In this study, a method to design highly uniform magnetic field cylinder coils based on the grey wolf optimizer (GWO) algorithm is proposed. For the first time, this method is applied to the magnetic field design area. In this way, the uniform magnetic field region was expended, and the newly designed coils could be utilized in atomic sensors. Compared with other types of coil, namely the Genetic Algorithm (GA) coils and Lee–Whiting coils, the GWO coils exhibit the highest degree of uniformity. The uniform region of the GWO coils is in the range of [−0.53R, 0.53R] along the z-axis and exhibits a relative uniformity of less than 0.1%, as confirmed by experiments. This indicates that the newly designed coils display a huge superiority in the size of the uniform region, thus being able to provide a more uniform magnetic field. With the aim of enhancing the performance of the magnetic field compensation system of SERF atomic sensors, the proposed method also serves as an effective optimized algorithm to design highly uniform magnetic field coils coupled with magnetic shielding layers.

原子传感器中基于灰狼优化算法的高均匀磁场圆筒线圈设计


本研究提出了一种基于灰狼优化器（GWO）算法的高度均匀磁场圆柱线圈的设计方法。该方法首次应用于磁场设计领域。这样，均匀磁场区域就扩大了，新设计的线圈可以用于原子传感器。与其他类型的线圈（即遗传算法 (GA) 线圈和 Lee-Whiting 线圈）相比，GWO 线圈表现出最高程度的均匀性。实验证实，GWO线圈的均匀区域沿z轴在[-0.53R，0.53R]范围内，并且表现出小于0.1%的相对均匀性。这表明新设计的线圈在均匀区域的尺寸方面表现出巨大的优势，从而能够提供更均匀的磁场。为了提高SERF原子传感器磁场补偿系统的性能，该方法也可作为设计与磁屏蔽层耦合的高度均匀磁场线圈的有效优化算法。
