Abstract: To achieve an optimum reduction of the warmup time of a Wehnelt cathode, by maintaining a good efficiency, it is proposed to use as a cathode a triode system arranged within the usual cathode sleeve, with the inside of the base plate, on the outside of which the electron-emitting layer is deposited, serving as the anode, so that the electron-emitting layer is heated by the anode dissipation of the triode system.

Abstract: In a cathode heater, the portion of the coil adjacent to the emitting surface of the cathode has a smaller pitch or is covered with an oxide coating of lower capacity of heat per unit of length than the distant portion. As a result, the emitting surface is heated-up very quickly, and in a picture tube, for example, the picture comes on after a very short time. The heater according to the invention can be exchanged for a conventional heater without electrical and mechanical changes.
