    Notes: We have achieved phase-locked operation of a module consisting of up to seven relativistic magnetrons. The magnetrons are connected by waveguide in a peer/peer configuration, with no one magnetron acting as a master oscillator. The signals used for coupling are each a substantial fraction of a magnetron's radiated power. Total extracted power, at 2.8 GHz, was 2.0 GW with four magnetrons and 2.9 GW with seven. Several interconnection geometries were explored. One particular geometry was found to produce qualitatively better phase-locked operation than any other. This was in agreement with the predictions of a numerical model of the magnetrons as coupled van der Pol oscillators.

    Interaction of a vircator microwave generator with an enclosing resonant cavity (1987)

    Notes: Interaction between a vircator microwave generator and a resonant cavity is produced by enclosing the virtual cathode inside a right circular cylinder. By varying the cavity length, frequencies corresponding to the TM01n cavity modes are tuned to resonate with the broad- band oscillating virtual cathode. Nonresonant frequencies are suppressed, decreasing the bandwidth of the emitted radiation by a factor ≥5. Measured microwave power is about 4 times that from a detuned cavity.

    Phase locking of high-power microwave oscillators (1989)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 65 (1989), S. 861-866

    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.

    Dynamics of a virtual cathode oscillator driven by a pinched diode (1986)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 29 (1986), S. 3873-3880

    Notes: A new method is demonstrated for extracting radiation from a virtual cathode oscillator in transverse electric (TE) waveguide modes. The dominant radiation mechanism occurs in the region of the virtual cathode, and is not due to reflexing of electrons. Microwave radiation occurs simultaneously or just after beam pinching in the diode. Electrostatic signals show simultaneous occurrence of the virtual cathode and microwave radiation. At the same time, the electron population divides into a beam population and a reflexing electron population. Inhibition of pinching by an axial guide field suppresses microwave radiation.
