A first study, carried out by Ansaldo Superconduttori, addressed the manufacturing sequence, assuming the manufacture of the PF coils inside the two buildings which will further host the cryogenic system. A second study, carried out by Alstom investigated how to achieve the manufacture of some crucial points. A new layout of the manufacturing line was proposed, aiming at manufacture of the PF2–6 coils within 36 months. A recent study performed by Alstom, assumes the manufacture of the PF coils in a single dedicated building, releasing so the constraint of meeting the deadline fixed in ITER reference scheme by the starting point of installation of the cryogenic components.
