description The 9.4-T whole-body MRI superconducting magnet system is under manufacturing in the Institute of Electrical Engineering, Chinese Academy of Sciences (IEE CAS), which is used for the high-resolution imaging on human brain and metabolism. The superconducting magnet system with a warm bore of 800 mm is designed, which has the field homogeneity in a DSV of 400 mm better than 5 ppm after superconducting shimmed. In this paper, the magnet structure and superconducting coils manufacture process are introduced. The progress of wet winding and assembling of the magnet is presented. The optimized superconducting jointing technology is reported. During the coils manufacturing procedure, both the electrical insulation performance and the dimensional precision of the coils are controlled.
