Electron density fluctuations accelerate the branching of positive streamer discharges in air
Electron density fluctuations accelerate the branching of positive streamer discharges in air
Branching is an essential element of streamer discharge dynamics. We review the current state of theoretical understanding and recall that branching requires a finite perturbation. We argue that, in current laboratory experiments in ambient or artificial air, these perturbations can only be inherited from the initial state, or they can …
