摘要
中国聚变工程试验堆（CFETR）中心螺管模型线圈，内部磁体为Nb3Sn线圈，外部磁体为NbTi线圈。模型线圈最高磁场可以达到12．0T。针对提出的内部线圈方案，借助一维失超分析软件Gandalf，对Nb3Sn线圈的温度裕度、稳定裕度做了计算。在49kA，12T运行条件下，温度裕度为1．9K，稳定性裕度421．2mJ／cm^3～426．6mJ／cm^3。结果表明，温度裕度和稳定性裕度均不低于ITER导体设计要求。
The Nb3 Sn as inner coils and NbTi as outer coils were adopted for central solenoid model of China Fusion Engineering Test Reactor （CFETR）. In this paper, the authors calculated the temperature margin and the stability margin of the inner coils by 1 D quench analysis code - Gandalf. Under the 49kA, 12T operating conditions, the Nb3 Sn coils had a temperature margin of 1.9K, and stability margin of 421.2mJ/cm3 - 426.6mJ/cm3. The results show that the temperature margin and stability margin are not lower than the design requirements of ITER conductor.
