Normal mode and their high-frequency instabilities are analyzed self-consistently considering electron beams propagating along a magnetic field in unbounded and bounded systems. For unbounded dielectric system, the beam couples with electromagnetic waves corresponding to X and O modes, resulting in the slow cyclotron and Cherenkov instabilities, respectively. For cylindrically bounded system, a self-consistent field theory is developed. Axisymmetric and nonaxisymmetric normal modes obtained are hybrid modes. Cherenkov instability for the EH mode and slow cyclotron instability for EH and HE modes are confirmed in a cylindrical slow wave structure system.
