Optimization of coil configuration in a superconducting dipole magnet for compact synchrotron light source

Compact electron storage rings with strongly curved superconducting dipole magnets have been studied as a potential soft X-ray source for the production of ultra-large-scale integrated circuits. The authors describe a numerical method based on linear programming and two-dimensional field calculations by the finite element method to determine the coil configuration in such a dipole magnet. The usefulness of this method is demonstrated in connection with designing a magnet having the smallest possible magnetomotive force and a good field region of a required size for given design parameters such as maximum dipole field strength or bending radius
