    Notes: Observations of mode selection, frequency locking, and phase locking of a high-power, S-band, cavity vircator oscillator by an externally injected, relativistic magnetron are reported. The injected electric field can increase the virtual cathode oscillation growth rate and defeat chirping. The peak power extracted from the driven vircator cavity is between 100 and 500 MW. The output power from the magnetron is comparable. The virtual cathode oscillation frequency is pulled to the magnetron frequency in 3–5 ns. Locked phase measurements versus the allowable frequency detuning that yields locking agree with predictions. The output power of the driven cavity vircator is two to three times that obtained from a free-running, undriven vircator.

    Phase locking of high-power microwave oscillators (1989)

    Notes: Phase locking is considered both for a case in which an oscillator is driven by an external signal without feedback, and for a case in which two coupled oscillators drive each other. A comprehensive sustained oscillator model is used for the driven microwave cavity. The new locking conditions for two coupled oscillators show that phase locking can occur only when the connector contributes the zero or π phase delay. Temporal behavior is solved numerically. Calculations with large priming power agree with the experiments on a high-power magnetron driven vircator in which there is no feedback to the magnetron. The mutual drive calculations also agree with the experiments on high-power coupled magnetrons.
