Abstract

Method and apparatus for generating and sustaining a glow discharge plasma in a plasma discharge space comprising at least two spaced electrodes. The method and apparatus are arranged for performing the steps of introducing in the discharge space a gas or gas mixture under atmospheric pressure conditions, energizing the electrodes by applying an AC energizing voltage (Va) to the electrodes, and controlling the energizing voltage (Va) such that at plasma generation a sharp relative decrease of displacement current is provided.
