Abstract: A HIGH POWER MICROWAVE BEAM TUBE IS DISCLOSED EMPLOYING AN IMPROVED ELECTRON GUN. THE ELECTRON GUN INCLUDES AN OUTWARDLY FLARED HIGH VOLTAGE ELECTRICAL INSULATOR FOR INSULATING THE ANODE RELATIVE TO THE CATHODE. THE OUTWARDLY FLARED INSULATOR INCLUDES AN EXTERNAL SHOULDER PORTION ENCIRCLING THE FLARED MEBER, SUCH SHOULDER BEING DISPOSED INTERMEDIATE THE LENGTH OF THE FLARED MEMBER AND BEING JOINED TO A PORTION OF THE ENVELOPE OF THE GUN TO BE OPERATED AT A POTENTIAL POSITIVE WITH RESPECT TO THE CATHODE POTENTIAL. A FLUID ENCLOSURE ENCLOSES THE WIDE END OF THE FLARED INSULATOR FOR CONTAINING A FLUID COOLANT IN HEAT EXCHANGING RELATION WITH PORTIONSOF THE VACUUM ENVELOPE OF THE GUN FOR COOLING THE GUN IN USE.

Abstract: Methods for fabricating concave dimpled dispenser cathodes are disclosed. A multicell groove pattern is formed in the concave face of the cathode blank. An array of concave dimples are formed in the cellular regions of the concave emitter face bounded by the cells of the groove pattern. A multicell grid structure is incorporated into the groove pattern. The groove pattern is formable by photoetching, electrical discharge machining or by milling. The grid structure may be brazed into the grooves or merely supported therein in noncontacting relation therewith.
