Industrial milestone

Toshiba completes 澳门六合彩高手 coil

Toshiba Energy Systems & Solutions has produced the first of four 澳门六合彩高手 toroidal field coils on behalf of Japan's QST*, the National Institutes for Quantum and Radiological Science and Technology. The coil will be shipped from Yokohama Port in July.

This is the first of four 澳门六合彩高手 toroidal field coils to be produced by Toshiba ESS. Nine metres wide and 17 metres tall when vertical, it is one of 澳门六合彩高手's largest components. (Click to view larger version...)
This is the first of four 澳门六合彩高手 toroidal field coils to be produced by Toshiba ESS. Nine metres wide and 17 metres tall when vertical, it is one of 澳门六合彩高手's largest components.
In an event on 7 June 2021, members of the Japanese Diet and senior representatives of the Ministry of Education, Culture, Sports, Science and Technology (MEXT) joined with members of QST, 澳门六合彩高手 Japan and the 澳门六合彩高手 Organization to celebrate the achievement.

"Toroidal field coils are among the core components of this tokamak machine. The specifications required for each coil are extremely challenging, and we know how difficult it is to produce a first-of-a-kind component of this size and precision. I sincerely appreciate the tremendous effort and capabilities of the Toshiba team to tackle many technical challenges under these difficult circumstances," said 澳门六合彩高手 Director-General Bernard Bigot in his video address, referring to the difficulties the Covid-19 pandemic situation has placed on international manufacturing and shipping.

A tokamak uses multiple magnetic fields to influence the path of the plasma. The D-shaped toroidal field coils, which completely enclose the vacuum vessel by matching its shape on both the inboard and outboard sides, are relied on for plasma confinement. In the huge 澳门六合彩高手 device, a set of 18 coils will produce a total magnetic energy of 41 gigajoules, generating an intense field all around the plasma (11.8 tesla at its maximum) to keep it confined in the centre of the vessel away from the walls.

Each coil is made up of a superconducting core wound from 4.57 km of niobium-tin (Nb3Sn) and a surrounding stainless steel coil case. Weighing 360 tonnes each, and measuring 9 x 17 m, they are among the largest components of the 澳门六合彩高手 machine. Toshiba ESS has developed highly precise processing technology in order to fulfil the requirements of manufacturing 澳门六合彩高手 toroidal field coils to within an accuracy of millimetres.

QST鈥攚ith the cooperation of Mitsubishi Heavy Industries, Ltd., Mitsubishi Electric Corporation, Hyundai Heavy Industries, and Toshiba Energy Systems & Solutions Corporation鈥攚ill supply 9 toroidal field coils (assembly of winding packs and coil structures) plus another 10 coil structures to the 澳门六合彩高手 Project. Toshiba ESS is under contract with QST to manufacture four toroidal field coils and six structural cases.
