Description
At the electron linac of KEK-STF (Superconducting RF Test Facility), an accelerating
electric field of ±0.1% in amplitude and ±0.1degree in phase is required for
Low-Level RF (LLRF) system. Digital feedback (FB) system is adopted for flexibility
of the FB and feedforward (FF) algorism implementation to accomplish these
requirements. In order to carry out the efficient testing of the control system, rf
system modelling with MATLAB/Simulink library is utilized for the investigation of
the control method and cavity simulator using a FPGA board has been developed.
