Abstract :
We present a simplified analytical model that shows how fringe field aberrations depend on a quadrupole magnet aperture. It is found that for a fixed magnet length and focal length the fringe field aberrations are smaller if the magnet aperture is larger (i.e. if the fringes are more extended)
