INTERNATIONAL FUSION SUPERCONDUCTING MAGNETIC TEST FACILITY (IFSMTF) 

 Oak Ridge National Laboratory (ORNL) 

 U.S. Dept. of Energy 



"Big Science" Descriptor : Magnetic fusion 



Description of Facility/Instrument ; This is a facility to evaluate 

 the performance features of six large-scale superconducting 

 magnets designed and manufactured by both U.S. and foreign 

 industrial concerns. The magnets are arranged in a toroidal 

 array in the IFSMTF and tested individually and collectively 

 to investigate scalable magnetic coupling effects and forces 

 on the coil structures and the superconductors. 



Date of Construction : 1983 



Construction Cost : 1984 $$ : $36 million in current year dollars 



Present International Cooperation 



Nationality(s) of Ownership ; U.S. ovms and operates the facility; 



three coils are foreign-owned. 

 Nationality(s) of Operational Funding ; U.S. 

 Nationality(s) of Management Staff ; U.S. (International Executive 



Committee for the Large Coil Task) 

 Nationality(s) of Researchers : U.S., Japan, Switzerland, EURATOM 



The IFSMTF at ORNL is one of two major interrelated 

 tasks under the Large Coil Test (LCT) organized in 1977 

 as an international cooperative program to develop, test, 

 and demonstrate steady-state 8 Tesla field superconducting 

 magnet coils. The other task under the LCT is the design 

 and manufacture of six large superconducting coils which 

 will be tested in the facility. Three of the large coils 

 are fabricated by U.S. industry and three by foreign par- 

 ticipants (Japan, Switzerland, EURATOM) under the formal 

 International Energy Agency agreement. 



The total cost of the six coils is estimated to be 

 $6-$7 million, which includes the costs of development.
