Design and analysis of the 16T superconducting magnet for CFETR strand test facilities

摘要

A 16 T superconducting magnet is being designed with the aim of testing the Nb3Sn superconducting strands and high temperature superconductors. The superconducting magnet will produce a magnetic field of 16 T at the magnet center with magnetic field homogeneity better than 0.5 % at 180 A for a diameter spherical volume of 50 mm. The combination of the Nb3Sn and NbTi coils were used to manufacture the superconducting magnet. The superconducting magnet consists of four inner Nb3Sn coils and two NbTi coils. All coils are connected in a series with a power supply. This paper presents the magnet design, electromagnetic and mechanical behavior analysis of the superconducting magnet.
