A system and method of operating a magnetron power source can achieve a broad range of output power control by operating a magnetron with its cathode voltage lower than that needed for free running oscillations (e.g., below the Kapitsa critical voltage or equivalently below the Hartree voltage) A sufficiently strong injection-locking signal enables the output power to be coherently generated and to be controlled over a broad power range by small changes in the cathode voltage. In one embodiment, the present system and method is used for a practical, single, frequency-locked 2-magnetron system design.

Subcritical-voltage magnetron RF power source

A method and system for beam deflection. The method and system for beam deflection comprises a compact superconducting RF cavity further comprising a waveguide comprising an open ended resonator volume configured to operate as a trapped dipole mode; a plurality of cells configured to provide a high operating gradient; at least two pairs of protrusions configured for lowering surface electric and magnetic fields; and a main power coupler positioned to optimize necessary coupling for an operating mode and damping lower dipole modes simultaneously.

Superconducting multi-cell trapped mode deflecting cavity

A low-voltage, multi-beam, multi-MW RF source that operates at a voltage less than or equal to approximately 60 kV and generates at least one MW. The RF source includes a cathode configured to generate a plurality of beamlets. An input cavity and output cavity are common to the plurality of beamlets. A plurality of gain cavities are provided between the input and output cavities, each having a plurality of openings corresponding to the plurality of beamlets. The power source may further include a plurality of cathodes, each cathode generating a plurality of beamlets, wherein the input and output cavities are common to the plurality of beamlets from each of the plurality of cathodes, and a separate set of gain cavities are provided for each cathode. A single cathode version generates approximately 2.5 MW, and a four cathode version having four independent cavity systems and a common magnetic system generates approximately 10 MW.

Low-voltage, multi-beam klystron

A method and systems for fast ferroelectric tuning of RF power used in a particle accelerating system. By adjusting the voltages fed to the ferroelectric phase shift controller, the amplitude and phase of the RF power wave are altered, thus changing the coupling of the power generating circuit and the superconducting cavity. By altering this coupling rapidly, maximum power transfer efficiency can be achieved, which is important given the large amounts of power shunted through the particle accelerating system. In one embodiment, the ferroelectric tuner is optimally made of a magic-T waveguide circuit element and two phase shifters, although other implementations of the system may be utilized.
