HL-2A装置偏滤器物理分析及其实验的初步证实

Divertor physics analyses and preliminary experimental results on the HL-2A tokamak

采用偏滤器物理分析的"两点"模型,分别计算了HL 2A装置线性状态和高再循环状态的边缘等离子体参数,包括偏滤器靶板的等离子体温度、密度和入射功率,以及上游等离子体温度、密度和平行功率密度的衰减长度。用该模型对线性状态预计的靶板温度和密度与实验结果进行了比较,结果符合较好。

Edge plasma parameters of both linear regime and high recycling regime in the HL-2A tokamak are calculated using the 'two-point' model of divertor physics analyses. They include the plasma temperature, density and incident power on divertor target, and decay lengths of upstream plasma temperature, density and incident power. The target temperature and density predicted with the model of linear regime are in good agreement with experimental results.
