Abstract
The stability in cable-in-conduit conductors subjected to varying field has been experimentally investigated to obtain a data base for conductor design of the ITER coils. The conductors of the ITER-coil are designed with cable-in-conduit conductors and will be subjected to varying field due to plasma disruption during the operation of the ITER. The varying field has a maximum amplitude of 2 T with the time constant of 57 ms on a maximum background field of 13 T. For this investigation, a plasma disruption simulation test facility has been constructed. The facility consists of two coaxial coils wound with a Nb3Sn wire. Test samples are installed between both coils. The facility can apply 2 T with a time constant of 10 – 71 ms to test samples at a background field of 13 T. Four kinds of test samples, which consist of 12 strands inserted within the titanium conduit have been constructed and tested using this facility. From these tests, it was found that the designed ITER conductors were stable with respect to plasma disruption during ITER operation.
