Abstract

The theoretical and numerical analysis are presented concerning the conditions at which the charged particles of different initial velocity can be accelerated to the significant kinetic energy in the circularly polarized laser or maser beams and a static coaxial magnetic field. The studies are carried out using the analytically derived equations for the particles dynamics and theirs kinetic energy. The presented illustrations enabled interpretation of the complex motion of the particles and possibilities of their acceleration. At the examples of an electron the kinetic energy and trajectory as a function of the acceleration time at the resonance condition are illustrated in the appropriate graphs. The increase of the particles initial velocity results in the reduction of the coaxial magnetic field intensity at the resonance condition. This field intensity reduction rises with the velocity of the preaccelerated particles..
