Present Status of the KSTAR Superconducting Magnet System Development

The mission of korea superconducting tokamak advanced research (KSTAR) Project is to develop a steady-state-capable advanced superconducting tokamak for establishing a scientic and technological basis for an attractive fusion reactor. Because the KSTAR mission includes the achievement of a steady-state-capable operation, the use of superconducting coils is an obvious choice for the magnet system. The KSTAR superconducting magnet system consists of 16 TF (toroidal eld) and 14 PF (poloidal eld) coils. Both of the TF and the PF coil systems use internally cooled cable-in-conduit conductors (CICC). The TF coil system provides a eld of 3.5 T at the plasma center, and the PF coil system is able to provide a ux swing of 17 V-sec. The major achievements in the KSTAR magnet system development include the development of CICC, the development of a full-size TF model coil, the development of a background magnetic eld generation coil system, and the construction of a large-scale superconducting magnet and CICC test facility. The TF and The PF coils are being fabricated for the KSTAR completion in the year 2005. KCI Citation Count: 1
