The ERNE instrument measures energetic ion fluxes covering elements from hydrogen to zinc with isotopic resolution up to neon (LED) or beyond (HED). The energy range covers about two orders of magnitude for each ion species being 1.5 - 110 MeV/n for protons and alphas, 3-300 MeV/n for CNO, and 4-600 MeV/n for iron. The geometric factor of the instrument is large: 0.26-0.92 cm² sr for LED and 25-40 cm² sr for HED depending on particle energy.
