PROBLEM TO BE SOLVED: To provide a split pair superconductor magnet device which can be lessened in manufacturing cost and in which an entrance hole 12 through which a beam such as a neutron beam impinges is bored at an optional position. SOLUTION: A split pair superconductive magnet device has such a structure in which superconductive coils C and C' are arranged in a double-decked way in a cryostat 1, concentric rings and spacers are provided between the coils C and C' to form a gap G, and a beam B such as neutron beam or the like is made to penetrate through the gap G, where the concentric rings and spacers have such structures in which both edges of C-shaped rings 101, 102, etc., are made to bear against both sides of fan-shaped spacers 11. |
