ABSTRACT:
A fast warm up, die-drawn, low mass cathode cap is substantially cup-shaped having a closed end and an upstanding side wall integral therewith. The thickness of the side wall is less than that of the closed end, permitting more of the heater energy to be concentrated in the closed end which carries, on the outer surface thereof, the electron emissive material.
