Self-modulation suppression in the delayed-feedback klystron-type oscillator via the chaos control method

Self-modulation suppression in the self-oscillator based on a double-cavity drift klystron with delayed feedback via the previously proposed chaos control method is discussed. The numerical simulation and theoretical analysis of a simplified model (point map) demonstrate that the beam current stimulating self-modulation can be increased by a factor of 1.8–2 at the center of an excitation zone when the feedback depth is not changed and, simultaneously, the output power grows by a factor of approximately 1.5. When the phase of the controlling feedback is displaced by approximately π with respect to the value corresponding to the center of a generation zone, the power can be increased by a factor of 3 or more.
