On the basis of extension from the last year, Japanese and German scientists take part in the experiments of high-power millimeter wave transmission and Injection to Large Helical Device in NIFS, W7-AS, Asdex-U and W7-X in Max-Planck Institute for Plasma Physics supported by Institute of Plasma Research in Stuttgart University.The research subjects are as follows : to solve an arcing in the corrugated waveguide and to develop the power monitor and to discussed the results from the heating experiments. On the basis of experience at Stuttgart University, we fabricate the prototype arc detector and discriminator at the multi-observation stations and the power monitor. We have the dialogue on fabrication technique, which is the electric discharge machining, for the multi-ho1e power monitor. The experimental test of the power monitor satisfies the specification and its monitor is being used in the LHD.To monitor the polarization by use of this multi-hole coupler is discussed with the preliminary design.By exchange of mutual high technology, the object is almost achieved and we evaluate that the International collaboration is succeeded. Both team agreed that the remaining items are solved by the exchange of the information.

在去年扩展的基础上，日本和德国科学家在德国斯图加特大学等离子体研究所的支持下，参加了马克斯-普朗克等离子体物理研究所的NIFS、W7-AS、Asdex-U和W7-X大螺旋装置的高功率毫米波传输和注入实验，研究内容如下：解决了波纹波导中的电弧放电问题，研制了功率监控器，并讨论了加热实验的结果。在斯图加特大学的经验的基础上，我们制作了原型电弧检测器和在多个观测站和功率监测器的示波器。我们就多孔功率监视器的制造技术，即电火花加工进行了对话。该功率监测器的实验测试符合技术要求，已在铲运机上使用。本文结合初步设计，讨论了利用多孔耦合器进行偏振监测的问题。通过相互间的高技术交流，基本达到了预期的目的，并评价了国际合作的成功。两个小组一致认为，其余项目通过交换信息解决。
