The aim of this research program is to clarify physics of helical plasmas through various international magnetic configuration experiments, and explore the prospect of steady-state fusion reactor by making a progress on advanced researches. There are a variety of magnetic configurations in helical systems. Therefore, it is a key to identify the magnetic configuration and its control for the wide research of plasma characteristics. Until now, there is an international network on magnetic configuration, MHD equilibrium, stability and transport of helical plasmas as a part of the LHD International Mutual Experiment Program (LIME). In this research program, the three research items; (1) steady-state concept and diagnostics development, (2) internal structure and transport analysis, (3) external control and new magnetic configuration development, are adopted and the following results are obtained.(1) The helical magnetic configuration is characterized by the steady-state, and the diagnostic … More s development experiments have been done using high-temperature super-conducting coils. In addition, the diamagnetic measurement experiment by the usage of helical coil current and voltage, and the finite-beta plasma equilibrium analysis clarify the demonstration of new method of plasma energy measurement.(2) By the detailed 3-dimentional plasma equilibrium-transport analysis, the international collaboration on database analysis, impurity analysis and anomalous transport has been done, and the bench-mark test of integrated analysis codes and the new transport physics properties are clarified.(3) For exploring advanced magnetic configuration, a new N=1 compact quasi-symmetric configuration and a simplified spherical tokamak-stellarator hybrid have been proposed, and some preliminary plasma experiments are carried out. These optimization research analyses are done by the collaboration with Russian and Swiss research group.Based on the new results of the 6-year research program, the confinement control research using new and original magnetic configuration is expanding now.

本研究计划的目的是通过各种国际磁构型实验阐明螺旋等离子体的物理性质，并通过取得先进研究的进展来探索稳态聚变堆的前景。螺旋系统中有多种磁性构型。因此，识别等离子体的磁构型及其控制是深入研究等离子体特性的关键。到目前为止，作为LHD国际相互实验计划(LIME)的一部分，有一个关于螺旋等离子体的磁组态、MHD平衡、稳定性和输运的国际网络。在本研究方案中，采用了三个研究项目：(1)稳态概念和诊断的发展，(2)内部结构和输运分析，(3)外部控制和新的磁构型的发展，得到了以下结果：(1)螺旋磁构型的稳态特征和诊断…S利用高温超导线圈进行了更多的开发实验。通过详细的三维等离子体平衡输运分析，完成了数据库分析、杂质分析和反常输运等方面的国际合作，阐明了综合分析程序的标尺检验和新的输运物理性质。(3)为了探索先进的磁构型，提出了一种新的N=1紧凑准对称构型和简化的球形托卡马克-星体混合体，并进行了初步的等离子体实验。这些优化研究分析是通过与俄罗斯和瑞士研究小组的合作进行的。基于6年研究计划的新成果，使用新的和原始的磁构型的约束控制研究正在扩大。较少
