Abstract
A coaxial TWT comprises a hollow beam gun which injects a thin annular beam between multifilar helices independently supported by thin-walled dielectric sleeves. The beam is focussed by a balanced, coaxial PPM focussing assembly, causing a stable hollow beam flow. The input and output coupling helixes, and the interaction helices which form the slow-wave structure on the exterior and the interior of the hollow beam, respectively, are preferably counterwound with respect to each other to provide greater frequency bandwidth than when similarly wound. Input and output helix coupling to either the inner or the outer helix is possible.
