World’s largest fusion reactor hits magnet feeder gallery milestone

The ITER fusion project has achieved a significant milestone with the installation of the 62nd and final "gallery" component of its magnet feeder system. These components are critical for the operation of the superconducting magnets, as they transport cryogenic fluids, power, and instrumentation from the warm exterior environment to the magnets operating at extremely low temperatures (-270°C). The magnet feeder system is a large-scale installation within the Tokamak Complex, consisting of nearly 100 components weighing around 1,600 tonnes, with some feeders extending up to 40 meters in length. The system includes 31 components that supply the toroidal, poloidal, central solenoid, and correction magnet coils. The assembly team distinguishes between two types of feeder segments: "gallery" components located outside the cryostat and "in-cryostat" segments inside the cryostat that connect directly to the magnets. The recent completion of the gallery portion involved installing all 31 coil termination boxes and 31 cryostat feedthroughs, marking a
