| Research Abstract |
In recent years, the research and development on the applications of REBCO superconducting coil to the high field magnets (e.g. accelerator, NMR, and MRI) attract considerable attention. In REBCO coil, large screening currents are induced in the winding tape by the radial component of the magnetic field. As a result, the irregular field generated by the screening currents affects the high-accuracy magnetic field distribution spatially and temporally. In this study, we developed a novel numerical simulation based on the finite element method, boundary integral equation, and fast multipole method. And, we numerically and experimentally evaluated the irregular field generated by screening currents in REBCO coil. We clarify the effect of the screening currents on the magnetic field distribution.
This work contributes to the design of high temperature superconducting magnet with reduction of field generated by screening current, the homogeneity and temporal stability of field.
