摘要：

在聚变堆主机关键系统综合研究设施(CRAFT)超导磁体接地检测装置运行过程中，对外界强磁干扰进行屏蔽是保证装置测量可靠性的关键。对检测装置进行静磁屏蔽设计，利用ANSYS 对不同材料、屏蔽厚度、干扰外场等参数对屏蔽效果的影响进行分析。仿真结果表明，贴合在检测装置内表面的5 mm 电工纯铁屏蔽方案空间利用率高，经济效能好，在20~90 mT 静磁场工况下，屏蔽效能在21 dB 以上，屏蔽后的磁感应强度小于10 mT，满足接地检测装置设计运行要求，为超导磁体接地检测装置静磁屏蔽设计提供一定参考。

Abstract:

During the operation of the superconducting magnet ground detection device of the comprehensive research facility for fusion technology (CRAFT), shielding the external strong magnetic interference is the key to ensure the reliability of the device. The magnetostatic shielding design of the detection device is carried out, and the influence of different materials, shielding thickness, interference field and other parameters on the shielding effect is analyzed by ANSYS. The simulation results show that the 5 mm electrician pure iron shielding scheme fitted on the inner surface of the detection device has high space utilization and good economic efficiency. Under the static magnetic field condition of 20~90 mT, the shielding efficiency is above 21 dB, and the magnetic field intensity after shielding is less than 10 mT, which meets the design and operation requirements of the grounding detection device. Some references are provided for the design of magnetostatic shield for ground detection device of superconducting magnet.
