Modeling and electromagnetic optimization based on combined optimization method for solenoid superconducting magnet

Focusing on the design of the solenoid superconducting magnet which is extensively applied in many superconducting systems, this paper proposed a novel optimization method which comprehensively takes the energy, the stray field and the volume of the magnet into consideration. The electromagnetic model of the multi-solenoid superconducting magnet for the optimization is worked out based on the magnetic field calculation for the single solenoid magnet, and the stray field and the maximum fields of the multiple parallel solenoids are calculated with the method of vector superposition. Combining with global search and traditional mathematic programming, the established model is optimized. The results show that the satisfactory electromagnetic optimization design of the solenoid superconducting magnet can be obtained using the proposed method.
