Patent ID: 7786675

Claim:
A system for controlling a particle accelerating device comprising a: a plurality of klystrons for generating RF power to be used by the particle accelerating device; and a plurality of delivery systems for delivering the RF power from the plurality of klystrons to a plurality of superconducting cavities, each delivery system further comprising: a circulator which receives the RF power, wherein the circulator is operatively coupled to one of the plurality of klystrons; a ferroelectric phase shift controller which receives the RF power from the circulator, and modifies at least one of a plurality of characteristics of the RF power, the ferroelectric phase shift controller having a waveguide coaxial transformer; an impedance transformer; a housing surrounding the impedance transformer, wherein an opening is formed between an inner surface of the housing and the outer surface of the impedance transformer; a ferroelectric ring disposed in the opening between the inner surface of the housing and the outer surface of the impedance transformer; and a matching alumina ring disposed adjacent the ferroelectric ring, the matching aluminum ring being disposed in the opening between the inner surface of the housing and the outer surface of the impedance transformer; and a plurality of superconducting cavities operatively coupled to the waveguide transformer, wherein the plurality of superconducting cavities accelerate particles in the particle accelerating device.
