| 摘 要： | 离子温度是托卡马克等离子体一个重要参数，介绍了一套振镜扫描装置，该装置主要由0.5m单色仪和安装在出射狭缝前的振动的石英镜片组成，时间分辨率小于10ms，系统测量误差小于20eV。测量了HT-6M托卡马克CV(227.1nm)谱线的线形，并由谱线的多普勒展宽得出欧姆加热和离子回旋共振加热（ICRH）下的离子温度，结果表明ICRH期间离子温度由200eV升高到300eV。这套装置广泛应用在中小型托卡马克上。

| Abstract: | The ion temperature in Tokamak plamsa is an important parameter. A vibration mirror instrument for measurement of plasma ion temperature was established, and this system consists of a 0.5m Czerny-Turner spectrometer and a vibration quartz mirror in front of the exit slit of the spectrometer. The CV (227.1nm) line shape was measured by vibrating the mirror, which was controlled by a scan controller, the time dispersion of the system is less than 10ms and the error is less than 20eV.The ion temperature in HT-6M Tokamak was derived from the Doppler broaden of CV line during OMH and ICRH. The result shows that the ion temperature rises from 200eV to 300eV during ICRH. The equipment can be widely applied to small and medium sized Tokamak. |
