Atmospheric pressure glow discharge micro-plasma jet

Summary form only given, as follows. Atmospheric pressure microhollow cathode discharges (MHCDs) offer the possibility to generate non-thermal plasma by relatively simple means. When operated in rare gases or rare gas-halide mixtures it emits excimer radiation with high efficiency. Operating the discharges in atmospheric pressure air has been shown to allow their use as plasma cathodes for stable large volume atmospheric pressure air plasmas. The plasma results from a direct current discharge between two molybdenum electrodes (0.25 mm thick) that are separated by an alumina insulator of the same thickness.
