Abstract

This paper presents racetrack High Temperature Superconducting (HTS) magnet with iron plates to achieve the maximum current-carrying capacity and the simple shape that can easily be wound and jointed. On the basis of the magnetic field analysis using Biot-Savart's law and 3 Dimensional Finite Element Analysis (3D FEA), this study is focused on the function of iron plates, which is to obtain smaller B${\perp}$, and stress and strain condition of Ag-sheathed Bi-2223 37-filament HTS tapes are considered. Moreover, the measured performance of the magnet with iron plates improved by 50% on the basis of initial magnet.
