Abstract. Dynamics of excitation of fast cyclotron wave of electron beam was studied in double-resonator accelerator of electrons with cyclotron resonance a well as an influence of phase of input microwave oscillations. Numerical simulation of wave excitation processes showed the possibility of highly efficient acceleration of electrons if microwave power would be introduced simultaneously into both resonators of the device. The results of modeling a device with a low RF power level are consistent with the conclusions of the analytical theory for a filamentary electron beam. While maintaining cyclotron resonance conditions in a magnetic field being constant over the length of the device, the best in this case is the coincidence of the phases of RF oscillations in both resonators. In the case of high input power, special attention must be paid to the choice of the optimal profile of the magnetic field along the length of the accelerator and to the deceleration of the beam arising induced by the radial components of the converging magnetic field. Deviations from cyclotron resonance conditions at the accelerator length may result in a non-zero optimum phase shift of microwave oscillations in the resonators. It has been shown that by reducing the beam current in a double-resonator accelerator, it is possible to significantly increase the energy of accelerated electrons while maintaining the RF power level at the inputs.
Key words: accelerator of electrons, cyclotron resonance, fast cyclotron wave.
