Abstract:

An electron eam in the presence of an axial magnetic field supports four transverse waves-t o cyclotron waves and two synchrono s waves. A general coupling theory is developed from an electronic equation and a circuit equation to describe how these waves can be coupled to traveling-wave circuits. The polarization and power flow characteristics of the waves are derived and substantitated by physical arguments. This theory is applied to the bifilar helix, a circuit which can couple selectively to each of the four modes. A bifilar helix traveling-wave tube was used to investigate experimentally these four beam modes and provide a quantitative check of the coupling theory. Author
