FINAL REPORT 



SUMMIT WORKING GROUP ON FUSION 



SUBPANEL FOR NEAR-TERM FUSION PHYSICS AND TECHNOLOGY 



PHYSICS SUBGROUP 



1. INTRODUCTION 



- The strengthening of the bilateral or lEA agreements already existing 

 on near term specific objectives, and the conclusion of new agreements 

 of a similar nature, would be appropriate both in a short term 

 perspective in order to make the solution of present technical and 

 administrative problems easier, and in the longer term in order to 

 prepare the conditions for cooperation on major new facilities. 

 Subpanel 2 has been charged to identify key areas where increased 

 collaboration would be most beneficial, both on present and planned 

 facilities. Subpanel 2 is divided in 3 subgroups: Physics 

 {essentially conventional Tokamaks, heating, diagnostics, codes). 

 Technology, and Reactor Concept Improvements. 



- To fulfill its task, the Physics Subgroup, having reviewed the main 

 physics facilities in operation or in construction in the different 

 countries (Appendix 1), has considered: 



the cooperative actions in progress (paragraph 2); 



possible cooperative actions which have already been the 

 object of preliminary discussions (paragraph 3); 



and indicated in which specific areas an increased collaboration 

 would be possible and particularly useful (paragraph 4). 



- The composition of the Physics subgroup is given in Appendix 2. 



2. COOPERATIVE ACTIONS ALREADY IN PROGRESS 

 2.1 In the frame of the lEA. 



- TEXTOR (FRG) 



The implementing agreement on plasma-wall interaction in Textor has 

 been very successful. It led to an effective participation of 

 American, Canadian, Japanese and Swiss physicists in the Textor 

 experiment, accompanied in several cases by transfer of hardware. A 

 second step in the pumped limiter programme ALT II is in an 

 advanced stage of preparation.
