Results from Juno's Radiation Monitoring Investigation
Abstract
Juno's Radiation Monitoring (RM) Investigation measures the high-energy particle environment at Jupiter by making use of noise signals from penetrating high-energy particles as an in situ observable. The implementation approach was born out of knowledge gained during the development of Juno's instruments and spacecraft which must withstand the incredibly harsh radiation environment at Jupiter. Images and housekeeping data from several of Juno's heavily shielded instruments are actively planned, retrieved, and analyzed to extract the characteristic signatures of penetrating high-energy electrons and ions during each of Juno's science orbits. Collaborative observation campaigns are performed to simultaneously collect "radiation images" and penetrating particle counts from multiple instruments in previously unexplored regions of the magnetosphere [Becker, H.N., et al.

This presentation will provide a summary overview of the Investigation's key findings since Juno's arrival at Jupiter in 2016.
