ABSTRACT:
A travelling wave tube is provided with a slow wave structure consisting of clover leaf cavities in which frequency selective attenuators are present in subsidiary cavities formed within the nose of a clover leaf cavity. Each attenuator consists of dielectric material loaded with attenuation material. The use of the invention enables the coupling properties of the clover leaf cavities and their resonant frequencies to be chosen to provide optimum oscillation suppression.
