Scientific paper

Jupiter’s immense magnetotail was uniquely traversed and observed in situ to 2562 Jovian radii for the first time by the Pluto-bound New Horizons spacecraft during the first half of 2007. We show evidence that energetic ions with sulfur-rich composition traceable to Io’s volcanism originated ~150 Jovian radii anti-sunward of the planet and were recurrently released and funneled by the magnetic field down the magnetotail. Ions detected at New Horizons by the Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) instrument showed unmistakable signatures of velocity dispersion. We performed a survey of the unambiguous dispersion events observed by PEPSSI and provide a quantitative description of each event’s dispersion characteristics. Energetic ions are sensitive probes of the magnetic field structure in the magnetotail so, for a case study of one of the most interesting events, beginning on day-of-year 118, 28 April 2007, we are also able to estimate small-scale features of the magnetotail. Our observations (which include energies above ~2 keV/nuc and total energies below ~1 MeV), combined with straightforward simulations of particle flow, are consistent with narrow spatial structures, or filaments, on the order of 5 Jovian radii wide.
