The superconducting coil systems for ITER will consist of 24 toroidal field coils and a central solenoid operating at a field of 13 T as well as a set of 6 poloidal field coils. They will require about 1700 tonnes of Nb3Sn strand in cable-in-conduit form, about 13,000 tonnes of steel structure, and a cryoplant providing for a heat load of 110 kW at 4.5 K. Selected features of the design, the manufacturing process envisioned and of the R&D program are described.
