- Physically part of the 3DA instrument, The Energetic Particle Instrument (EPI)
on EQUATOR-S consists of an array of solid-state telescopes measuring electrons
and ions in the energy range 20 - 226 keV and 20 - 400 keV, respectively, in 6
energy channels and 4 angle channels at a time. During each spacecraft spin the
telescopes trace out a large fraction (70%) of the solid-angle sphere.
