摘要: HL-2M 装置初始放电实验期间采用了一套 8 通道可见光辐射测量系统,4 个通道用于测量 Hα辐射,
其余分别测量 HeⅡ线、CⅢ线、OⅤ线和轫致辐射。该系统采用新型的雪崩放大二极管(APD)模块和光电倍增管
(PMT)模块作为光探测器,这些新型的探测器由于集成度高、供电方式简单而使得整个系统的后端具有体积小、
操作简单及可靠性强等优点。在 HL-2M 装置初始放电期间,该系统为控制运行人员提供了基本的等离子体信息。

Abstract: During the first plasma discharge experiment of HL-2M tokamak, an eight channel visible 
radiation measurement system was used, among which four channels were used to measure Hα, and the rest were 
used for HeⅡ line, CⅢ line, OⅤ line and bremsstrahlung. The system uses new avalanche amplifier diode (APD) 
module and photomultiplier tube (PMT) module as photodetectors. These new photodetectors have the advantages 
of small size, simple operation and high reliability because of their high integration and simple power supply 
mode. During the first plasma discharge activity of HL-2M tokamak, the system provides basic plasma 
information for the control operator. 

Key words: HL-2M tokamak, Plasma, Hα radiation, Impurity radiation
