The gvosdover effect in a low pressure arc constrained by its own magnetic field

This paper continues the calculations of a preceding one (Theoretical investigation of the first order magnetic self-striction in a low pressure arc with remote walls) and indicates a method for adding the Gvosdover effect (reduction in electron mobility by ion-electron scattering) to the corrections introduced in that paper. The case of mercury vapor is, again, treated as an example. The model predicts the slightly rising volt-ampere characteristics pertaining to related cylindrical arcs, and also shows some discontinuities and instabilities not found in the cylindrical case. This investigation was supported by the Westinghouse Research Laboratories.
