Evidence for local acceleration of heavy >10 MeV/n oxygen and sulphur in Jupiter's innermost radiation belts

Jupiter's radiation belts constitute a multi-component system, trapping high intensities of electrons, protons and heavier ions. We revisit measurements from Galileo's Heavy Ion Counter (HIC) instrument, a high-quality dataset that extends considerably the energy range covered by Galileo/EPD and Juno/JEDI (
