Annotation
Linear electromagnetic interactions of rectilinear electron beams with magnetoactive plasma in a coaxial waveguide are considered. Dispersion equations are derived and field structures of surface plasma waves in the absence of the electron beam are determined. Dispersion equations of beam waves in the absence of plasma waves are derived. Dispersion equations that describe the interaction of plasma and beam waves are derived. Instability increments in regimes of single-particle and collective Cherenkov effects and irregular Doppler effect are calculated.
