In regard to the future, there are a number of opportunities to 

 enhance international collaboration consistent with a strong and 

 effective U.S. magnetic-confinement fusion program. One area is the 

 possibility for collaboration on a large-scale, next-step fusion de- 

 vice. In addition, the U.S. program is pursuing a variety of oppor- 

 tunities that will strengthen specific elements of its program. 

 Joint work with the European Community in the impurity control area 

 on ASDEX-Upgrade (the Federal Republic of Germany), through the Ad- 

 vanced Limiter project (ALT-III) on TEXTOR (the Federal Republic of 

 Germany), and potentially on the new long pulse device. Tore Supra 

 (France) provides examples of international activities that strength- 

 en the U.S. program. This is also true in regard to the Doublet-Ill 

 facility and in supporting concept approaches such as the tandem mir- 

 ror and stellarator facilities. 



See table 3 for a list of magnetic-confinement fusion facili- 

 ties and appendix 4 for brief descriptions of each of these facili- 

 ties. Vll 



B. INERTIAL-CONFINEMENT FUSION 



In the area of Inertial-conf inement fusion, eight (six U.S. 

 and two foreign) facilities have been identified, also see table 3 

 and appendix 4. There may be significant opportunities for interna- 

 tional cooperation at the National Laser Users Facility ("OMEGA") of 

 the University of Rochester, the GEKKO XII glass laser system at 

 Osaka University in Japan, and the Central Laser Facility ("VULCAN") 

 of the Rutherford Appleton Laboratory in the United Kingdom. The 

 other U.S. facilities are Government facilities involved in research 

 associated with national defense.
