In this work, we propose a method of particle acceleration by the electromagnetic wave pulse propagating in the waveguide. The method is based on a “superposition” the electron cyclotron oscillations in the uniform longitudinal magnetic field and their bounce-oscillations in the periodical transverse magnetic field (undulator). Correspondingly, two mechanisms of the electron accelerations by the wave are provided simultaneously, namely, the well-known cyclotron acceleration and the undulator acceleration in the regime of the inversed free-electron laser. The multi-resonance character of this system leads to a chaotic behaviour of the electron motion in the field of the wave. In the process of this motion, electrons can get a very high energy (as compared to the case of the purely cyclotron acceleration by the same wave pulse.
