An optimal design method for multi-section superconducting magnets using modified simulated annealing

It is important for the efficiency of superconductor utilization to minimize winding volume of superconducting magnets. In order to reduce the winding volume, high-field superconducting magnets are usually subdivided into a number of coaxial coils. In this paper, we propose an optimal design method using a modified Simulated Annealing technique, which is newly developed, to realize the minimum winding volume design for multi-section superconducting magnets. The details of the algorithm and several examples of its application to three-section superconducting magnets are shown.<>
