o Development facilities (cryogenics, background coils, and so 



forth) for very high field magnet development. 



o Neutral-beam and radio-frequency test stands. 



o Tritium-handling facilities, 



o Blanket-technology facilities, 



o Liquid-metal loops and experimental facilities. 



o High heat flux test facilities. 



Another possible joint project, which has been highly successful in 

 the United States, is a computer facility for large-scale plasma and 

 facility modelling. Such a joint resource would similarly provide 

 benefits to other large-scale world programs. 



RECAPITULATION 



There is sufficient similarity in the status of development and near- 

 to intermediate-term objectives of the major world fusion progreuns to 

 provide a technical basis for major international collaboration in the 

 future. A long tradition of cooperation at the level of information 

 and personnel exchange, gradually increasing to the level of joint 

 programs on particular national facilities, shows that past 

 cooperation provides a sound basis for future efforts. Instances of 

 currently successful cooperation give confidence that larger 

 cooperative efforts in the future would also be successful. 



All the world programs have need for basic information in the 

 physics of plasmas near fusion conditions; for the development of the 

 numerous technologies necessary for fusion devices; and for the 

 design, construction, and operation of major experimental facilities. 

 Meetings, workshops, and personnel exchanges will continue to 

 disseminate useful information about plasma science and the individual 

 fusion technologies. In addition, larger-scale collaboration on joint 

 projects in reactor-relevant physics and technology would also 

 contribute to the solution of those technological problems. Finally, 

 in designing, building, and using the major experimental facilities, 

 there is ample opportunity for joint planning and joint undertakings.
