The ITER burning
plasma is expected to reach 150 million °C. How are we going to confine it?
superconducting magnets, known as Toroidal Field coils, will be powered with 68
000 A to generate a magnetic field of 11.8 Tesla (approximately 1 million times
stronger the magnetic fields of the Earth!). In this “cage” we will entrap the
energy of a small sun.
Europe will manufacture ten of the TF coils and Japan will
produce eight plus one spare. They will be the biggest Niobium-tin (Nb3Sn)
magnets ever produced. More than 600 people from 26 companies have collaborated
with F4E, managing the European contribution to ITER, to produce the ten TF
F4E has visited the premises of ASG Superconductors, where the
core components of the TF coils are manufactured. For the first time-ever, we
get to see the main fabrication steps and to meet the people behind the key operations.
Alessandro Bonito-Oliva, F4E Magnets Project Manager; Robert
Harrison, F4E Technical Officer; Marc Cornelis, F4E Technical Officer, offer us
a guided tour and explain how we have succeeded in manufacturing the most high-tech
magnets in history!
