초록 ▼

A superconductive magnet device comprises a pair of oppositely disposed superconductive bodies in which annular superconductive coils are accommodated, and fine chip-shaped ferromagnetic shims disposed on a surface of the pair of superconductive magnet bodies so as to improve uniformity of magnetic field in a uniform magnetic field in a uniform magnetic field space generated in the proximity of the center between the superconductive magnet bodies, wherein ring-shaped ferromagnetic shims are disposed concentrically with the center of annular superconductive coils on the surface of the superconductive magnet bodies.

1. A superconductive magnet device comprising:a first superconductive magnet body and a second superconductive magnet body, wherein the first and second superconductive magnet bodies have surfaces that are disposed so as to oppose one another; annular superconductive coils disposed within the first and second superconductive magnet bodies; a holding member coupled to at least one of said surfaces of the first and second superconductive magnet bodies, and ring-shaped shims disposed on the holding member. 2. The superconductive magnet device according to claim 1, wherein the ring-shaped shims are disposed along grooves formed on the surface of the holding member.3. The superconductive magnet device according to claim 1, wherein the first and second superconductive magnet bodies respectively include a vacuum adiabatic container and a cryogenic container.4. The superconductive magnet device according to claim 1, wherein the first and second superconductive magnet bodies extend radially so as to be parallel with the holding member.5. The superconductive magnet device according to claim 1, wherein the holding member is coupled to at least one of the first and second superconductive magnet bodies so as to be positioned in an area between the first and the second superconductive magnetic bodies.6. The superconductive magnet device according to claim 1, wherein two holding members are provided such that the first superconductive magnetic body is positioned in an area directly above one of the holding members and the second superconductive magnetic body is positioned in an area directly below the other of the holding members.7. The superconductive magnet device according to claim 1, wherein the holding member contacts the at least one of the surfaces of the first and second superconductive magnet bodies.
