Abstract
A cathode device includes an emitter tip for generating electrons. An elongate heater is included having proximal and distal ends. The emitter tip can be located at the distal end of the heater. Two spaced apart legs can extend away from the distal end of the heater, terminating at the proximal end and forming an elongate slot therebetween. Two electrical contacts can compressively engage respective opposite outer surfaces of the two legs at the proximal end of the heater to mechanically secure and electrically connect the two legs of the heater to respective electrical contacts at a junction that is at a location spaced away from the emitter tip to keep the junction cooler.
Claims26
A cathode device comprising:
- an emitter element for generating electrons;
- an elongate graphite heater having proximal and distal ends, the emitter element being mounted to the graphite heater in an emitter mount at the distal end, two spaced apart legs extend from the emitter mount, terminating at the proximal end and forming an elongate slot therebetween;
- and
- two electrical contacts compressively engage respective opposite outer surfaces of the two spaced apart legs at the proximal end of the graphite heater to mechanically secure and electrically connect the two legs of the graphite heater to respective electrical contacts at a junction that is at a location spaced away from the emitter element to keep the junction cooler.
