Abstract
The classical dynamics of a single ion, trapped in a Penning trap perturbed by a octupolar electrostatic perturbation, was investigated. The Penning trap provided three-dimensional trapping of charged particles by means of a magnetic field plus a quadropolar electric field. Analysis showed that the effect of the octupolar perturbation was to create four equivalent channels of escape through which the ion was able to leave the trap.
