Abstract

For the magnetic field analysis or design, it is important to know the behavior of the magnetic field in an interesting space. Magnetic field mapping becomes a useful tool for the study of magnetic field. In this paper, a numerical way for mapping the magnetic field within the cylindrical center volume of magnet is presented, based on the solution of the Laplace’s equation in the cylindrical coordinate system. The expression of the magnetic field can be obtained by the magnetic flux density, which measured in the mapped volume. According to the form of the expression, the measurement points are arranged with the parallel cylindrical line (PCL) method. As example, the magnetic flux density generated by an electron cyclotron resonance ion source (ECRIS) magnet and a quadrupole magnet were mapped using the PCL method, respectively. The mapping results show the PCL arrangement method is feasible and convenience to map the magnetic field within a cylindrical center volume generated by the general magnet.

通用磁体圆柱形中心体内磁场映射的研究

对于磁场的分析或设计，了解磁场在一个感兴趣的空间中的行为是很重要的。磁场成图是研究磁场的一种有效工具。本文在圆柱坐标系下求解拉普拉斯方程的基础上，提出了磁体圆柱形中心体积内磁场的数值映射方法。磁场的表达式可以通过在映射体中测量的磁通量密度得到。根据表达式的形式，采用平行圆柱线(PCL)法布置测点。以电子回旋共振离子源(ECRIS)磁体和四极磁体为例，分别用PCL方法绘制磁通量密度图。结果表明，用PCL排列法对普通磁体产生的圆柱形中心体内的磁场进行映射是可行的，方便的。
