題があった。With the above conventional technology, it is difficult to obtain a highly reliable and inexpensive superconducting device. That is, since it is necessary to surround the superconducting member in a high vacuum environment space, many vacuum leak tests have to be performed during the process of manufacturing the superconducting device. In addition, thermal strain caused by cooling and strain caused by electromagnetic force cause minute leaks, which impede the normal operation of the superconducting device.

ってもよい。The above objectives are achieved by using superconducting materials that operate at relatively high temperatures (e.g. liquid nitrogen temperatures) and by employing adiabatic techniques that do not require a high degree of vacuum. Namely, the present invention provides a member using a superconducting material, a means for cooling the member (for example, liquid nitrogen or a refrigerator), a first heat insulator supporting the member, and a second heat insulator surrounding the member. It is characterized by the use of powder insulation material placed in a vacuum environment. Here, it is preferable to use a mixture of pearlite powder and strips of aluminum-deposited polyester foil as the powder insulation material, and as the second insulation material, a plurality of insulating materials with built-in insulation material placed in a vacuum environment are preferable. Furthermore, a plurality of porous heat insulating materials may be used as the second heat insulating material, and the outside may be covered with a thermally conductive metal body.

Porous insulation materials are used at atmospheric pressure, so they are somewhat thermally conductive. There is a risk that dew may adhere to the outer surface. Condensation is prevented by covering the outside with a metal body equipped with radiation fins and heat pipes.
