The central solenoid (CS) is an important com ponent of China Fusion Engineering Test Reactor,for producing,forming and stabilizing plasma in the superconducting tokamak.It is a complicated work to design and manufacture the large superconducting CS magnet,so it is meaningful to design a central solenoid model coil (CSMC) and analyze its electromagnetic properties in advance.In this paper,the structure,design parameters and magnetic field distribution of the CS model coil are dis cussed.The peak power of radial and axial tu conductors and time bucket loss are analyzed by using piecewise-linear method.The CSMC AC loss with different Nb3Sn CICCs and AC loss of ITER CS coil are compared.The special electrometric method to measure AC loss of the CS model coil for fu ture reference is presented.
