Abstract

The Energetic Particles, Acceleration, Composition and Transport (EPACT) Experiment on the WIND spacecraft, and especially its large-geometry Low Energy Matrix Telescope (LEMT), is capable of sensitive measurements of ions of the anomalous cosmic-ray (ACR) component above 2 MeV/amu. We report on the energy spectra of He, C, N, O, Ne, S, and Ar and estimate element abundances at the acceleration site.
