| Winding the first coil of electromagnet |
General Atomics in Poway officially began production of a new 1,000 ton superconducting electromagnet to be used as part of the ITER experimental fusion energy experiment, which will be conducted in France. ITER is a partnership between several countries with the ultimate goal of demonstrating the scientific and technological feasibility of fusion energy. Countries involved in ITER, which will take place in St. Paul-lez-Durance, France, include the United States, China, the European Union, India, Japan, South Korea and the Russian Federation.

Magnet system
The central solenoid coil will use superconducting niobium-tin to carry 46 kA and produce a field of up to 13.5 teslas. The 18 toroidal field coils will also use niobium-tin. At their maximum field strength of 11.8 teslas, they will be able to store 41 gigajoules. They have been tested at a record 80 kA. Other lower field ITER magnets (PF and CC) will use niobium-titanium for their superconducting elements. |

It is the place where 34 nations representing more than half the world’s population have joined forces in the biggest scientific collaboration on the planet – only the International Space Station is bigger.
The international nuclear fusion project – known as Iter, meaning “the way” in Latin – is designed to demonstrate a new kind of nuclear reactor capable of producing unlimited supplies of cheap, clean, safe and sustainable electricity from atomic fusion.

GA is building seven modules for the magnet at its facility in San Diego; one of these is a spare part. Each module is 4.1m in diameter and 3m high, and contains 6km of niobium-tin (Nb3Sn) alloy superconducting wire wound onto a stainless steel core, giving it total mass of around 120tonnes. The total height of the CS is 18m — the entire height of the ITER reactor — and it will be cooled to a few degrees above absolute zero in operation. GA expects to be winding consuctor onto the module cores until 2017. It will be in place in the reactor at Cadarache, near Marseilles, by 2019.
