FTU toroidal and poloidal coils
Frascati (Italy), 1987
FTU is a tokamak for nuclear fusion research, installed at the ENEA Centre of Frascati in 1987. The Company manufactured all toroidal (26) and poloidal coils (14), the coupling transformer, the electrical connections and took care of the final integration of the load assembly. Each toroidal coil is obtained from 42 wedge shaped copper disks, cooled down to -195° C. The particular shape of the coils and of their austenitic steel housing has caused machining and assembly problems and ground insulation difficulties, since earthing must be according to a peculiar geometrical shape exposed to high mechanical stresses. The poloidal coils are in spiral shaped 100 x 3.4 mm copper plate insulated with glass, kapton and epoxy resin. An additional circuit provides for liquid nitrogen cooling
