Gradient and shim coils were designed for a high-temperature superconductor magnet system. Particular attention was paid to minimisation of the eddy currents generated in the cryostat of the experimental magnet. The constrained space and requirement for wide wire spacing in the design dictated the use of minimax current density technique which more than doubled the efficiency of the transverse gradient coils.
