PLASMA STREAMING IN A HIGH-CURRENT CARBON ARC,

Abstract

An experiment was conducted with a high-current carbon arc in nitrogen as a redonfirmation of a theory proposed by H. Maecker in 1955 as an explanation for plasma streaming in high-current carbon arcs. The results obtained verify the theory. An approximation, regarding the effect of an axial hole in a carbon cathode on the current density at the cathode made by Maecker in applying his theory to an experimental situation is shown to be a good one. Data obtained for the diameter of the cathode spot of a carbon arc as a function of current are presented. (Author)
