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. spase://SMWG/Person/Dennis.Haggerty TechnicalContact spase://SMWG/Person/Robert.E.Gold CoInvestigator Instrument description http://sd-www.jhuapl.edu/ACE/EPAM/ Description of the ACE EPAM instrument design and instrument characteristics, with links to data and other documentation NSSDC's Master Catalog https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=1997-045A-08 Information about the EPAM experiment on the ACE mission.
