ABSTRACT:
A magnetron includes an evacuated envelope having an output dome insulator affixed to a conductive annular output support ring. The output support ring has a substantially flat support surface adjacent to the output dome insulator and a step-like peripheral sidewall which includes a first portion and an outwardly extending second portion. A weld flange circumscribes the output support ring and is attached to the second portion of the peripheral sidewall. A conductive annular radio frequency gasket is disposed on the flat support surface of the output support ring. The structure is improved by the inclusion of a plurality of gasket retainers disposed around the periphery of the r.f. gasket. Each of the gasket retainers comprises a continuous elongated strip of substantially flat resilient material bent to form a substantially V-shaped envelope engaging portion. The envelope engaging portion of each of the gasket retainers includes a long leg section extending along the first portion of its peripheral sidewall of the output support ring and a short leg section which is contiguous with the long leg section and is in contact with the weld flange circumscribing the output support ring. Each of the gasket retainers further includes a gasket engaging portion contiguous with the other end of the long leg section for contacting and retaining the r.f. gasket against the flat support surface of the output support ring.
