Abstract

Development of RF power coupling system for a radio frequency quadrupole (RFQ) accelerating structure for operation at 402.5 MHz is presented. The system employs two coaxial loop couplers for reliable operation. Each coupler has a coaxial loop antenna that is fed through a coaxial alumina ceramic window. The two coaxial couplers are fed through a waveguide magic-T hybrid junction used as an in-phase power splitter with isolation. The coaxial ceramic window design is virtually identical to the design of the windows used in the SNS superconducting RF (SRF) cavities operating at 805 MHz that have shown superb performance. Results of RF simulations, electrical and mechanical designs, manufacturing, and high power testing are discussed.
