Helical Confinement Data - Base and Configuration Optimization

螺旋聚变系统与托卡马克型装置相比，由于没有等离子体电流中断和可靠的稳态运行，具有很大的优势。为了获得更好的聚变反应堆，发展螺旋系统的等离子体约束是很重要的。世界上最大的螺旋机大螺旋装置（Large helical Device， LHD）已在日本启动等离子体运行，德国正在建造Wendelstein 7 - X （W7 - X）。这是非常有用的相互讨论两个项目。在为期2年的蒙布修国际科学研究计划研究合作期间，我们进行了以下工作：(1)研究协调与规划：在德国、西班牙、法国等国进行了LHD国际相互实验（LIME）计划的讨论及相关的国际研究合作。(2)约束分析和螺旋反应器设计：IPP - Garching的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了螺旋系统。(4)螺旋研究活动的全球概况：就理论和实验问题进行了个人交流。应该指出的是，在这些赠款活动的基础上，LIME项目获得批准并从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 .
