Multiple Solutions in the Theory of DC Glow Discharges
P. Almeida, and M. Benilov
Departamento de Física. Universidade da Madeira, Portugal
It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present work, these solutions have been calculated for the first time with COMSOL Multiphysics.
