摘要

具有空间和时间分辨的边界旋转诊断（ERD）已在EAST装置上研制完成

经调试已投入EAST实验研究中。多道光纤的观测视线已进行位置标定

经过分析

每道光纤所能耦合的离子辐射通量可表述为解析形式的弦积分量。使用卤素气体标准灯对光谱仪进行了波长标定

并确定了仪器响应函数。ERD可提供边界离子温度和旋转速度

是研究C、O、Li、N、He、Ar等离子在可见光波段辐射的有效工具。通过对CIII谱线的分析

得到了边界离子温度和边界旋转速度的初步实验结果

环向ERD初步实验结果表明ERD测量边界杂质离子温度及旋转速度的可行性。

Abstract

Background: Edge rotation diagnostic system(ERD) with spatial and temporal resolution has been developed on EAST Tokamak.Purpose: The ERD system is an effective method to research the radiation phenomenon of C

He and Ar in visible range.The ERD has been used for the measurement of ion temperature and rotation velocity at the edge plasma.Methods: The measurement was done by using an optical fiber spectrometer and two systems of lenses.Results: The ion radiant flux coupled by each fiber can be expressed as an analytical form

and the sightline of each fiber was determinated

and the spectrometer was calibrated by using a halogen lamp.Conclusions: The initial experimental results were obtained by analysing spectral lines of CIII

which results suggest that ERD has the ability to provide edge ion temperature and rotation velocity.
