Analysis of JUNO-observed Pitch Angle Spectra of heavy Ions in Jupiter’s Middle Magnetosphere — •Michael Schöffel1, Joachim Saur1, Barry Mauk2, and George Clark21Institut für Geophysik und Meteorologie, Universität zu Köln, Köln, Deutschland — 2Applied Physics Laboratory, The Johns Hopkins University , Laurel, Maryland, USA

Here we analyze He, S, O and H ions measured by the JEDI instrument in the energy range from (60 to 1350) keV, (486 to 10.000) keV, (370 to 10.000) keV and (30 to 2600) keV, respectively, at rotational equator crossing distances to Jupiter between 30 - 100 RJ. We study how the energy and pitch angle spectra of these ions change inside and outside the current sheet and look at their radial and latitudinal dependency. A prime objective is to investigate the energization mechanism of the heavy ions observed in the middle magnetosphere that heats up ions to much higher temperatures than expected for an adiabatic process. We further use the JUNO data to estimate the thickness of Jupiter’s current sheet.
