ABSTRACT:
An improved pole piece structure for periodic-permanent-magnet focused traveling wave tubes is disclosed. In one embodiment, the pole pieces have two fold symmetry and the magnets are arranged about the tube axis in a pattern with two-fold symmetry. This structure accommodates the input or output waveguides while maintaining the symmetry of the magnet placement. This allows the electron beam to remain centered on the tube axis and, therefore, minimizes beam interception. Circuit heating is reduced and the power handling margin of the tube is increased in comparison to conventional TWT structures. In another embodiment, a triangular pole piece configuration is employed, eliminating displacement of the magnets at the coupler and sever cavities and providing a third cooling channel.
