[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide a T-level high-field superconducting magnet system for space propulsion and ground simulation environment. The electromagnet resistance and magnetic circuit loss of the existing technology are large, the magnetization characteristics of the magnetic iron core have a saturation limit and the magnetic iron core is too heavy, it is difficult to generate a stable strong magnetic field in a wide range, and increasing the number of coil turns will increase the volume and weight At the same time, it is also impossible to efficiently form a strong magnetic field in a small space. It is required that a new technology superconducting magnet applied to the space propulsion ground simulation environment should be able to resist high temperature thermal load requirements, and at the same time protect high-energy particle sputtering technical issues
