The SSC (Superconducting Super Collider) magnets feature grouped ends in which cables of a particular coil remain stacked together as they are bent around the end. Methods have been developed to form the ends in such a way that mechanical stresses are lowered and field quality is optimized. The authors discuss techniques of end turn design and present calculations of harmonics and peak fields for the SSC quadrupole QSE101. By optimizing the end configuration, integrated harmonics through the end have been minimized.
