Design of Coil Ends for Superconducting Magnets Applying Differential Geometry Methods

摘要

An integrated design process has been adopted at CERN for the design of superconducting magnets, with the ROXIE program package as the key tool. Besides the essential tasks of determining optimal coil and yoke shapes in the cross-section, the adequate layout of the coil ends has proven to be the limiting factor for the magnets' quench performance. The objectives are to minimize mechanical stress on the cables, to optimize the multipole content of the integrated field and to limit the peak field enhancement. This paper introduces a new approach based on differential geometry methods for the ROXIE coil end routine that allows for the geometrical optimization of coil ends in the framework of the integrated magnet design.
