摘要:

根据HL-2M装置5MW-NBI加热束线总体设计参数、注入器的部件空间布局、几何汇聚特点等,建立了基于8饼线圈的注入器偏转磁体3D模型。利用电磁场模拟软件CST Studio详细模拟了注入器的偏转磁体产生的偏转磁场分布,不同成份离子束的偏转轨迹。在模拟分析结果的基础上优化了偏转磁体的物理结构,完成了磁体的工程设计、加工和测试。偏转磁体的磁场测试结果表明,测试值与CST计算值的偏差小于±5%,达到注入器偏转磁体设计要求。

Abstract:

According to the design parameters of 5MW-NBI beam line of HL-2M tokamak, spatial arrangement of components, geometrical focus characters and so on, 3D model of the deflecting magnet with 8 groups of wires is built up. With an electromagnetic field simulation software-CST Studio, the deflection magnetic field distribution and deflection trajectories of ion beams with different components are obtained. With the simulation results the physical structure of deflecting magnet is optimized, the engineering design of the magnet is completed and then the manufacture and test are finished. The testing result of the magnetic field distribution of the deflecting magnet shows: the error between measurement value and calculation result is less than ±5%, and the machined deflecting magnet can meet the design requirement.

Key words: HL-2M tokamak, NBI beam line, Deflecting magnet, Ion beam dump
