Abstract
A RF power coupling system has been developed for
future upgrade of input coupling of the RFQ in the SNS
linac. The design employs two coaxial loop couplers for
402.5 MHz operation. Each loop is fed through a coaxial
ceramic window that is connected to an output of a
magic-T waveguide hybrid through a coaxial to
waveguide transition. The coaxial loop couplers are
designed, manufactured, and high power processed. Two
couplers will be used in parallel to power the accelerating
structure with up to total 800 kW peak power at 6% duty
cycle. RF and mechanical properties of the couplers are
discussed. Result of high power RF conditioning that is
performed in the RF test facility of the SNS is presented.
