Abstract
A high‐pressure glow discharge in flowing gases is described. The cathode surface and the discharge glow are isolated by a mica sheet with a matrix of holes drilled into it. The cathode is differentially pumped to a pressure of approximately 1 Torr. This electrode structure has produced a discharge power density of 15 W/cm3 when the gas residence time is 3 ms.Keywords
