项目摘要

[1] Fundamental experimental work on plasma detachment using TPD-I device.Demonstration of density threshold for plasma detachment in divertor plasma simulator.[2] Research on plasma recombination effects on plasma detachment.Demonstration of plasma recombination in detached plasmas. Continuum and high n spectral intensities show a very cold plasma with the temperature of 0.2-0.3eV in partially local thermodynamic equilibrium. Observation of interesting phenomena associated with molecular activated recombination and the effect of heat pulse.[3] Activities as members of ITER Diverter Expert Group.1) Domestic activity investigation of theory and simulation on edge plasma physics.2) Introduction of activities of ITER Diverter Expert Group on the scientific journal in Japan.[4] Publication of introduction to Detached Plasmas.[5] Activities as a member of International Workshop on Plasma Edge Theory.[6] Collaboration with Massachusetts Institute of Technology on plasma recombination in detached plasma. Structural formation and molecular activated plasma recombinations was deeply discussed with Dr.Krasheninnikov. Comparisons with the experiments in NAGDIS-II have been progressing with the aid of theory group of plasma Fusion Center in MIT.[7] Organization of meeting on "plasma-gas interactions"1) 1,2 November, 1995 at Kashikojima with the attendance of 35 scientists and students.2) 5,6 December, 1996 at Nagoya with the attendance of 30 scientists and students.

[1] 使用 TPD-I 装置进行等离子体分离的基础实验工作。在偏滤器等离子体模拟器中演示等离子体分离的密度阈值。[2]等离子体重组对等离子体分离的影响研究。分离等离子体中等离子体重组的演示。连续谱和高 n 光谱强度显示出非常冷的等离子体，温度为 0.2-0.3eV，处于部分局部热力学平衡。观察与分子激活重组相关的有趣现象和热脉冲的影响。[3]作为ITER Diverter专家组成员的活动。1）国内边缘等离子体物理理论和模拟的活动研究。2）在日本科学期刊上介绍ITER Diverter专家组的活动。[4]发表分离等离子体简介。[5]作为等离子体边缘理论国际研讨会成员的活动。[6]与麻省理工学院合作研究分离等离子体中的等离子体重组。与Krasheninnikov博士深入讨论了结构形成和分子激活等离子体重组。在麻省理工学院等离子融合中心理论小组的帮助下，与NAGDIS-II实验的比较正在取得进展。 [7]组织“等离子体-气体相互作用”会议1) 1995年11月1日2日在贤岛举行，有35名科学家和学生参加。2) 1996年12月5日6日在名古屋举行，有30名科学家和学生参加。
