Abstract

The design concepts for ferrite-tuned accelerating cavities discussed differ from conventional solutions using thick ferrite toroids for frequency tuning. Instead, tuners consisting of an array of ferrite-loaded striplines are investigated. These promise more efficient cooling and higher operational reliability. Possible improvements in both voltage holding and average power handling are examined. A variety of options discussed permit substantial improvements on both voltage holding capabilities and tolerable RF power levels of ferrite-tuned cavities for rapid-cycling booster synchrotrons. Layout examples for the SSC-LEB RF system are presented (tuning range 47.5 to 59.6 MHz, repetition frequency 10 Hz).<>
