  • Magnetic field homogeneity correction for superconducting magnet
    Patent number: 5900792
    Abstract: Magnetic field homogeneity correction system including coils for a superconducting magnet assembly are wound on the same coil forms as the axially spaced main magnet coils such that they are superimposed radially to simplify the system including design requirements for associated passive shimming and reduce transverse magnetic forces therebetween, and improve magnetic field homogeneity.
