Investigation of the high energy tail of Jovian radiation belts using Juno background data
Abstract
One of the main science objectives of the Juno mission aims to study the Jovian polar magnetosphere using a combination of science instruments with sensitivity to electrons and ions up to 1 MeV. We propose to utilize the background data from the Ultraviolet Spectrograph (UVS), the Jupiter Energetic-particle Detector Instrument (JEDI), and the Jovian Auroral Distributions Experiment (JADE) aboard Juno to study the dynamics of energetic electrons above 1 MeV. For example, it has been characterized that "Bar Code" events in the UVS data is a signature of ~10 MeV electrons [Bonford, GRL, 2018]. It is also thought that noise background data from JEDI and JADE might be a signature of penetrating high-energy electrons. Characterization of energetic electrons above 1 MeV is a critical aspect of reducing uncertainties in the Jovian radiation models, assisting in the understanding Juno data as well as impacting the design of future missions to Jupiter. Initial simulation and analysis show correlation between high energy electrons and background data from the Juno scientific instruments. Preliminary results of the analysis and comparisons with the Galileo Interim Radiation Electron (GIRE3) model will be presented.
