Abstract
It was found that arc potential rises discontinously when the separation between two electrodes reaches a critical distance which has a certain functional dependence on the ambient gas pressure and the arc current. This phenomenon is discussed quantitatively as being caused by diffusion of metal vapor from the cathode spot to the surrounding gas in hemispherical geometry.This publication has 4 references indexed in Scilit:
