JOINT EUROPEAN TORUS (JET) 



Culham 



EURATOM and the European Community 



"Big Science" Descriptor : Magnetic fusion 



Description of Facility/Instrument : JET is the world's largest 



tokamak. It is designed to achieve reactor grade plasmas in 

 order to provide the information necessary to build the Next 

 European Tokamak (NET). It is equipped with 20 megawatts of ion 

 cyclotron radio frequency (ICRF) heating and 15 megawatts of 

 neutral beam heating. It also is designed with a tritium handling 

 capability. If the plasma conditions are sufficient, this cap- 

 ability will be used to create deuterium-tritium plasmas, 

 which will make it possible to study alpha particle effects. 



Date of Construction ; 1983 



Construction Cost ; 1984 $$ ; $660 million in current dollars 



Present International Cooperation 



Natlonallty(s) of Ownership ; European Community 

 Nationallty(s) of Operational Funding : European Community 

 Nationallty(3) of Management Staff ; European Community 

 Nationality(s) of Researchers : European Community. At present, 



the U.S. collaboration with JET has been limited to exchanges 

 of information and personnel. The personnel exchanges have 

 been at the two to three man-years per year rate. 



JET represents a major triumph of international col- 

 laboration in fusion. The ten member states of the European 

 Community were able to develop a coordinated approach to 

 their next major step, and conceived a Joint Undertaking for 

 the JET project. 



Other Information ; Construction of JET began in 1977 and will end in 

 1987 when full capability is achieved. The total budgeted con- 

 struction cost is 533 million ECUs . Most of the funds were spent 

 between 1978 and 1983. The DOE estimate of the cost in current 

 (that is, year of expenditure) U.S. dollars is $660 million. The 

 cost figures for JET may not Include all of the commissioning and 

 R&D costs.
