Acceleration with Digital RF Control System

Abstract

We have developed a digital RF control system with DDS (Direct Digital Synthesizer) for HIMAC (Heavy IonMedical Accelerator in Chiba) synchrotron. In advance, this control system with beam feedbacks was tested in TARN–II ring successfully with very low beam intensity. Now, this tested acceleration system is operating in HIMAC synchrotron with good condition; we found there is no need to use the tested beam feedback system.
