MANUFACTURING OF THE LN 2 COOLED TOROIDAL COILS OF FTU

The FTU Tokamak in order to reach the expected performance will have to operate at very high levels of magnetic fields for a large number of shots. The Toroidal Magnet will under go very high stresses due to thermal and electromagnetic loads and provide the basic mechanical structure supporting all the poloidal field windings and the vacuum vessel. The manufacturing of the magnet started on July ‘85 at the Ansaldo Componenti works in Genova for delivery at the beginning of ‘87.
