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.
