器５も大きくならざるを得ない。Superconducting coils are normally used after being cooled to a cryogenic temperature of about 4 K, and at this time, electromagnetic force acts on the superconducting coils as well as its own weight. Therefore, a support device for a superconducting coil is required to have an appropriate design to take into account the conflicting factors of reducing thermal conduction and intrusion heat as much as possible and supporting the above-mentioned external force. Fourth
The drawing shows an example of a conventional design. In this case, a superconducting coil (including a helium container, hereinafter omitted) 1 is provided with support legs 4 having a cross-sectional area large enough to withstand external forces, and However, in order to suppress the amount of heat intrusion to a predetermined level, the conduction length t of the supporting legs 4 is made to be long, so the vacuum container 5 also has to be large. I don't get it.
本発明は、このような事情に鑑みて提案されたもので、

ものとすることができる。In the device of this invention, the magnetic field generated during coil excitation is compressed by its diamagnetic property in the gap between the superconducting coil and the superconducting support in a superconducting state, and the repulsive force generated there is balanced with the external force acting on the superconducting coil. do. Therefore, since the superconducting coil does not touch the superconducting support in a floating state, the conductive heat penetration becomes zero, and the support legs only need to have a cross-sectional area that can ensure support strength, and should be short in length. Can be done.

When a current ■ is applied to the superconducting coil 1, magnetic lines of force 6 are generated around the coil as shown in the figure, and the superconductor in the superconducting state Due to the diamagnetic property of the body 2, the average magnetic flux density becomes B in the gap between the two.
