Abstract:
An improved cathode structure for high current, low pressure electric discharge devices is described as comprising an oxide emissive mix coated filament mounted axially within a hollow open-ended refractory metal cylinder. Unusually high discharge currents on the order of 2 to 50 amperes are provided with this electrode structure for long periods of time.
