J-TEXT托卡马克上的可见光CCD成像系统

在中型聚变实验装置J-TEXT托卡马克上成功地研制了一套可见光CCD(12harge Coupled Device)成像系统.该系统可沿切向实时观察整个等离子体横截面的可见光辐射图形.该系统的核心器件CCD相机分辨率为659×494,最高帧率110f/s,可按选择捕捉彩色或黑白图片.详细地描述了该成像系统的组成、CCD相机的控制流程以及实际应用的结果.该系统能直观地展现等离子体放电过程,是J-TEXT装置放电运行中必备的重要诊断手段.     

Intermittency of the density fluctuations and its influence on the radial transport in the boundary of J-TEXT

To improve the understanding of the turbulence intermittency,a detailed investigation of the intermittency of the density fluctuations has been performed in the boundary of J-TEXT.The intermittency of the density fluctuations and its influence on the radial transport are reported.The probability distribution functions of the density fluctuations are not scale-invariant,being inconsistent with the self-organized criticality hypothesis.The underlying dynamics of the intermittency are detected using the quiet-time statistical method.The probability distribution function of the quiet times shows double-power-law regions,indicating the existence of correlations between the successive burst events.
