Abstract

Abstract:

The first Nb₃Sn superconducting magnet model coil used in the fusion reactor in China is introduced. We applied a one-dimensional mathematical model (Gandalf) to simulate the superconductor stability of CICC. The relation of stability margin of CICC to magnetic field intensity and operating current is obtained, which is very important to the design and operation of the magnet.

Key words: Cable-in-conduit conductor, Stability, Nb₃Sn, Tokamak

摘要：

介绍了国内首个聚变堆用Nb₃Sn超导磁体模型线圈。采用一维数学模型Gandalf对其管内电缆导体(CICC)结构的超导体稳定性进行仿真，得到了CICC稳定性裕度与磁场强度和运行电流之间的关系。这对于磁体的设计和运行都有十分重要的意义。
