本文通过定义一个唯一的标量参数轮廓增益因子，提出了一种新的内输运势垒（ITB）形成判据。的轮廓增益因子示出的限制相对于任意的参考温度分布在L模式的改善程度。作为大螺旋装置（LHD）的参考L模式轮廓，通过L模式轮廓函数将边缘离子温度轮廓数据外推到核心，该L模式轮廓函数的特征在于热扩散系数与局部离子温度成正比。轮廓增益因子被定义为实验测量的离子存储能量与从参考L模式轮廓评估的离子存储能量的比率。所提出的方法应用于LHD的实验数据，并证明其量化的ITB强度的能力。
In this paper, a new criterion for the internal transport barrier (ITB) formation is proposed by defining a unique scalar parameter, the profile gain factor. The profile gain factor shows degree of the confinement improvement with respect to an arbitrary reference temperature profile in the L-mode. As the reference L-mode profile for the large helical device (LHD), the edge ion temperature profile data is extrapolated to the core by the L-mode profile function, which is characterized by the thermal diffusion coefficient being proportional to the local ion temperature. The profile gain factor is defined as the ratio of the ion stored energy experimentally measured to that evaluated from the reference L-mode profile. The proposed method is applied to the LHD experimental data, and its capability for quantification of the ITB strength is demonstrated.
