Abstract
Symplectic mappings that describe the 3D betatronic motion in a magnet ic lattice are considered. We define the dynamic aperture in terms of the connected volume in phase space of initial conditions that are bou nded for a given number of iterations. Different methods for a fast es timate of this quantity are given; the analysis of the associated erro rs and the optimization of the integration steps are outlined. A compa rison of the accuracy of these methods is given for both simple models and more realistic lattices.
