ABSTRACT:
A broad-band traveling-wave tube is provided, which contains a cylindrical waveguide made of a plurality of pole pieces and a plurality of spacers alternately arranged along its axis. A helix is placed in the waveguide to extend along the axis of the waveguide. The helix is held by helix supports not to be contacted with the waveguide. The inner wall of the waveguide has a plurality of offsets arranged at intervals along the axis of the waveguide. A bore-diameter-varying portion can be created inside a waveguide without mounting vanes.
