在未来的聚变堆设计中，可拆卸超导磁体的开发将成为重要的技术问题之一，它将为降低反应堆建造和维护成本带来巨大的效益。然而，在常规设计中，存在在接头处产生热的致命问题，这导致磁体的淬火。另一方面，具有大比热的高温超导体现在被用于磁体。在以前的研究[国际应用电磁学和力学杂志，IOS出版社，出版中。第12届国际等离子体物理和受控核聚变会议和亚洲等离子体聚变协会第三届科学大会联合会议，东京。2001年，在出版中]，HTcS. C.已提出了胶带，据报道其接触性能相对优异。因此，在这项研究中，在磁带中的电流分布计算通过数值分析，然后在接合区域的发热估计，以评估在一些接合情况下的接触性能的差异。结果表明，接触性能不依赖于各S.C.细丝。
For future design of fusion reactors, development of the remountable superconducting magnet can become one of the important technical issues, which will bring huge benefit to reduce both costs of reactor construction and maintenance. In the conventional design, however, there is a fatal problem of heat generation occurring at the joints, which causes quenching of the magnet. On the other hand HTcsuperconductors, which has large specific heat, are now being used for magnets. In the previous research [International Journal of Applied Electromagnetics and Mechanics, IOS Press, in press. Joint Conference of the 12th International Toki Conference on Plasma Physics and Controlled Nuclear Fusion and The Third General Scientific Assembly of Asia Plasma Fusion Association, Toki. 2001, in press], the butt jointing method of HTcS.C. tapes had been proposed and its contact performance had been reported to be relatively excellent. In this research, therefore, the current distributions in the tape are calculated by numerical analysis and then the heat generations in the jointing region are estimated to evaluate the difference of contact performance in some jointing cases. The results show that the contact performance does not dependent on relative location of each S.C. filaments.
