![]() ![]() Inserting the ITER Winding Pack in the coil cases at SIMIC, Marghera, Italy, 2019. SIMIC and subcontractor Babcock Noell (now Bilfinger Noell) took on the final production steps in Marghera (Italy), which included cold testing, insertion of the winding pack into a structural stainless steel case, and closure welding and machining.Winding Pack of an ITER toroidal field coil at ASG Superconductors in La Spezia, Italy. ITER TFC Double Pancake and Winding Pack. They are then wrapped, and electrically insulated with glass and Kapton tape to form a Winding Pack (WP). Seven DP are stacked and electrically jointed. ![]() The DP is wrapped and electrically insulated with glass & Kapton tape before impregnation with epoxy resin. Cover plates are fitted and laser welded in order to close the grooves where the conductor is allocated, resulting into a Double Pancake (DP). The cable is then extracted from the radial plates, wrapped and electrically insulated using several layers of glass and Kapton tape, and re-positioned in the radial plate groove. Because the conductor uses brittle Nb3Sn, the coil is wound with a cable made of a precursor of the superconductor and then undergoes a heat treatment at 650 ☌ in inert atmosphere during one month. 750 m of conductor are bent to fit into the grooves of the radial plate. An international consortium led by Iberdrola Ingeneria, together with Elytt Energy and ASG Superconductors produced the 10 superconducting Winding Pack (WP) in La Spezia, Italy.Two pre-machined ITER Radial Plates at CNIM, Toulon, France, 2014. ![]() CNIM and SIMIC produced the equipment to insert the conductor into the magnet in Toulon (France) and Marghera (Italy), respectively. The role of the radial plate is to withstand the Lorentz forces acting on the conductor and to accurately place it.
