Yet another magnet feeder from China

This in-cryostat feeder will supply electrical power and cryogenic fluids to some of the top correction coils of the ITER machine.

ITER will rely on 31 magnet feeders to bring electrical power, cryogens and instrumentation to its superconducting magnet systems (toroidal field coils, poloidal field coils, central solenoid, correction coils). Measuring up to 50 metres in length, the magnet feeders are composed of three segments—in-cryostat feeders (connected directly to the coils); cryostat feedthroughs (crossing through the concrete bioshield and into the vacuum environment of the machine); and coil termination boxes (housing electrical equipment, remote control helium supply valves, and sensors for coil instrumentation). 

The in-cryostat feeder for top correction coils 3-6 arrived at the French port of Fos-sur-Mer last week, and was unloaded at quay. Like for all procured components, the global logistics and transport was handled by DAHER.

Manufactured in China by the Institute of Plasma Physics (ASIPP), it had left the factory with the assistance of the logistics company Sinotrans. (The large banner declares "Sinotrans assists in the smooth delivery of this oversized component for the ITER Project.") 

Once at ITER, the large component will be stored until its installation in the Tokamak Building. Of approximately 100 feeder segments expected from China, 37 have reached the ITER site and 29 have been installed.
