ASDEX 



Institute of Plasma Physics 



Federal Republic of Germany and EURATOM 



"Big Science" Descriptor : Magnetic fusion 



Descr iption of Facility/Instrument : ASDEX is a medium-sized tokamak. 

 Its primary objective is to study the effect that a poloidal 

 divertor has on the plasma. ASDEX has three megawatts of ion 

 cyclotron radio frequency (ICRF) and three megawatts of neutral 

 beam heating- The ASDEX group had made significant contributions 

 to the understanding and enhancement of tokamak performance. It 

 was the first device to achieve performance with auxiliary heating 

 that was comparable to performance with ohmlc heating. 



Date of Construction ; 1979 



Construction Cost ; 1984 $$ ; $50-$70 million 



Present International Cooperation 



Nationallty(s) of Ownership ; Federal Republic of Germany 

 Natlonallty(s) of Operational Funding : Federal Republic of Germany 

 Nationality(s) of Management Staff : Federal Republic of Germany 

 Nationallty(s) of Researchers : Federal Republic of Germany. The 



United States supports exchanges of people with ASDEX at the 



three to four man-years per year rate. 



Potential for Future International Cooperation ; The United States and 

 the European Community /Federal Republic of Germany are now com- 

 pleting negotiations for a formal collaborative agreement on the 

 use of this facility. The United States currently has $1 million 

 budgeted for collaboration.
