Abstract :
A tuning plunger and an adjustable RF coupler have been designed at AECL´s Chalk River Laboratories for a CW 2856 MHz RF cavity for the MIT-Bates South Hall Ring. The tuner provides a frequency range of 1.1 MHz with a frequency resolution of less than 0.5 kHz. The high-power RF drive coupler uses iris coupling and a set of coupling factor (β) adjustment posts to provide fixed β-values from 1 to 10. This paper describes the RF design, mechanical design and performance of these units
