    "abstract": "We extend a recently introduced mapping model, which explains the bunching\nphenomenon in an ion beam resonator for two ions [Geyer, Tannor, J. Phys. B 37\n(2004) 73], to describe the dynamics of the whole ion bunch. We calculate the\ntime delay of the ions from a model of the bunch geometry and find that the\nbunch takes on a spherical form at the turning points in the electrostatic\nmirrors. From this condition we derive how the observed bunch length depends on\nthe experimental parameters. We give an interpretation of the criteria for the\nexistence of the bunch, which were derived from the experimental observations\nby Pedersen et al [Pedersen etal, Phys. Rev. A 65 042704].",
