Abstract :
EAST (HT-7U) is a large fusion experimental device being built at IPP, Hefei, China. Its superconducting magnet system consists of sixteen Toroidal Field (TF) coils and fourteen Poloidal Field (PF) coils. The TF coil includes the winding pack with a square cable-in-conduit (CIC) type superconductor in NbTi cooled by a force flow of supercritical helium, the welded case structure, the gravity support which is composed of pedestals with flexible plates, the coil joint with low resistance at high current and other components. At present, the production of all TF coils has been finished and all of the TF coils have been installed in the machine. This paper describes mainly the special fabrication processes of the TF coil
