Dynamical analysis of a helium glow discharge. I - A model
Résumé
In this Letter, we investigate a model elaborated by Wilke et al. to explain various regimes observed in a helium glow discharge [Phys. Lett. A 136 (1989) 114] for which the underlying dynamics can be chaotic, quasi-periodic, etc. We found that this model does not obey all the required physical principles. A new one is therefore proposed. It is mainly based on separated balance equations for charged species resulting from the propagation of ionization waves
