We investigated experimentally characteristics of an atmospheric pressure glow discharge(APGD) produced by cathode-pin and anode-plate electrodes with a flowing gas between the electrodes. An APGD is sustained by DC voltage applied between these electrodes with main and auxiliary gas flow. The nozzle position of the auxiliary gas flow is varied between the two electrodes. It is found at first time that the glow discharge current increased significantly when the auxiliary nozzle is set near the anode plate. This finding is very important to clarify the mechanism of a flow-stabilized APGD.
