Abstract

Near-zero magnetic environment serves as a fundamental research condition for multiple scientific fields. To obtain a large-scale and high-performance near-zero magnetic environment, this article presents a coil design method based on the boundary element method (BEM) for compensating the nonuniform static magnetic field existing in the magnetic shielding room (MSR). To achieve precise compensation of nonuniform magnetic field, BEM-based image method is introduced to eliminate the deviation by coupling between the magnetic field generated by the coil and the magnetic shielding material, and the gray wolf optimization (GWO) algorithm is employed for the optimal design of coils. The experimental results show that the coils designed by the method of this article can effectively compensate the nonuniform magnetic field distribution within a

$100\times 100\times 100$

mm central area of the MSR. The range of the residual magnetic field has been reduced by 87.8%, thereby establishing an environment below 1 nT in the central area of the MSR. The proposed method will lay the foundation for the research of high-performance nonuniform magnetic compensation coils within the MSR.

磁屏蔽室非均匀静磁补偿线圈的设计

近零磁环境是多个科学领域的基础研究条件。为了获得大尺度、高性能的近零磁场环境，提出了一种基于边界元法的线圈设计方法来补偿磁屏蔽室（MSR）中存在的非均匀静磁场。为了实现对非均匀磁场的精确补偿，引入基于边界元法的图像法，利用线圈产生的磁场与磁屏蔽材料之间的耦合消除偏差，并采用灰狼优化算法对线圈进行优化设计。实验结果表明，采用本文方法设计的线圈可以有效地补偿MSR中心100 × 100 × 100 × 100 mm区域内的不均匀磁场分布。残余磁场的范围减小了87.8%，从而在MSR中心区域建立了1 nT以下的环境。该方法为研制高性能非均匀磁补偿线圈奠定了基础。
