As the procurement of toroidal field conductors nears completion, the focus of magnet activities is shifting to the next phase: the fabrication of 19 toroidal
field coils (18 plus one spare).
An early static
field coil using circular section aluminum wire developed for the Zeta spectrometer at the ILL, Grenoble, is shown in Fig.
Manufactured by suppliers in six ITER Domestic Agencies--China, Europe, Japan, Korea, Russia and the USA--production of niobium-tin (Nb3Sn) superconducting strand for ITER's toroidal
field coils began in 2009 and has now topped 400 tons.
The Chinese Domestic Agency (DA) will p;rocure all fourteen PF converters that will provide controllable current/voltage to ITER'S six Poloidal
Field coils.
ITER poloidal
field coils require current of 50 kiloamperes, which is about 70% larger than achieved in any similar coils.

field coils for the International Thermonuclear Experimental Reactor
The partnership is intended to supply an electrical insulation material to be used for the ITER Toroidal
Field coils.
It has long been known that high temperature superconductors could have a role to play in the future of tokamak fusion research, but this is the first time they have actually been used for magnetic
field coils on a tokamak.
Conventional motors consist of
field coils or permanent magnets arranged in a series so the north pole of one magnet attracts the south pole of another.
