论文摘要
具有六个具有六个具有嵌入式VacoFlux-50的电磁体的多旋风线孔（MPD），已运行，具有实验性控制无磁场区域的能力，磁场的径向剖面，以及通过更换磁场电流来控制磁场的径向轮廓。为了验证3-D几何形状中多偶极线尖磁场（MMF）配置，使用COMSOL软件进行了有限元仿真。本文介绍了在1.2m长度和直径40厘米的腔室下进行的3-D磁场模拟结果。模拟结果与实验测量的磁场曲线显示出良好的一致性。执行的磁场仿真结果清楚地捕获了该配置对空区域（几乎没有场区）的完全控制，还能够改变磁场的磁场值和径向变化。此外，已经讨论了设备末端横截面上的磁场曲线。
A Multi-dipole line cusp configured Plasma Device (MPD) having six electromagnets with embedded Vacoflux-50 as a core material has been operated with a capability to experimentally control the field-free region, the radial profile of magnetic field, and pole magnetic field by changing magnet current. For the validation of multi-dipole line cusp magnetic field (MMF) configuration in a 3-D geometry, a finite element simulation has been performed using COMSOL software. This paper presents 3-D magnetic field simulation results of multi-pole line cusp magnetic field configuration performed over the 1.2m length and 40cm diameter chamber in the vacuum condition. The simulation results show good agreement with the experimentally measured magnetic field profile. The performed magnetic field simulation results clearly capture that this configuration has full control over a null region (nearly field-free region) as well is capable to change the magnetic field values and radial variation of the magnetic field. Moreover, the magnetic field profiles over the end cross-section of the device have been discussed.
