Abstract

The apokamp discharge is an atmospheric pressure plasma jet generating from the bending point of the discharge channel between high-voltage and floating potential electrodes. The jet propagates perpendicularly to the interelectrode discharge channel for several centimetres without gas convection. Based on the simplified plasma-chemical model of the discharge, a theoretical explanation of the apokamp phenomenon was obtained for the first time. It is shown that the apokamp is a stable plasma quasi-jet formed by the positive streamer mechanism.
