Abstract:
1. A method of generating an atmospheric pressure glow discharge plasma (APG), wherein said plasma is generated in a discharge space formed between at least one first electrode surface and at least one second electrode surface, said method at least comprising the steps of supplying a gaseous substance to said discharge space and powering said first and said second electrode surfaces for generating said plasma, wherein said step of supplying a gaseous substance to said discharge space comprises providing a main gas supply stream through a main gas inlet for supplying said gaseous substance and providing a plurality of intermediate gas supply streams through a plurality of intermediate gas inlets from a plurality of second electrode surfaces for refreshing said gaseous substance throughout said discharge space,—wherein said main gas supply stream has a flow greater than the intermediate flow that is sufficient for carrying the plurality of intermediate gas supply streams along with and forcing the plurality of intermediate gas supply streams in a direction along said first and second electrode surfaces, for preventing the establishment of vortices and wakes in said discharge space.
