Design of a 3T Superconducting Dipole Magnet

In this article, we presented a technical design of the superconducting Dipole magnet, H-type like the SAMURAI magnet at RIKEN, for the Lithium(Li) alloy, the material of first wall of ITER Demo, magneto fluid behave study, depending on mechanics, thermal and electromagnetic multi-field couple analyze results. The operating current and the goal of central field are 425 A and 3.0 T within 1000 mm × 1000 mm × 300 mm (L × W × H) region. In order to limit the temperature, current and voltage values under a reasonable value in case of a quench, multi-segments protection method was employed. The magnet is under construction and the test results will be reported.
