✦ Synopsis

Classified abstracts 4364-4373 tungsten wire, the initiation of a discharge is found to be dependent on the filament geometry. The effect of connecting the discharge power supply to either the positive or negative leg of the filament is examined. When the emission current becomes a sizeable fraction of the filament heater current, the filament does not emit uniformly. The temperature distribution indicates that the majority of the electrons are emitted from the negative leg of the filament. K W Ehlers and K N Leung, Reo scienr hufrum, 50 (3), 1979, 356-361.
