Fast warm-up cathode assembly

摘要

A fast warm-up cathode comprises a solid core body having a heater wrapped thereabout. One end of the core is provided with a widened area of cathode nickel alloy and has on an upper surface thereof an electron emissive material. The opposite end of the core can be provided with a support member which can be fixed into an electrically insulating body. Additionally, electrically conductive legs can be also positioned within the electrically insulating body to provide attachments for the heater.
