  skos:definition """The Electron, Proton, and Alpha Monitor (EPAM) on the Advanced
Composition Explorer (ACE) 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 cm2 sr), two Low Energy Magnetic Spectrometers (LEMS)
measure the flux and direction of ions greater than 50 keV (geometry
factor = 0.48 cm2 sr), and the Composition Aperture (CA) measures the
elemental composition of the ions (geometry factor = 0.24 cm2 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.

EPAM was designed and developed by ther Johns Hopkins Applied Physics
Laboratory.
