摘要: 基于 HL-2M 托卡马克初始等离子体放电的工程需求,设计并研制了直流辉光放电清洗系统,包括电
极、馈线、电源、控制以及监测等关键部件和辅助子系统。研制完成后开展了系统装配和工程调试,并投入到首
次等离子体放电。实验结果表明,该直流辉光放电系统运行稳定、可靠,且此辉光放电清洗显著降低了真空室本
底杂质浓度,能满足 HL-2M 装置初始等离子体放电的壁条件需求。

Abstract: Based on the engineering requirements of the first plasma discharge of HL-2M, a DC glow 
discharge cleaning (GDC) system was designed and developed, including electrode, feed through, power supply, 
control and monitoring etc. components and auxiliary sub-system. In addition, the manufactured components are 
assembled, the system engineering commissioning has been completed, and it was implemented for the first 
discharge. The results show that the DC GDC system is stable and reliable, and the GDC cleaning notably reduce 
the main impurities in vacuum chamber. This system can meet the wall condition requirements of HL-2M first 
plasma discharge. 

Key words: Wall conditioning, Glow discharge cleaning system, System engineering development
