Abstract : The slow-wave approximation is used to derive the dispersion relation for a uniform, finite, solid electron beam in a concentric tunnel. A finite, longitudinal magnetic field is used to focus the beam. Radial and longitudinal propagation constants are computed for modes with axial symmetry. The propagation constants and the plasma frequency reduction factor are presented in a novel, graphical form which allows construction of the Brillouin diagram in a simple straightforward way. A number of representative Brillouin diagrams are shown, and the modes are classified in accordance with their characteristics. (Author)
