An internal PIG source was adopted to attain a compact and simple design. Central region electric and magnetic field design will directly affect the beam quality and reliability of the cyclotron in terms of phase selection, beam loss and beam stability. Moreover, a favourable central region will ensure single-turn extraction efficiency. The central region study was based on detailed orbit tracking results, including the beam behaviour in the push-pull RF mode and phase selection and axial focusing in the latest magnetic field and electrical field distribution from calculation. The physical design results of central region beam dynamics are presented here.
