Excitation of monochromatic longitudinal plasma oscillations in a magnetic field by a beam of oscillators or charged particles traversing the plasma parallel to the magnetic field with a constant velocity, possessing identical Larmor radii and uniformly distributed with respect to azimuthal angle is considered. For glancing'' waves the major mechanism leading to oscillation saturation is the disappearance of resonance between the wave and particle due to variation of the beam particle velocity component along the magnetic field induced by the oscillation field. For oscillations propagating perpendicular to the magnetic field saturation of the oscillations is due to variation of the transverse velocity and of the azimuthal angle of the beam particles. The oscillation amplitudes under nonlinear conditions are estimated for all of these cases. (auth)
