摘要:

研究了线圈的有限尺寸效应对工程及磁场位形特性的影响,如面扭转、线扭转、曲率、电磁力,以及磁拓扑结构。通过改变线圈截面的形状,设计了多套无面扭转的三维线圈系统,并对这些线圈系统进行了综合研究与分析,提出一种新的对于有限尺寸线圈系统的优化方法。与原有线圈设计相比,利用该方法优化后的线圈系统,具有更低的电磁力和优化的线圈构形,并可以精确产生约束等离子体的三维目标磁场位形。

Abstract:

The influences of the finite-sized effects of coils on various engineering and magnetic field configuration characteristics, such as surface twist, line torsion, curvature, electromagnetic force and magnetic topology, are studied. A number of surface-twist-free three-dimensional (3D) coil systems have been designed by changing the coil configuration. By analyzing and studying the coil systems, a new optimized method for finite-size coil system is achieved. Compared to the original coil design, the new coil system possesses much lower electromagnetic forces and optimized shapes, which can produce the 3D objective magnetic field configuration to confine the plasma precisely.

Key words: Coil, Electromagnetic force, Coil optimization
