Superconducting Tokamak The Superconducting Magnet system consists of 16 TF(Toroidal Field) coils and 14PF(Poloidal Field) coils. Both of the TF and PF coil system use internally cooled superconductors. The TF coil system provides a field of 3.5 T at a plasma center, with a peak flux density at the TF coils of 7.5 T and the stored energy is 470 MJ. Incoloy 908 conduit and Nb3Sn superconducting cable are used for the TF CICC. The nominal current of TF coils is 35.2 kA with all coils in series. The PF coil system provides 17 V-sec and sustains the plasma current of 2 MA for 20 seconds inductively which consists of 8 coils in the CS(Central Solenoide) coil system and 6 outer PF coils. PF 1-5 coils use Nb3Sn CICC in Incoloy 908 conduit and PF 6-7 coils use NbTi CICC in a modified stainless steel 316LN.
