PROBLEM TO BE SOLVED: To provide a cusp magnetic field generating superconducting magnet device for generating a cups magnetic field distribution without making the diameter of a superconducting coil large. SOLUTION: The device is equipped with a vacuum container 70 in a double-cyclinder structure having a hollow space whose center axis is perpendicular, two couples of superconducting coils 11a and 11b, and 21a and 21b which are arranged in the vacuum container so that their center axes are horizontal, and a refrigerator for cooling those superconducting coils. The two couples of superconducting coils face each other across the hollow space and surround the center axis of the hollow space, and symmetrical surfaces of each couple of superconducting coils contains the center axis. Further, mutually adjacent superconducting coils are electrified so that magnetic fields generated by the superconducting coils are in opposite directions. COPYRIGHT: (C)2004,JPO |
