SNS RING HIGH POWER RF CONTROL SYSTEM

The SNS Ring RF system is a dual harmonic system. Three cavities running with the harmonic h=1 provide 40kV and one cavity with the harmonic h=2 provide 20 kV. Each cavity has two gaps with a design voltage of 10 kV per gap and will be driven by a power amplifier (PA). An Allen-Bradley ControlLogix is chosen for SNS Ring High Power RF (HPRF) controls via Flex I/O interface over the Remote I/O (RIO) network. The details of the system are presented in this paper.
