Abstract

Abstract: Research and development for the practical application of a medical-use MRI superconducting magnet that requires without liquid helium started as the New Energy and Industrial Technology Development Organization's (NEDO) supported project in fiscal 2016. This project will test produce a halfsize active shield-type 3T REBCO coil and realize high magnetic field homogeneity and stability. To achieve this, issues will be resolved by developing the optimal design method for the coil system, establishing a coil manufacture method, stabilizing the magnetic field, and protecting the coil. We will describe the structure and fabrication conditions of the 3T REBCO coil, calculation results of electromagnetic stress. Cooling system design of this coil is also described.
