Present status of the KSTAR superconducting magnet system development

Summary form only given, as follows. The Mission of Korea Superconducting Tokamak Advanced Research (KSTAR) Project is to develop a steady-state-capable advanced superconducting tokamak for establishing a scientific 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 Field) and 14 PF (Poloidal Field) coils. Both of the TF and PF coil system use internally-cooled Cable-In-Conduit Conductors (CICC) The TF coil system provides a field of 3.5 T at a plasma center and the PF coil system is able to provide a flux swing of 17 V-sec. The major achievement in KSTAR magnet system development includes the development of CICC, the development of a full size TF model coil, the development of a background magnetic field generation coil system, the construction of a large scale superconducting magnet and CICC test facility. TF and PF coils are in the stage of the fabrication for the KSTAR completion in the year 2005.
