  The injector is a 1.7m Sector Focusing Cyclotron (SFC) which consists of a focusing isochronous magnet, a vacuum chamber and PIG, ECR sources as well.

  The weight of SFC magnet is about 250t, fitted with 3 pairs of spiral shims, valley coils and trimming coils. The pole gap between hills is 19 cm with a maximum average field of 1.6T. The extraction radius is 75 cm. The maximum current for the main coil is 1300A with a stability of 1×10-5/8hr.

  The RF resonator is a 1/4 wave length co-axial line with a 180° D box. The maximum accelerating voltage is 100kV excited by a 200 kW transmitter.
