Abstract :
Sorting strategies for superconducting dipoles are discussed, in view of maximizing the dynamic aperture in hadron colliders like the CERN LHC. Quality factors based on the perturbative tools of nonlinear maps and normal forms are evaluated with tracking simulations. The best of them is retained and maximized by an appropriate permutation of the magnets. The effectiveness of the proposed ordering is checked again through tracking. This technique is used to sort the sextupolar errors in a lattice that contains a small number of LHC-like cells
