2.2.2 spase://SMWG/Instrument/Equator-S/EPI Energetic Particle Instrument (EPI) 2019-05-05T12:34:56Z Physically part of the Three dimensional plasma analyzer (3DA) instrument, EPI 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. The EPI instrument (together with the 3DA instrument) is a derivative of the 3D Plasma and Energetic Particle Instrument on the WIND spacecraft. spase://SMWG/Person/Trevor.R.Sanderson PrincipalInvestigator NSSDC's Master Catalog https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1997-075B-04 Information about the Energetic particle instrument (EPI) experiment on the Equator-S mission.
