Title: Procurement and testing of superconducting toroidal field coils in the large coil program

Abstract

As part of the development of superconducting toroidal field coils for tokamak reactors, the U.S. Large Coil Program was established to accomplish the design, fabrication, and testing of large coils of competing designs, under conditions approximating those in a reactor. Three U.S. industrial teams are under contract to design and fabricate at least one coil each, to guidelines and specifications established by the Program. Concurrently a large coil test facility is being constructed at Oak Ridge. Each LCP test coil will have a 2.5 x 3.5 m D-shape winding bore and will operate with a conductor current of 10 to 16 kA, at a peak field of 8 tesla while subjected to pulsed fields up to 0.14 T and simulated radiation heating. Two test coils will use NbTi conductor; the other, Nb/sub 3/Sn. The required cryostabilization will be achieved in the NbTi coils by cooling with boiling helium; in the Nb/sub 3/Sn coil, by forced flow of supercritical helium. The arrangement chosen for the coil tests is a 6-coil compact torus, in which coils of different internal design can be assembled to generate the magnetic field required for realistic testing. The new facility will provide vacuum around the test stand,more » cryogenics, power, control and data systems.« less
