ABSTRACT:
An air-cooled electron tube comprises an envelope including an anode forming a section thereof. A plurality of discrete radiator fins having a proximal end and a distal end are disposed so that the proximal end of each fin is adjacent to the anode. A radiator band having an interior surface circumscribes the radiator fins so that the interior surface of the band is adjacent to the distal end of the fins. The band includes at least one projection, and preferably two, formed around the interior surface of the band. The projection is raised about 0.38 mm above the interior surface and terminates in a sharp edge which pierces the distal ends of selected ones of the radiator fins so as to contact the distal end of each of the fins, thereby urging the proximal ends of the fins into contact with the anode.
