LASP provided the Relativistic Electron Proton Telescope (REPT) instrument as part of the Energetic Particle, Composition, and Thermal Plasma (ECT) Suite on the Van Allen Probes. This suite directly measures near-Earth space radiation particles to understand the physical processes that control the acceleration, global distribution, and variability of radiation belt electrons and ions. REPT covers the challenging electron range of 4-10 MeV and proton energy range of 20-75 MeV to capture most intense events.
