Test Results of a 27-Cm Bore Multifilamentary Nb3Sn Solenoid
Future-controlled thermonuclear reaction (CTR) machines will undoubtedly require high-field superconducting magnets for plasma confinement. Although the maximum magnetic field that the superconductor windings will experience will depend on the particular confining magnet geometry and details of the magnet design, a recent conceptual design study made at Lawrence Livermore Laboratory (LLL) for a fusion engineering research facility (FERF)  indicates that the superconductor will have to withstand fields as high as 12 T. This high value requires that superconducting materials from the A-15 class (Nb3Sn, Nb3Al, V3Ge, etc.) be used, at least in the high-field portions of the magnets.
