The spatial and time characterisation of trapped charged particle trajectories in magnetospheres has been extensively studied using dipole magnetic field structures. Such studies have allowed the calculation of spatial quantities such as equatorial loss cone size as a function of radial distance, the location of the mirror points along particular field lines (’L shells’) as a function of the particle’s equatorial pitch angle, and time quantities such as the bounce period and drift period as a function of the radial distance and the particle’s pitch angle at the equator. In this study, we present analogous calculations for the ‘disc-like’ field structure associated with the giant rotation-dominated magnetosphere of Jupiter as described by the UCL/Achilleos-Guio-Arridge (UCL/AGA) magnetodisc model. We discuss the effect of the magnetodisc field on various particle parameters, and make a comparison with the analogous motion in a dipole field.
