Helical Confinement Data - Base and Configuration Optimization

螺旋聚变系统由于没有等离子体电流中断和可靠的稳态操作而比托克马克型装置具有主要优势。为了实现更好的聚变反应堆，发展螺旋系统的等离子体约束是非常重要的，世界上最大的螺旋机LHD（Large Helical Device）已经在日本开始运行，温德尔斯坦7 - X（W7 - X）正在德国建造。两个项目的相互讨论是非常有益的。在作为文部省国际科学研究计划资助的2年研究合作期间，我们完成了以下项目：（1）研究协调和计划：在德国、西班牙、美国、日本、日本等国，（2）约束分析与螺旋反应器设计：IPP - Garching的几位研究人员讨论了实验数据库和分析方法。(3)先进的磁结构优化：来自德国和俄罗斯的一些研究人员帮助我们优化螺旋系统。(4)关于螺旋研究活动的世界范围调查：就理论和实验问题进行了个人交流。应该指出的是，在这项赠款活动的基础上，LIME计划获得批准，并从1998财政年度开始实施。

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 .The world - largest helical machine , Large Helical Device ( LHD ) has started plasma operation in Japan , and the Wendelstein 7 - X ( W7 - X ) is being constructed in Germany . It is very useful to discussed with each other for both projects .During 2 - years research collaboration period as a Grant under the Monbusho International Scientific Research Programs , we performed the following items : (1) Research coordinating and Planning : Discussion about the LHD International Mutual Experiment ( LIME ) Program and the related international research collaboration have been carried out in Germany , Spain , France and so on. (2) Confinement Analysis and Helical Reactor Design : Several researchers from IPP - Garching discussed experimental database and analysis methods . (3) Advanced Magnetic Configuration Optimization : Some researchers from Germany and Russia helped us optimize helical system . (4) World - Wide Survey on the helical research activity : Personal exchanges have being carried out for theoretical and experimental issues .It should be noted that based on this Grant activities the LIME program was approved and started from Fiscal Year 1998 .
