Manufacturing Status of CFETR Central Solenoid Model Coil

A central solenoid model coil (CSMC) is to verify the large-scalar superconducting coil manufacture technology for China Fusion Engineering Test Reactor (CFETR) in Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP). The CSMC composed of Nb₃Sn and NbTi hybrid superconducting magnet can reach to 12 T maximum magnetic field. The main manufacturing processes of the coil are developed and verified by R&Ds and mockup coil fabrication. For now, all the five coils winding and 2/3 of terminals fabricating are finished, and the heat treatment for the Nb₃Sn inner coil is completed. The turn releasing and insulation wrapping process and station for the heat treated Nb₃Sn coil has been developed. The major remaining processes for the five coils are ground insulation wrapping and vacuum pressure impregnation (VPI). The mockup coil VPI will be performed firstly to validate the process. This article introduces the main manufacturing progress of the CFETR CSMC.
