A two-dimensional self‑consistent analysis of a dc glow discharge, including a quantitative study of the transition between normal and abnormal regimes, is presented. The model couples a macroscopic description of electron and ion kinetics with Poisson’s equation under specified boundary conditions. The numerical method shows that radial electric fields at the plasma‑sheath boundary draw electrons toward the center of the negative glow and repel positive ions, thereby stabilizing the discharge in the normal regime and emphasizing radial effects.
A two-dimensional self-consistent analysis of a dc glow discharge is presented. The model is based on a macroscopic description of the electron and ion kinetics coupled with Poisson’s equation for a given set of boundary conditions. This numerical method has been used to analyze the basic properties of a dc glow discharge, with a particular emphasis on radial effects. It is shown that the radial electric field at the plasma-sheath boundary tends to draw electrons towards the center of the negative glow and positive ions away from it; the stability of the discharge in the normal regime is due to this radial electric field. A quantitative and self-consistent study of the transition between the normal and abnormal regimes of a dc glow discharge is presented.
