| 摘 要： | 本文叙述在HL-1装置上做的真空紫外区(300-2000A)光谱实验。用微通道板象增强器摄出了等离子体光谱,对光谱进行了辨认和分析;采用光电法测量了谱线随时间的变化和改变孔栏半径时杂质的变化情况,观察了等离子体发生小破裂时出现的光谱现象,对杂质的来源及某些性质作了分析研究;使用两条CⅣ谱线强度比,测出了放电初期的电子温度。

| Abstract: | Measurements on vacuum ultraviolet spectra(300-2000A)from the plasma in HL-1 tokamak are described.The majority of plasma spectra recorded by a microchannel plate(MCP) image intensifier have been identified.The plasma spectra behavior,source of impurities,spectral phenomena caused by small disruptions,and variation of impurity content due to change in limiter radius are discussed.Electron temperature at the initial stage of discharge is determined by measuring the relative intensities of lines emitted from the same element at same ionization states |

| Keywords: | Spectra MCP image intensifier Impurity Electron temperature measurement |
