Abstract :
As part of the Accelerator Production of Tritium (APT) program, a normal conducting (NC)-superconducting (SC) 100 mA continuous wave (CW), 1030 MeV accelerator is being designed. Maintaining the RF cavities in this linac at their proper resonant frequency, rf field amplitude and phase during commissioning (low duty factor pulse mode) and operation (high current continuous beam) is the function of the Low Level Radio Frequency (LLRF) system. This paper describes the linac characteristics that determine the LLRF system requirements with the corresponding control functions, and an overview of the techniques proposed to meet these requirements
