Abstract

See full text

An open type nuclear magnetic resonance magnet system having an iron ring member. A superconducting coil and a superconducting switch form a closed-loop current circuit to generate a magnetic field. The generated magnetic field gains a magnetic flux circuit and executes magnetic field shielding through upper and lower iron yokes and a lateral iron yoke. The magnet system generates a desired magnetic field in a magnet imaging central area via the superconducting coil. To balance the extremely high electromagnetic force between the superconducting coil and the upper and lower iron yokes, an annular iron ring is mounted in a space defined by an inner perimeter wall of in a cryogenic container. The magnetic field distribution between the superconducting coil and the upper and lower iron yokes is changed via the iron ring, so that the electromagnetic interaction force therebetween is reduced.
