rt of the performance optimization lies in the description and correction of the aberrations associated with the spectrograph and its ion optics. The ion optics of the SE-SPS to fifth order have been simu\
lated using the code COSY, and have been applied to a Monte-Carlo kinematics simulation of a generic transfer reaction in the target chamber to simulate the trajectories of particles from the reaction poi\
nt to the focal plane. The simulation can be inverted to correct for the leading aberrations by applying tracking information obtained in the focal plane detector. The ion optics and the performance chara\
cteristics of the SE-SPS will be presented, and examples of aberration corrections on experimental data will be given.
