| Abstract: | As the step of development of superconducting tokamak toroidal magnet system, a Cluster Test system is being constructed. The test facility has two coils, called cluster test coil (CTC), in a sector position, which provides back-ground field to a test module coil (TMC). The oval-shaped TMC has a mean width of 1.5 m and a mean height of 2.0 m. And it is designed to operate at a peak field of 8 T and an average current density of 3 KA/cm2on the winding space when CTC, operated with rated current, has 7 T as a peak field with current density of 3 KA/cm2. Experience on the Cluster Test will provide fabrication techniques and verifications of computer codes for future toroidal coil design principles. |
