摘要/Abstract

摘要： 采用偏滤器物理分析的/两点0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。

关键词: 偏滤器物理, /两点0模型, 线性状态, 高再循环状态

Abstract: Edge plasma parameters of both linearregime and high recyclingregime in theHL-2Atokamak are calcu- lated using the/two-point0model of divertor physics analyses. They include the plasma temperature, density and inc-i dent power on divertor target, and decay lengths of upstreamplasma temperature, density and incident power. The target temperature and density predicted with the model of linear regime are in good agreementwith experimental results.

Key words: Divertor physics;/Two-point0model, Linear regime, High recycling regime
