Anisotropically loaded helix assembly for a traveling-wave tube

摘要

The present invention is an anisotropically loaded helix assembly for use in a traveling-wave tube, and the corresponding method for making the same. The present invention includes a helix circuit concentrically supported within a conductive cylindrical housing by a plurality of dielectric support members. The present invention effects an improved efficiency and bandwidth in the performance of TWT by the material used to form the dielectric support members, the shape of the dielectric support members and the manner by which the anisotropic load is affixed to the dielectric support members.
