The EPACT experiment will measure abundances, spectra, and angular distributions of particles from 20 keV/amu to 500 MeV/amu. At high energies, isotopes will be resolved up through Z = 26, at intermediate energies elements with Z between 1 and 82 will be observed, and at low energies element abundances above Z = 2 will be resolved for the first time.
The Energetic Particle: Acceleration, Composition and Transport (EPACT) experiment for the WIND spacecraft to be launched in late 1992 is presented. This experiment is designed to study the acceleration, composition and transport of a wide variety of energetic particle populations, including particles accelerated in interplanetary shocks, particles from solar flares, the anomalous component, and the Galactic cosmic rays.
Scientific studies of energetic particle populations observed by STEP are summarized. Science highlights cover: upstream He-3 events general upstream events, energy spectra of ions accelerated in impulsive and gradual solar events, impulsive solar particle events, and corotating interaction regions. Bibliographies of journal publications and papers presented at conferences are also provided.
