(3) Reactor Concept Improvements. (Examples: Current drive In tokmaks, 

 mirrors, stellarators, RFP's, etc.) (Dr. A. Trivelplece, USA, Leader) 



Research on Improved plasma confinement concepts, both Improved 

 versions of the tokamak and alternative geometries, has resulted in 

 important advances in physics understanding, as well as the development 

 of approaches that show significant promise of an improved reactor 

 product. To a considerable extent, these programs are already 

 conducted in a cooperative and nonduplicative manner with different 

 emphases in different countries and bilateral agreements where 

 appropriate. 



Charge; This Subpanel should identify other opportunities to optimize 

 this endeavor within the limits of resources. 



Collaboration between programs can be implemented through different 

 mechanisms: complementarity in development, joint construction or 

 operation of facilities, cooperative experiments using facilities in 

 other nations, exchange of information or tools. 



For each scientific or technical item identified for possible 

 collaboration, please suggest the appropriate class of collaboration. 



Possible Examples: 



Complementarity: alternative approaches (mirrors, stellarators, 

 RFP, ...) development of advanced diagnostics, ceramics for 

 blankets, ... 



Joint construction or operation of facilities: FMIT, LCT, ALT II, 

 negative ions, energy recovery in neutral injection, ... 



Cooperative experiments using facilities in other nations: steel 

 irradiation data, ... 



Exchange of Information or tools: codes, physics data, ... 



Subpanel on Administrative Problems Affecting Fusion Cooperation 

 (Professor P. Fasella, European Communities, Leader) 



International cooperation in Controlled Thermonuclear Fusion Research would 

 benefit from some changes in certain fees and regulations in the areas of 

 customs, data and computer communications, and personnel exchanges. The 

 Working Group on High Energy Physics has established Subpanel s to examine 

 the facts and make recommendations in this area of administrative problems.
