Field distributions of the ANKE dipole magnets have been calculated numerically. Results for the stray field at the polarized atomic beam source and the storage cell gas target in COSY-Juelich are presented. The necessary soft-iron shields around the rf-transition units of the atomic beam source are discussed. Furthermore, a dependence of the focussing properties of adjacent permanent sextupole magnets on their relative azimuthal orientation and on the deviation from co-axiality has been investigated.
