Abstract :
The ISAC RF system consists of a radio frequency quadrupole accelerator, five drift tube LINACs, six bunchers, two choppers, and a bunch rotator. An additional buncher will be added in the near future. They run at frequencies ranging from 5.89 to 106.08 MHz, and have cavity Q values ranging from 400 to in excess of 5000. All have to run synchronously and be individually amplitude and phase regulated. A novel system that provides closed-loop amplitude, phase, and tuning control for each cavity using a single feedback circuit is employed. This system, as well as the frequency synthesis and distribution system, is described in this paper
