PROBLEM TO BE SOLVED: To prevent an accident from being caused by a method wherein the magnetic coupling between a water-cooled magnet and a superconducting magnet is made small by arranging a conductor, with which one turn is formed in the space between the water-cooled magnet and the superconducting magnet, is arranged on the concentric circle with each magnet. SOLUTION: The conductor 12 such as a coil, etc., with which one turn is formed, is arranged on the concentric circle with magnetic bodies 1 and 3 in the space between a water-cooling magnet body 1 and a superconducting magnet main body 3. As a result, the magnetic coupling between the water- cooling magnet body 1 and the superconducting magnet main body 3 can be made small. To be more precise, the mutual influence of magnetic behavior can be made small. Accordingly the accident caused by the dielectric breakdown of coil by an excessive current can be prevented actively and completely. |
