On April 11, the ITER magnet feeder procurement package project of the international thermonuclear experimental reactor ushered in a key node. The last set of feeder components in the calibration field coil developed by the Institute of Plasma Physics of the Chinese Academy of Sciences Hefei Institute of Material Sciences was completed in Hefei and delivered to the ITER site. The completion and delivery of this component marks the successful completion of the development task for all oversized components in the ITER magnet feeder system. The picture shows the ultra large internal feeder of the International Thermonuclear Experimental Reactor magnet, with a diameter of 16 meters and a height of 3 meters, forming a semi-circular structure.
