Particle Environment Package (PEP) is a suite of six sensors, four of which are dedicated to ion and electron measurements covering an energy range spanning more than nine orders of magnitude, from 1 eV to 5 MeV. All four charged-particle PEP sensors operated during the JUICE Lunar–Earth Gravity Assist (LEGA) maneuver for 8 days in August 2024 and sampled all major domains and boundaries of the terrestrial magnetosphere, including the ring current, radiation belts, plasmasphere, magnetosheath, magnetopause, bow shock, foreshock, and solar wind.
We present a unique combined snapshot of the entire magnetosphere and identify specific particle populations observed across different energy ranges, including cold plasmaspheric ions, freshly injected ring-current ions, auroral-accelerated electrons, and trapped radiation-belt populations. This overview clearly demonstrates the power of the multi-sensor PEP suite for magnetospheric studies.
We also extrapolate these observations to the anticipated measurements when JUICE will be flying through the Jovian magnetosphere.
