Contents RF SYSTEM OVERVIEW
The mission of the RF Group is to ensure that precisely controlled RF power is provided to the linac beam in a safe, highly reliable and cost-effective manner. RF Power Systems provide the pulsed energy to accelerate the H-beam to the accumulator ring. Fourteen High Voltage Converter Modulators (HVCM) supply power to twentyfive klystron transmitters used to control the ninety-two klystrons aligned parallel (figure 1) with the linac from the RFQ to the twenty-third cryomodule. Ninety-two Low Level RF (LLRF) systems, each with a klystron in their control loop, maintain the linac cavities at designed field and amplitude [1]. Four additional, but identical, LLRF systems control the four 20 kW triode amplifiers driving rebuncher cavities between the RFQ and the first DTL.
