Superconducting magnet apparatus using superconducting multilayer composite member, method of magnetizing the same and magnetic resonance imaging system employing the same

摘要

A superconducting magnet apparatus which includes a cryostat vessel for containing therein a coolant for realizing superconductivity, a magnetic flux generating unit disposed within the cryostat vessel and including a superconducting multilayer composite member constituting a sustaining medium for a persistent current which generates a magnetic flux along a center axis of a predetermined magnetic field space, and members holding the magnetic field generating unit within the cryostat vessel.
