随着磁约束聚变研究的发展，对磁场的要求越来越高。在高场磁体中常用的Nb3Sn超导体，没有太大的改进潜力。我们需要用新的超导材料来发展导体。Bi2Sr2CaCu2Ox就是这样一种很有前途的材料。ASIPP设计和制造了一种42线的亚尺寸导体，并在特温特大学的横向磁场标准磁化磁体上测试了其交流损耗。使用现象学模型对测试结果进行分析。结果表明，在相同条件下，Bi2212导体的耦合损耗大于Nb3Sn导体。这可能是由于Bi2212使用的银基比Nb3Sn基的铜基的电阻小。
With the development of magnetic confinement fusion research, more and more stronger magnetic fields are needed. Commonly used superconductor of Nb3Sn in high-field magnets which does not have much potential for improvement. We need to develop conductor with new superconducting materials. Bi2Sr2CaCu2Ox is such a promising material. One sub-size conductor with 42 wires was designed and manufactured at ASIPP and its AC loss has been tested in the standard magnetization magnet for transverse magnetic fields at the University of Twente. The phenomenological model was used to analyze the test results. The results show that the coupling loss of Bi2212 conductor is larger than that of Nb3Sn conductor under the same condition. This may due to the fact that the Bi2212 strands use the silver matrix which resistance is less than that of the Nb3Sn strand’s copper matrix.
