15-N-NM-3206 A reduced length, high field strength magnet, comprised of a number of superconducting magnet coils has ferromagnetic compensation rings positioned coaxially around the magnet bore axis to reduce axial inhomogeneities. The rings are positioned symmetrically around the bore axis centerpoint. both the position of the magnet coils and the position of the ferromagnetic compensation rings are determined by an iterative optimization process checked by finite element modeling.
