On one mechanism of spurious oscillations in high-power gyrotrons

WebPower gyrotrons with evolution of the interaction space are considered for generating stable single-mode oscillations under conditions favoring self-excitation of several modes. Interaction of two modes, occurring in small resonator cavities, can be treated as a suppression of the mode with a smaller initial increment than that with a larger initial … WebThe gyrotron also operates in the second harmonic TE 2,6,1 mode at 456 GHz and in the TE 2,3,1 fundamental mode at 233 GHz. ... After oscillations begin around 77 mA, the power is linear with beam current, indicating that saturation of the interaction has not been reached. A maximum CW output power of 8.4 W is achieved at beam parameters of 135 ... WebOct 1, 2024 · It was shown that the hard self-excitation at the second cyclotron harmonic is possible in the presence of generation at the first one.
