Abstract

Summary form only given, as follows. Reducing the cathode hole diameter to about 100 /spl mu/m makes it possible to extend the pressure range for hollow cathode discharge operation to atmospheric pressure. For a submillimeter hollow cathode discharge in neon (at 100 Torr) it was shown that the flow of material in the cathode transforms the originally, cylindrical cathode hole into a spherical cavity. This self-forming phenomenon leads to an unusually stable and reproducible discharge. Possible applications for miniature hollow cathode discharges and discharge arrays, such as flat panel displays and large area light sources have been considered.
