| 摘 要： | 本文叙述用掠入射谱仪在HL-1装置上所做的真空紫外光谱测量。根据杂质谱线的相对强度变化,说明可动石墨孔栏和蒸钛技术对控制等离子体杂质有一定效果。通过分析谱线、软X射线和m=2模式信号扰动之间的关系,指出杂质对等离子体不稳定性的影响。

| Abstract: | The vacuum ultraviolet spectra from the plasma in the HL-1 tokamak were measured using a grazing incidence spectrograph. Judging from the relative intensity changes of the impurity lines, it appears that the techniques of movable graphite limiter, titanium vaporization,etc. are effective for controling the plasma impurity. The influence of the impurity on plasma instability is indicated by analyzing the correlation among signal fluctuations of the lines,soft X-ray and m=2 mode. |
