Perspectives for provision of high quality space radiation environment data using the Energetic Particle Telescope (EPT)

Models of energetic electrons and protons at low altitudes in space display significant discrepancies. In this paper the possible causes of the observed differences between the most frequently used models are discussed, including instrument-induced data inaccuracy. In parallel, on the basis of simulations and in-beam experimental results, solutions to the instrumentation issues are described focusing on the implementation of these into the Energetic Particle Telescope.
