Abstract

In the framework of the Broader Approach Agreement between Europe and Japan for the construction of the JT-60SA tokamak in Naka, Japan, ENEA is committed to supply nine toroidal field (TF) superconducting magnets. The supply is carried out via a contract awarded in 2011 to ASG Superconductors, in which all the qualification activities have been accomplished and the manufacturing has already considered every step of fabrication. Six of the foreseen winding packs (WP) have been already wound, vacuum pressure impregnated and tested; the subsequent phase of the fabrication, consisting in the into casing insertion of the WP, has started. The critical processes have been qualified through the use of dedicated mock-ups. To carry out the insertion operation a dedicated tooling has been designed and installed in ASG. It consists of a central core on which the WP is grasped and of two lateral carriages for the casing component approaching in horizontal position. The present paper describes the WP manufacturing process highlighting some issues as the dimensional tolerances and the electrical insulation under vacuum. The final phase of fabrication, consisting in the into casing insertion of the WP, will be reported describing all the steps to arrive at the completion of the first TF coil.
