Abstract—

The phenomenon of improved energy confinement during radiative cooling at the plasma edge was studied experimentally in the T-10 tokamak. It was shown that the effect is independent on the kind of radiating gas. No substantial differences were observed using Ne, which radiates at two-thirds of the plasma radius, or He, which radiates at the very edge. This phenomenon is explained in frames of nonequilibrium thermodynamics. In a self-organized plasma, the energy balance is described by a Smoluchowski-type equation, where the plasma thermal conductivity and its functional dependence on the intensity of the heat flux, perturbing the pressure profile, is determined from experiment.

自组织托卡马克等离子体的能量限制（无运输障碍）

摘要-

在T-10托卡马克中，通过实验研究了在等离子体边缘辐射冷却过程中改善的能量限制现象。结果表明，该效果与辐射气体的种类无关。使用在等离子半径的三分之二处辐射的Ne或在最边缘处辐射的He时，没有观察到实质性差异。这种现象在非平衡热力学框架中得到了解释。在自组织等离子体中，能量平衡由Smoluchowski型方程式描述，其中等离子体热导率及其对热通量强度的函数依赖性（扰动压力分布）由实验确定。
