ACE Electron Proton Alpha Monitor

ResourceID
spase://SMWG/Instrument/ACE/EPAM

Description

EPAM is composed of five telescope apertures of three different types.
Two Low Energy Foil Spectrometers (LEFS) measure the flux and direction of electrons above 30 keV (geometry factor = 0.397 cm^2 sr),
two Low Energy Magnetic Spectrometers (LEMS) measure the flux and direction of ions greater than 50 keV (geometry factor = 0.48 cm^2 sr),
and the Composition Aperture (CA) measures the elemental composition of the ions (geometry factor = 0.24 cm^2 sr).
The telescopes use the spin of the spacecraft to sweep the full sky. Solid-state detectors are used to measure the energy and composition of the incoming particles.
