Design and Manufacture of a NbTi Insert Module Relevant for the ITER PF Magnets Conductor

摘要

A NbTi insert coil has been manufactured to give a contribution, through its characterisation, to the discussion about the better layout of the full-size conductor for the Poloidal Field Coils for the ITER machine. The coil has been designed and constructed by ENEA and Ansaldo CRIS, with a conductor provided by Europa Metalli Superconductor and consisting of 36 Ni-coated strands twisted in a three-stage cable, jacketed and compacted in a SS round tube. A self consistent unit has been manufactured assembling the insert module and its mechanical supporting structure, to allow easy installation inside the background magnet of the ENEA test facility where the coil will be tested under representative conditions for the ITER PF magnets. The design and the description of the manufacturing process is presented in this paper, together with an overview of the experimental facility.
