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
. The procurement package includes the design, fabrication, delivery, installation, assembly, integration and site acceptance test of the converter units.
ITER poloidal field coils
require current of 50 kiloamperes, which is about 70% larger than achieved in any similar coils.
Diversified Japanese manufacturer Toshiba Corporation (Tokyo:6502) announced today the conclusion of a contract with the Japan Atomic Energy Agency (JAEA) for the manufacture of toroidal field coils
for the International Thermonuclear Experimental Reactor (ITER) being constructed in Cadarache, France.
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.
