ABSTRACT:
A direct heating cathode includes an emitter for emitting electrons and a generally W shaped heater connected at opposite ends to terminals having a flat portion on which the emitter is mounted, bent portions at opposite sides of the flat portion, and an upwardly projected shoulder portion in the vicinity of each of the ends of the heater. Each of the bent portions of the heater includes two oppositely directed bends between the flat portion and the proximate heater end. The cathode structure elevates the temperature of the cathode at the position of the emitter, reducing power consumption and improving start-up speed, operational stability, and life expectancy.
