摘要:

通过采用控制变量法,调整引线外弧段半径、回线内外弧段半径及回线与TFC间隙等参数,使HL-2M装置的TFC馈线系统在等离子体区域产生的最大杂散磁场降为3.69×10-4T,同时初步评估了馈线在一次放电后的绝热温升,为馈线是否需要冷却提供依据。最后在优化馈线位形参数后,对馈线的支撑和连接形式进行了初步的定性分析和讨论。

Abstract:

Optimization of the stray magnetic field in the plasma area induced by the feeder system of toroidal field coils (TFC) for HL-2M tokamak is presented. By adjusting the structural parameters of TFC feeder, such as the outer arc radius of the lead bus, the inner and outer arc radius of the return bus and the gap between return bus and TFC, etc., the stray field in the plasma area is minimized, and the maximum field is 3.69×10-4T. The maximum temperature rise in the feeder after one shot is estimated, the results show that the feeder doesn’t need to be cooled actively Based on the optimized parameters, the mechanical structure of the feeder and its support, such as the size, connector, flexible feeders, etc., are preliminarily analyzed.

Key words: HL-2M tokamak, Feeder system of TFC, Stray magnetic field
