用自行研制的X射线弯晶谱仪首次在HL-1托卡马克装置上进行了安装调试和谱获取实验。谱仪是具有时间分辨的高集光本领、高分辨Johann型布喇格晶体谱仪,它采用了有效面积为11×5cm~2,曲率半径为377cm的大石英晶体板作为色散部件,探测器是一维空间分辨的大尺寸(10×10cm~2)多丝正比计数器,谱分辨率≈18000。在有氩注入的氢等离子体放电情况下,用这台谱仪获取了部分波段的类HeAr离子伴线谱,并由类HeArⅩⅦ3.9457A共振线的多普勒展宽,初步给出了中心离子温度T_i(0),表明谱仪研制获得成功。对实验结果进行了讨论,并提出谱仪的改进意见。
For the first time, the installation, commissioning and spectrum acquisition experiments were carried out on a HL-1 tokamak device by using a self-developed X-ray crystal bending spectrometer. Spectrometer is a time-resolved high concentration of light, high resolution Johann Bragg crystal spectrometer, which uses an effective area of 11 × 5cm ~ 2, the curvature radius of 377cm large quartz crystal plate as a dispersion component, the detector is a Dimensional resolution of large-size (10 × 10cm ~ 2) multi-wire proportional counter, spectral resolution ≈ 18000. In the case of hydrogen plasma discharge with argon injection, some of the band-like HeAr ions were obtained by this spectrometer. The Doppler broadening of the resonance line like HeArXVII3.9457A was also used to give the central ion temperature T_i (0), indicating that the successful development of spectrometer. The experimental results are discussed, and the improvement of spectrometer is proposed.
