探讨了一种在磁屏蔽室内套装三轴亥姆霍兹线圈系统的复合装置。该装置可以在周边磁场较乱、磁场梯度较大的环境中构建一个大区域、高均匀度的弱磁场空间,拓宽了弱磁空间的应用领域,降低了构建成本和构建难度。给出了该装置构建的5个技术环节要点。
A composite device of three-axis Helmholtz coil system in magnetic shielding room is discussed. The device can build a large area and high uniform field of weak magnetic field in the circumstance that the surrounding magnetic field is more chaotic and the magnetic field gradient is larger, widening the application field of the weak magnetic space, reducing the construction cost and the difficulty of construction. The key points of the five technical aspects of the device construction are given.
