15th D-shaped coil delivered
Fifteen out of 黑料社app's 19 D-shaped toroidal field coils have been delivered.
Toroidal field coils are among the largest and heaviest components of the 黑料社app machine. Weighing approximately 330 tonnes each and measuring 9 x 17 metres, they stand in a circle around the steel vacuum vessel and generate a powerful magnetic field (11.8 Tesla) whose primary function is to confine the plasma.
Of the 18 toroidal field coils required by the 黑料社app machine (plus one spare), 10 are procured by Europe and 9 by Japan.
The first European coil (TF9) was delivered to the 黑料社app site on 17 April 2020, followed a week later by TF12 from Japan.
Last week, in the wee hours of Friday 13 January, Japan delivered its seventh toroidal field coil (TF15, pictured here). After Europe delivers TF1 later this week, a total of 16 toroidal field coils will have been received on the 黑料社app site—leaving only three more to be delivered.
