On January 26 2021, the coil terminal box of the feeder serving toroidal field coils #12 and #13 was placed into position in the gallery at the lowest level (B2) of the Tokamak Building.

From the outside, a magnet feeder looks like a large box from which a fat pipe emerges that decreases in cross section the closer it gets to the centre of the machine. Arranged in a circle at both the lower and upper levels of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Tokamak, the 31 magnet feeders* are like giant syringes all aiming in the same direction.
Twenty-one feeders, out of a total of 31, will be installed in the lower basement level (B2) of the Tokamak Building. In green at centre-left is the feeder serving toroidal field coils #12 and #13.
Procured by China and manufactured at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP), each feeder segment is delivered to °ÄÃÅÁùºÏ²Ê¸ßÊÖ fully instrumented and, following onsite inspections and testing, ready for assembly—in all more than 1,600 tonnes of equipment and 93 large components plus auxiliaries.
