Abstract
A split-ring resonator of 
designed for use in the Stony Brook heavy-ion booster has been developed and tested. The resonator, operating at 150 MHz and with an effective length of 21 cm was constructed of OFHC copper and electroplated with lead. Losses of 8.5 W at an accelerating field of 3.0 MV/m and 11 W at 3.25 MV/m were obtained; the resonator could be operated continuously up to at least 3.5 MV/m without breakdown or thermal run-away. Vibration-induced frequency excursions were found to be small (∼ 20 Hz pp). Under these conditions the split-ring resonator was electronically stabilized to an accuracy of 0.005 radian at 2.5 MV/m.
