Abstract

Self-organized anode patterns were observed on the surface of a liquid or metal anode when an atmospheric dc glow discharge with helium flow was generated. The pattern formation depends on current, gap length, and helium flow rate. With increasing discharge current or gap length, an anode luminous spot changed to self-organized patterns. In the case of using a liquid anode, anode pattern formation depends on liquid conductivity.
