Cathode Plasma Expansion at Early Vacuum Arc at Pulsed Plasma Emission
摘要
The paper focuses on the kinetic modeling of the vacuum arc initiation at the pulse-periodic plasma emission from the cathode surface. A comparative analysis is given to the pulse-periodic and continuous plasma emission from the cathode. An in-depth study concerns the mechanism of the anomalous acceleration of ions and cathode plasma expansion at a short-time emission current switch over, matching the plasma emission and its interruption.
