Hollow Cathode Discharge with Thermionic Cathodes

Journal of Applied Physics, 1971
The electrical and visual characteristics of a dc hollow cathode discharge with indirectly heated thermionic cathodes were obtained in argon at a few Torr. Two facing planar cathodes of variable separation form the hollow cathode geometry. A hollow cathode effect was observed in the ``ball-of-fire'' mode and in the ``low-voltage arc'' mode. The results

Cathode Sputtering in Hollow Cathode Discharges

Journal of the Physical Society of Japan, 1962
In order to investigate the processes responsible for a negative resistance of the hollow cathode discharge, several discharge parameters are measured with a Langmuir probe. The vapor density distributions of the sputtered cathode metal are measured by the absorption method of the resonance radiation of the metal atom. Almost all the metal atoms in the
