The concept design of CFETR (China Fusion Engineering Test Reactor) was started in 2012 in two stages. For CFETR-Phase I, the major radius is 5.7m, minor radius is 1.6m and the magnetic field at plasma region BT is 4-5T. There were 16 toroidal field coils and 6 central solenoid coils designed by Nb3Sn CICC with the maximum operation current of 64 kA and 50 kA, respectively. Three types of plasma equilibrium configuration-ITER-like, super-X and snowflake were designed. The maximum flux provided by the central solenoid is set at 180 volt second. However, to get much higher operation parameters such as steady-state operation,the superconducting magnet system of CFETR-phase II has been updated based on the larger machine with R = 6.7m, a=2.0m, BT= 6.5-7T.Hybrid TF coils are designed by high performance Nb3Sn conductor, which's maximum magnetic field can reach to 14-15 T. Besides, in order to save the space for blanket system and get higher flux, high temperature superconducting Bi-2212 magnet with better current carrying performance under high field is supposed to be employed for the CS coils of CFETR. The Bi-2212 CICC conductor sample has been tested at 4.2 K with criti-cal current of 26.6 kA under its self-field.
