为了建立小型100 kWh超导磁储能装置所需的技术，制作了一个超导磁储能模型线圈。1996年在日本原子能研究所进行了性能测试。之后，该线圈被安装在劳伦斯利弗莫尔国家实验室（LLNL）的设施中，并于1998年在日本和美国的合作下进行了测试。LLNL的交流损耗结果与JAERI的结果一致。结果再次证实了线圈的耦合损耗由短时间常数和长时间常数两部分组成。从霍尔探针的信号中我们发现，CIC导体中产生了具有长衰减时间常数的电流环。这些回路可以增强线圈中的附加AC损耗。为了减少交流损耗，我们制作了具有CuNi表面的小尺寸CIC导体股线，并制作了小线圈。测量的小线圈的交流损耗减小到约1/6。股线上的CuNi表面被证明是有效的，以减少线圈中的交流损耗。
In order to establish a technology needed for a small-scale 100kWh SMES device, a SMES model coil was fabricated. Performance tests were carried out at the Japan Atomic Energy Research Institute (JAERI) in 1996. After that, the coil was installed in facilities of the Lawrence Livermore National Laboratory (LLNL) and tested in 1998, in collaboration between Japan and the United States. The AC loss results at LLNL were in good agreement with those at JAERI. It was reconfirmed from the results that the coupling loss of the coil consists of two components with short and long time constants. We found out from the signals of Hall probes that the current loops with long decay time constants were induced in the CIC conductor. These loops could enhance additional AC loss in the coil. To reduce the AC loss, we made small-sized CIC conductor of strands having a CuNi surface, a fabricated the small coil. The measured AC loss of the small coil was reduced to about 1/6. The CuNi surface on the strands was demonstrated to be effective to reduce AC loss in the coil.
