Superconducting magnet systems in EPR designs

Consideration is given to toroidal field coils, generally designed for an axial flux density of 3-6 T, noting the parameters of several potential designs. The article also discusses poloidal field coils with reference to the heating and equilibrium field windings, operating cycles, and flux density swing in the core. The mechanical structure necessary for the support of inside poloidal coils is described and possible failure modes are identified. Design studies are outlined in terms of toroidal shapes and associated strains, safety discharge, cooling procedures, component reliability, power supplies, and tokamak scaling. Recommendations are made for future research.
