OPTIMIZING THE CONDUCTOR DIMENSIONS FOR A 10-13 T SUPERCONDUCTING DIPOLE MAGNET

Most of the dipole magnet design studies are focused on the quality of the dipole field. However, to be of practical interest certain requirements have to be considered. For instance, to facilitate the winding of the coil end part, the top angle of the inner layer of the coils should be limited and the cable used for this layer has to be kept thin. An essential requirement is also that the peak field in a coil layer must not exceed the maximum field of the superconductor as a function of the current density. In this paper a method is described to design the conductor dimensions and lay-out for high field dipole magnets subject to a number of requirements and using a measured J(max)(B) relation for the superconductor.
