Self-Organization Pattern in the Anode Spot of an Atmospheric Glow Microdischarge using an Electrolyte Anode and Axial Miniature Helium Flow

An atmospheric glow microdischarge is generated with an electrolyte anode and axial miniature helium flow. A stable operation under atmospheric pressure can be achieved using an axial miniature helium flow. When the electrode separation is 10 mm and the discharge current is greater than 30 mA, self-organization patterns, which depend on the electrolyte anode concentration, are observed at the electrolyte anode surface, indicating that the anion and cation in electrolyte solution are important for electrolyte anode discharges.
