Investigations of pre-breakdown phenomena: streamer discharges
Abstract:Physical principles of electrical breakdown are reviewed in this article. The phenomena of streamer formation and spontaneous branching are studied in terms of a fluid description based on kinetic theory. Particular attention is paid to a minimal model which is suitable for non-attaching gases. The evidence that anode directed fronts can branch due to a Laplacian instability is shown. Finally an electric shielding factor is introduced which allows us to extend previous results to curved geometries.
