The Juno Jovian Auroral Distributions Experiment (JADE)

The Jovian Auroral Distributions Experiment (JADE) is a part of the suite of instruments carried on Juno to directly explore, for the first time, Jupiter's polar magnetosphere in general and auroral processes, in particular. JADE comprises a single-head ion mass spectrometer (JADE-I) and three identical electron energy per charge (E/q) analyzers (JADE-E) to measure the full auroral electron and ion particle distributions. Together these three-dimensional distributions 1) determine the particle populations that precipitate into the auroral regions and produce the observed auroral emissions; 2) measure the leakage of Jovian ions out along the field; and 3) address the acceleration processes at work in the regions both around and below the spacecraft. This paper briefly summarizes the JADE scientific objectives, instrumentation, and capabilities.
