Jupiter Energetic Particle Detector Instrument (JEDI)

NSSDCA ID: 2011-040A-06

Mission Name: Juno
Principal Investigator:Dr. Barry H. Mauk


Jupiter Energetic Particle Detector Instrument (JEDI) was designed to characterize the polar magnetosphere of Jupiter by measuring the pitch angle and energy distribution of high-energy particles electrons across auroral features. Consisting of three identical detectors, JEDI can detect electrons between 25 and 800 keV and hydrogen and oxygen from 10 keV to 8000 keV.
