Magnet scenario design and analysis for ITER

ITER (International Thermonuclear Experimental Reactor) is a collaborative design by the United States, Europe, Japan and the Soviet Union for a tokamak fusion reactor that would demonstrate the physics and test the technology needed for commercial fusion reactors. The poloidal field (PF) magnets are responsible for forming and shaping highly elongated, high-current plasmas during a long-pulse burn. The toroidal field (TF) system consists of 16 magnets with single-grade, rectangular winding packs. The conductor is an internally-cooled, ternary Nb/sub 3/Sn. This conductor is also used in the high-field PF coils. All PF coils external to the TF system are superconducting, using internally-cooled, cable-in-conduit conductor. >
