Abstract : According to the invention, the geometry of the corona discharge system is chosen to provide supersonic flow at the corona edge such that the first strong expansion wave travels downstream toward the attractor nozzle tip to provide a region of high pressure, constant gas density and a corresponding high electric breakdown strength. In order to make it possible then to establish corona, a step is provided on the corona electrode so that as the gas expands over the edge a local region of low pressure, substantially constant gas density is created to provide a region of low breakdown strength favorable for corona.
