项目摘要

Helical fusion systems have major advantages over Tokamak-type devices because of no plasma current disruptions and reliable steady-state operations.For achieving better fusion reactors, it is important to develop the plasma confinement of helical systems.At present in Japan, the LHD (Large Helical Device) is under construction, and the CHS (Compact Helical System) is in operation.On the other hand, In Germany, the W7-X (Wendelstein7-X) project has been approved and the W7-AS experiments are being carried out.It is very useful to discussed with each other for both projects.Several Japanese scientists visited IPP-Garching to discuss the following items :(1) Comparisons between LHD Project and W7-X PlanningThe concepts of plasma confinements in both projects are compared and checked.Moreover, superconducting coil conductors for both projects are compared.(2) Comparisons between CHS and W7-AS experimentsExperimental data from two devices are discussed, and the confinement models are checked.(3) General confinement theory for helical systemsPersonal exchanges have been carried out for helical confinement theory.Moreover, several scientists visited Germany and Spain for getting information on the German stellarators and the Spanish TJ-II heliac project, as well as to discuss on the future research collaboration plan.In the next fiscal year, these collaboration researches should accelerated as a Grant under the Monbusho International Scientific Research Programs.

螺旋融合系统与tokamak型设备具有很大的优势，因为没有等离子体当前的干扰和可靠的稳态操作。对于实现更好的融合反应器，在日本存在的血浆限制的情况下，重要的是在日本存在的血浆限制。 (Wendelstein7-X) project has been approved and the W7-AS experiments are being carried out.It is very useful to discussed with each other for both projects.Several Japanese scientists visited IPP-Garching to discuss the following items :(1) Comparisons between LHD Project and W7-X PlanningThe concepts of plasma confinements in both projects are compared and checked.Moreover, superconducting coil conductors for both projects are compared.(2) Comparisons between CHS and W7-AS experimentsExperimental data from two devices are discussed, and the confinement models are checked.(3) General confinement theory for helical systemsPersonal exchanges have been carried out for helical confinement theory.Moreover, several scientists visited Germany and Spain for getting information on the German stellarators and the Spanish TJ-II heliac project, as well as to discuss on the future research collaboration计划。在下一个财政年度，这些合作研究应加速作为Monbusho国际科学研究计划的赠款。
