discharge gap of a vacuum arc increases the average charge of the ion flow and, with an elevated gas pressure (10-5-10-4 Torr), to the appearance of gas ions in the discharge plasma. The paper presents the results of an experimental investigation into the charge composition of the vacuum arc plasma. A probable physical mechanism for the above changes is discussed
