Abstract
An electron beam collector for a high power electron beam tube has a metallic hollow body for receiving the electron beam, a metallic outer body, and an insulating casing interposed between the inner and outer bodies. A plurality of thin sheet metal fins extend radially outwardly from the outer surface of the hollow body to the inner surface of said insulating casing. The fins are each soldered at their inner ends to the hollow body and at their outer ends to the insulating casing.
Claims15
An electron beam collector for a high power electron beam tube comprising a metallic hollow body, a metallic outer body surrounding said hollow body, and a casing of electrically insulating material interposed between said two metallic bodies, said hollow body comprising a hollow body core and a plurality of longitudinal fins connected with the outer surface of said hollow body, said insulating casing being firmly connected to the outer edges of said fins, each of said fins being formed of sheet metal with a thickness of less than 0.5 mm.
A method of producing an electron beam collector for a high power electron beam tube, said collector having an inner metallic body, an outer metallic body, and an insulating casing interposed between said metallic bodies, comprising the steps of applying a layer of solder to the outer surface of said inner body, surrounding said inner body with a plurality of metallic fins having their edges in contact with the outer surface of said inner body, inserting said inner body and said fins into a hollow tube which has a lesser thermal co-efficient of expansion than the material comprising the inner body and said fins, raising the temperatue of said assembly to soldering temperature for soldering the inner ends of said fins to said inner body, removing said assembly from said tube, machining the outer edges of said fins, providing a layer of solder on the inner surface of said insulating casing, and soldering the outer edges of said fins to the solder layer on the inner surface of said insulating casing.
