Abstract

One of the central solenoid (CS) designs for the International Thermonuclear Experimental Reactor (ITER) superconducting magnet system is presented. The CS part of this magnet system will be a vertical stack of eight modules, approximately 16 m high, each having approximate dimensions of 4.1-m o.d., 2.8-m i.d., and 1.9-m h. The peak field at the bore is approximately 13.5 T. A cable-in-conduit conductor with Nb₃Sn composite wire will be used to wind the coils. The overall coil fabrication will use the insulate-wind-react-impregnate method. Coil modules will be fabricated using double-pancake coils with all splice joints located in the low-field region on the outside of the coil. All coils will be structurally graded with high-strength steel reinforcement which is cowound with the conductor. Further details of the CS coil design and analysis are described
