Abstract: 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.

Abstract: The present invention relates to methods 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. Alternative phase shifters are shown.
