The “two-step” magnet design strategy is proposed based on the “divide and conquer strategy”, which is robust, efficient and simple in logic. With this strategy, the design process of a large number of magnet blocks is decomposed into independent designs of each magnet block, and then iterates to find the solution, thus the specific form of each magnet block can be regularly customized and the magnets suitable for the engineering implementation can be easily designed.
This strategy gives almost the same magnet design as the Fourier decomposition method, which validates the practicability of this strategy and lay a solid foundation for the subsequent design of standardized magnet. (LU Zhiyuan reports)
