(57) [Summary] [PROBLEMS] To reduce the size of the entire superconducting coil device, simplify its manufacture, and further reduce the consumption of liquid helium. SOLUTION: The axis of a refrigerator 7 is vertical, and a vacuum vessel 2 A heat exchanger main body 6a attached to one side and miniaturized and connected to a refrigerator head 8a was provided in the liquid helium 2. Further, the superconducting coils 1a and 1b are configured to be in contact with the outside of the helium container 3 to simplify the production. |
