摘要： In a nuclear magnetic resonance spectrometer, the shape of a detection coil is changed from a conventional cage type to a solenoid type of higher sensitivity. Accordingly, differing from the conventional superconductive magnet of multilayer air core solenoids, a superconductive magnet is right and left divided to split magnets for generating 11 T, preferably, 14.1 T in the horizontal direction, and the magnetic field uniformity is set to 0.001 ppm or less and the temporal stability is set to 0.001 ppm or less.

摘要： A magnet for MRI apparatus has a magnetic circuit which includes a magnetic flux path formed by a ferromagnetic material and a magnetic flux path formed by magnetic flux return coils or magnetic flux control coils, so that a 5-gauss line of leakage fluxes can be kept within a sphere 3 m in radius even when the static magnetic field intensity exceeds 1 tesla and a comparatively light magnet for MRI apparatus can be provided. Further, the fluxes escaping vertically from the static magnetic field sources are led compactly to a horizontal direction by installing magnetic flux paths of ferromagnetic materials and coils with polarities opposing those of the static magnetic fields. This arrangement minimizes an increase in the total height of the magnet for MRI apparatus, keeping the magnet within the total height of 3 m.
