Abstract

The Central Solenoid Model Coil (CSMC) is a critical component of the China Fusion Engineering Test Reactor (CFETR), responsible for generating a peak magnetic field of up to 12 T This is essential for ensuring the proper operation of the fusion reactor's confinement system. To verify the stable operation of the CSMC magnet, a quench stability analysis is conducted on each coil of the CSMC when the peak magnetic field is reached. This paper provides a detailed study of the magnetic field distribution of the CSMC under the operating current of 47 kA. Additionally, the CryoSoft code THEA is used to estimate the minimum quench energy (MQE) and temperature margin for each coil of the CSMC magnet system under electromagnetic disturbances, corresponding to the maximum magnetic field condition. A comparison of the minimum quench energy and temperature margin of the five coils is made, leading to the identification of the most susceptible coil to quench. Additional analyses further reveal that the disturbance length and its axial location along the cooling channel significantly affect local quench sensitivity.

47 kA时CFETR CSMC的淬火稳定性模拟

中央电磁模型线圈（CSMC）是中国聚变工程试验堆（CFETR）的关键部件，负责产生高达12 T的峰值磁场，这对于确保聚变反应堆约束系统的正常运行至关重要。为了验证CSMC磁体的稳定运行，在达到峰值磁场时对CSMC各线圈进行了淬火稳定性分析。本文详细研究了47 kA工作电流下CSMC的磁场分布。此外，利用CryoSoft代码THEA估算了电磁干扰下CSMC磁体系统各线圈的最小猝灭能量（MQE）和温度裕度，对应于最大磁场条件。对五种线圈的最小淬火能量和温度裕度进行了比较，从而确定了最容易淬火的线圈。进一步分析表明，扰动长度及其沿冷却通道的轴向位置显著影响局部淬火灵敏度。
