Final Design of ITER In-Vessel Coils and Manufacturing of In-Vessel Coil Conductor / Encheva, Anna (ITER) ; Bontemps, Vincent (ITER) ; Fichera, Claudio (ITER) ; Laquiere, Julien (ITER) ; Macioce, Davide (ITER) ; Mariani, Nicola (ITER) ; Piccin, Roland (ITER) ; Tronza, Vladimir (ITER) ; Vostner, Alexander (ITER) ; Sgobba, Stefano (CERN)
Following a decision made at the ITER Council in November 2013, two types of in-vessel coils (IVCs), namely, edge-localized mode (ELM) coils to mitigate ELMs and vertical stability (VS) coils to provide vertical stabilization of the plasma, have been incorporated in the ITER baseline design. The in-vessel environment is severe, characterized by large transient electromagnetic fields, high radiation flux, and high temperature. [...]
