The values of the parameter q = 2ω2pe/ω2ce were calculated at which the condition of stationary cyclotron resonance is obeyed for electrons, positrons, and positive and negative ions. Relationships between the azimuthal number m and the resonance multiplicity n, which are necessary for a stationary cyclotron resonance to occur, have been determined. We have found the integral of the drift motion equations which determines the variations of the particle trajectory parameters in the non-neutral plasma subjected to the action of a small-amplitude electrostatic wave under the cyclotron resonance conditions. These variations can be substantial and force the particles to go outside the plasma. It is shown that, under the cyclotron resonance conditions, the considered drift motions can invoke an anomalous radial transport of particles in non-neutral-plasma devices. |
