托卡马克边缘等离子体谱线形状模拟和离子温度起伏

Spectral line shape modeling and ion temperature fluctuations in tokamak edge plasmas

Y. Marandet, J. W. Dufty

摘要:

在这项工作中,我们使用一个被动平流模型的离子温度波动,以调查他们对多普勒谱线形状的影响。在Braginskii方程的框架中讨论了模型的相关性,随后的概率密度函数评价依赖于在中性流体中获得的结果。所得到的多普勒线轮廓显示出特征指数尾巴。

英文摘要:

In this work, we use a passive advection model for ion temperature fluctuations, in order to investigate their effects on Doppler Spectral line shapes. The relevance of the model is discussed in the framework of the Braginskii equations, and the subsequent Probability Density Function evaluation relies on results obtained in neutral fluids. The resulting Doppler line profiles are shown to exhibit characteristic exponential tails.
