AbstractThe design of the ITER magnet system is being finalized. The reference design of the winding pack of the TF coil is based on the use of circular conductors supported by radial plates. This design has been chosen for its high insulation reliability during operation. The overall TF coil structure includes pre-compression rings made of unidirectional fiber glass, which reduce the stress level in the outer intercoil structures and the coil case. The design of the central solenoid, including pre-load structure, has been developed. Two conductor jacket options are still under investigation for the CS and the final choice will be based on the results of on-going R&D.
