The plasma state in the surroundings of a multi-cathode-spot vacuum arc

Mostrar todas las versiones(2)

A stationary, two-fluid model with spherical symmetry to describe the region surrounding the electrodes of a multi-cathode-spot vacuum arc is presented. For typical values of arc parameters, there is a weak coupling between ions and electrons and an analytical approximation for the physical quantiti...
