Abstract :
The poloidal field (PF) coils and correction coils (CCs) constitute one of the four hydraulic loops of the ITER magnet system. They are cooled in parallel by the same heat exchanger. The PF coils consist of 6 different pulsed coils while the CCs include 18 coils divided into 3 different sets: bottom, side and top. The PF coils are made of dual-channel NbTi conductors whereas the CCs consist of single-channel NbTi conductors. The SuperMagnet suite of codes can combine 1-D cooling with supercritical helium flow in the ITER conductors and the 2-D heat diffusion across the coils into a full-scale quasi 3-D model. We analyzed the in-coil NbTi conductor performance and the heat load to the cryogenic plant. We also compared the results from Vincenta and SuperMagnet.
