Abstract(s)
Stability of different axially symmetric modes of current transfer in dc glow discharges is
investigated in the framework of the linear stability theory with the use of Comsol
Multiphysics software. Conditions of current-controlled microdischarges in xenon are treated
as an example. Both real and complex eigenvalues have been detected, meaning that
perturbations can vary with time both monotonically and with oscillations. In general, results
given by the linear stability theory confirm intuitive concepts developed in the literature and
conform to the experiment. On the other hand, suggestions are provided for further
experimental and theoretical work.
