軟性のある高分子化合物テープを使用していた。 This type of superconducting coil is cooled by immersing it in liquid helium, which is a refrigerant, and in order to improve cooling performance, the superconducting conductor 2 is exposed directly to the refrigerant to quickly cool it from room temperature to extremely low temperature, and after cooling, it is energized. It is necessary to promptly remove heat generated by internal turbulence and heat generated by alternating current loss to ensure a stable energized state. The conductor insulation 3 shown in FIG. 2 is intended to obtain the above performance. As the conductor insulation 3, a flexible polymer compound tape was used so that it could be easily wrapped around the superconducting conductor 2.

いという欠点があつた。 However, since conventional superconducting coils were constructed as described above, the conductor insulation 3 is flexible, so the rigidity of the winding as a whole is weak, and the conductor insulation 3 loosens after long-term use, making it difficult to conduct stable current. The drawback was that it was difficult to perform.
