摘要： PROBLEM TO BE SOLVED: To modify a magnet device so that disturbance behavior of a magnet device is corrected to be optimum taking diamagnetism of a superconductor into consideration by a simplest means. SOLUTION: In a superconducting magnet device, magnetic field in the z direction in a working volume produced by these additional current paths during operation and due to induced currents does not exceed a magnitude of 0.1 Tesla. The magnet coil and the current path are designed so that a value β (mathematical expression X) is different larger than 0.1 from a value β0 (mathematical expression Y) which is to be obtained when α=0 when an additional disturbance coil generates a substantially homogeneous disturbance field in the magnet volume. As a result, it is possible to modify a conventional magnet device to optimize disturbance behavior of a magnet device by a simple means taking diamagnetism of a superconductor into consideration.

摘要： PROBLEM TO BE SOLVED: To provide a magnet device with an additional magnetic field generation coil system, wherein a current is supplied from an external power supply for generating magnetic field inside a working volume which is not substantially 0, and its design method. SOLUTION: The magnet device generates a magnetic field in the direction of a z axis in a working volume disposed around z=0. It has a superconducting magnet coil system M with at least one energizing coil, an additional magnetic filed generating coil D where a current is supplied from an external power supply and which generates a magnetic field which is not substantially 0 in a working volume, and optionally another superconducting closed current path (P1,..., Pn). In the device, a magnetic filed in the direction of a z axis is generated in operation by a current induced thereby in an operation volume, and a magnetic field of the additional magnetic field generation coil D does not exceed 0.1 Tesla. In the magnet device, it is possible to improve the device to maximize effective magnetic field efficiency of the additional magnetic field generation coil system D to the conventional superconducting magnet coil by taking diamagnetic characteristics of a superconductor inside the superconducting magnet coil M into consideration.
