Abstract: An improved traveling wave tube and method of manufacturing same is disclosed. The tube has an elongated housing with a central evacuated passageway. There are a plurality of beam focusing annular magnets supported within the housing around the passageway at predetermined spaced locations along the length of the passageway and a slow wave circuit supported within the housing in predetermined relationship with respect to the magnets. The housing is a pair of joined semi-cylindrical mating ceramic substrate halves, each half including semi-annular grooves along its part of the passageway which register with respective semi-annular grooves of the other half to define annular grooves which receive and support the magnets. The ceramic substrate halves have conductive material deposited therein that forms the slow wave circuit. The associated method comprises the steps of forming first and second semi-cylindrical substrate halves with rib-like constrictions and recesses for the slow wave circuit and grooves for the magnets, depositing the slow wave circuit in both halves providing magnets in the grooves; and joining the halves together with the grooves and slow wave portions on both halves in registration.
