项目摘要

In order to realize future fusion reactors, helical plasma confinement system is considered as an influential alternative to the Tokamak systems. The Large Helical Device(LHD) in National Institute for Fusion Science, Japan is a leading machine among helical systems. In Germany a same-sized helical device having different magnetic configuration is under construction. It is very important to collaborate with each other. The main objective of this research is to establish transport database between Japan, Germany and Spain for clarifying confinement mechanism in helical plasmas, and to promote international collaboration experiments under IEA Stellarator Implementing Agreement.Within 3-year term of this scientific research project, the following useful research collaborations have been performed.(1)Project planning and research investigation : Several researchers visited Europe and attended the IEA International Executive Stellarator Meeting for promoting the LHD International Mutual Experiment (LIME) program for high-performance and steady-state sustainment of helical plasmas.(2)Personal exchange for research collaboration : To present the results of this grant-in-aid research, a few scientists have been abroad and attended the International Conference, and discussed with foreign scientists. Especially the differences in plasma confinement, transport code development and future collaboration plans were discussed.(3)Invitation of foreign scientists related to confinement, diagnostics and reactor : Within the framework of this research, several foreign scientists from Germany, Swiss, USA, Russia and so on were invited, and a variety of collaboration researches on plasma confinement, diagnostics and reactor design were carried out, which promoted the LIME program.These research collaborations are highly evaluated in the international executive committee under International Energy Agency (IEA) Stellarator Implement Agreement.

为了实现未来的聚变反应堆，螺旋等离子体约束系统被认为是托卡马克系统的一个有影响力的替代方案。日本核聚变科学研究所的大型螺旋装置是螺旋系统中的一种先进装置。在德国，具有不同磁结构的相同尺寸的螺旋装置正在建造中。彼此合作是非常重要的。本研究的主要目的是建立日本、德国和西班牙之间的输运数据库，以阐明螺旋等离子体中的约束机制，并促进IEA仿星器实施协议下的国际合作实验。（1）项目规划和研究考察：多名研究人员访问欧洲，参加IEA国际执行仿星器会议，推动LHD国际相互实验（LIME）计划，以实现螺旋等离子体的高性能和稳态维持。（2）个人交流研究合作：为了展示这项资助研究的成果，一些科学家出国参加了国际会议，并与外国科学家进行了讨论。特别讨论了在等离子体约束、输运程序开发和未来合作计划方面的差异。（3）邀请与约束、诊断和反应堆有关的外国科学家：在该研究框架内，邀请了来自德国、瑞士、美国、俄罗斯等多位国外科学家，在等离子体约束、诊断和反应堆设计等方面开展了多种合作研究，这些研究合作得到了国际能源署（IEA）国际执行委员会的高度评价仿星器执行协议。
