Abstract :
First experimental studies of the nonstationary phenomena in a powerful K-band gyro-backward-wave oscillator with an external reflector are presented. Variation of the self-modulation frequency from 69 to 112 MHz and transition to the chaotic oscillations with spectrum width of 100 MHz were obtained due to the tuning of the guiding magnetic field. These results are in a good agreement with simulations, which demonstrate a strong dependence of the system dynamics on the strength of the magnetic field
