  5. ＪＩＦＴの目的（１） 核融合理論分野における日米共同研究や研究交流の推進を目的として、1981(昭和56)年日米政府間で日米科学技術協力事業（核融合分野）、日米理論共同研究（ＪＩＦＴ＝Joint Institute for Fusion Theory）に関する協定が締結された。 • The purpose of the JIFT is to facilitate exchange of ideas and collaborative research between American and Japanese scientists engaged in theoretical fusion research. The JIFT incorporates a U.S. component, hosted by the Institute for Fusion Studies (IFS), University of Texas, and a Japanese component, hosted by the International Centre for Fusion Theory (ICFT), Institute of Plasma Physics (IPP), Nagoya University. • These two components comprise the core of the JIFT. Other institutions and individuals engaged in theoretical fusion research participate in JIFT activities as appropriate. ANNEX II （May 1, 1981 ）

  6. ANNEX TO AGREEMENT ON ACADEMIC EXCHANGE AND COLLABORATION BETWEEN NATIONAL INSTITUTE FOR FUSION SCIENCE, JAPAN AND INSTITUTE FOR FUSION STUDIES THE UNIVERSITY OF TEXAS AT AUSTIN, USA • The purpose of the JIFT is to facilitate exchange of ideas and collaborative research between Japanese and U.S. scientists engaged in theoretical fusion research, which was originally established in 1981 through an Annex to the Official Record of Agreement between the Japan Ministry of Education and the U.S. Department of Energy. The JIFT incorporates a Japanese component, hosted by the National Institute for Fusion Science (NIFS), and a U.S. component, hosted by the Institute for Fusion Studies (IFS) of the University of Texas at Austin. These two components comprise the core of the JIFT. Other Japanese and U.S. institutions and individual scientists engaged in theoretical fusion research also participate in JIFT activities as appropriate. 学術交流協定（March 6, 2006）

  7. 学術交流協定調印式（March 6, 2006） Signing ceremony: J. Van Dam and O. Motojima

  8. ＪＩＦＴの目的（２） • to advance the theoretical understanding of plasmas (stability, equilibrium, heating, and transport in magnetic fusion systems), • to develop fundamental theoretical and computational tools and concepts for understanding nonlinear plasma phenomena.

  17. JIFT の実績表

  18. Comments by J. W. Van Dam • Workshop • Inequality in number of participants  due to tight budget in US side • Remote participants via international telecommunication system • Joint sponsorship with other meeting  JIFT workshop as a satellite meeting of a big conference such as ICPP • Involution of young scientist in organizing workshop • Personal exchange • Participation of an advanced graduate student • Periods of visiting professor  more than 3 months in Japan, less than 3 months in US • Joint computational projects • Data link between US (LLNL) and Japan (JAERI,NIFS) was stopped around 1999(?)  useful and needful • Shift to another purpose  support JIFT workshop and exchange visit and enlarge JEARI (JAEA) participation

  19. 実績のまとめ • 最新の理論研究、シミュレーション研究、数値技法、その動向に関する効果的な情報交換の機会 • 関連分野（流体、統計物理、計算物理、宇宙物理等）からの参加が、新しい科学技術情報や学問潮流の交流を促進、核融合プラズマ物理への成果の導入をもたらした。 • 大規模シミュレーション手法、計算機アルゴリズム等の情報の相互交換、関連施設の使用の機会 • ＪＩＦＴに関連した多数の論文の出版、ＩＡＥＡ国際会議を始めとする国際会議での成果発表 • 緊密で長期に亘る共同研究の基盤構築、そのための人的なネットワークの形成 • 日米双方の核融合分野の研究者、とりわけ、若手研究者に共同研究の機会を与え、核融合分野の研究者の育成に貢献
