A New and Improved RF Resonator Segment for the TRIUMF Cyclotron

Programs at TRIUMF directed toward higher currents, separated turns and extraction of H- beam require a resonator structure of greater mechanical stability. Studies have led to the design and installation of a new resonator structure with increased stiffness and reduced vibration amplitude. Measurements with a newly designed segment installed in the TRIUMF cyclotron have led to more accurate determination of the RF leakage power (excitation of RF modes in the beam space).
