Abstract
Disclosed is a method for designing a superconducting magnet for generating high magnetic fields with high uniformity for controlling a stray field to be within an allowable range and acquiring structural and magnetic stability by optimizing the arrangement of positions and shapes of coils configuring the superconducting magnet. Volumes of a main coil and a shielding coil are set to be variables, and the critical value of a wires related on the current and magnetic field, the heat transfer depth, and the quench strain are defined to be restriction conditions so that linear programming is applied to determine an initial shape of the shielding coil and division of the main coil based on the sum of total volumes, that is, an objective function. The initial shapes of the main coil and the shielding coil determined through the linear programming are revised and the shape of a shimming coil is determined by using non-linear programming based on the objective function.
