Abstract:

Line shape spectroscopy is a valuable tool both for diagnost ic, and for understanding the basic atomic processes in the boundary region of magnetically confined fusion plasmas. The D_α line profiles are modeled with genet ic algorithm. The modeling profiles are in good agreement with the line profiles obtained in experiment .The results of this analysis suggest that there are one population of hydrogen and three populat ions of deuterium with different temperatures and population ratios.

Key words: Line profile, Genetic algorithm

摘要：

采用遗传算法模拟了D_α 的光谱轮廓, 模拟曲线与实验中观察到的轮廓符合得非常好。分析模拟的结果表明, 在HL- 1M 装置边缘等离子体中, 存在一种H 粒子群和三种D 粒子群, 它们有各自的温度和粒子数比例。
