Abstract:

A hybrid structure was adopted for the PF coil of the building HL-2M device. In the process of discharge, there is a strong coupling between the coils, each coil will be subjected to a large electromagnetic force. In this paper, PF coil electromagnetic force is computed by the analytic method under the discharge conditions of the largest I_p =3MA plasma current and various configurations. These calculation results are of reference value for the design of PF coil and its support structure.

摘要：

在建的HL-2M装置的PF线圈采用了混合式结构。在放电过程中，线圈之间有很强的电磁耦合，每一个线圈都会受到很大电磁力的作用。采用解析法，在最大I_p=3MA等离子体电流和各种位形的放电条件下，计算分析了PF线圈受到的电磁力。这些计算结果对PF线圈及其支撑结构的设计都是具有参考价值的。
