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.
