中国科学院中国合肥等离子体物理研究所为满足中国聚变工程试验堆中心螺管模型线圈项目的要求，研制了一种短绞距结构的Nb3SnCIC导体。12T磁场和1.5T/S磁场变化是最基本的设计目标。Nb3SnCIC导体的耦合损耗特性是CSMS的关键设计要求，因为交流损耗在磁体中沉积的能量会降低核聚变装置的安全裕度。为了评价Nb3SnCIC导体的耦合损耗性能，在Sultan装置上进行了Nb3SnCIC导体样品的交流损耗测量。本文首先介绍了Nb3SnCIC导体的具体结构设计和交流损耗测试结果。然后，利用多层部分屏蔽模型讨论了耦合损耗特性，并从测量结果中得到了关键的拟合参数。最后，给出了两个典型的现场算例，为CFETR CSMC的安全运行和低温系统的优化提供了Nb3SnCIC导体的耦合损耗能量。
An Nb3Sn cable-in-conduit (CIC) conductor with short twist pitch structure has been developed at Institute of Plasma Physics Chinese Academy of Sciences, Hefei, China, to meet the central solenoid model coil (CSMC) project of China fusion engineering test reactor (CFETR). 12 T magnetic field and 1.5 T/s field change are the most basic design target. The coupling loss characteristics of Nb3Sn CIC conductor is the key design requirement for CSMS because the deposited energy in magnets from ac losses can decrease the safe margin in the nuclear fusion device. In order to evaluate the coupling loss performance of the Nb3Sn CIC conductor, the ac loss measurement for Nb3Sn CIC conductor sample was carried out at SULTAN facility. This paper presents the specific structure design of the Nb3Sn CIC conductor and ac losses test results first. Then, the coupling losses characteristics are discussed with Multizones PArtial Shielding model and the key fit parameters are obtained from measurement results. Finally, two typical field cases are considered to evaluate the coupling loss energy of Nb3Sn CIC conductor for safe operation of the CFETR CSMC and the optimization of the cryogenic system.
