Modeling the Electron-Proton Telescope on Solar Orbiter — •Sebastian Boden, Jan Steinhagen, S.R. Kulkarni, Jan Tammen, Robert Elftmann, César Martin, Ali Ravanbaksh, Stephan Böttcher, Lars Seimetz, and Robert F. Wimmer-Schweingruber — Christian-Albrechts-Universität, Kiel

The Electron Proton Telescope (EPT) is one of four sensors in the Energetic Particle Detector suite for Solar Orbiter. It investigates low energy electrons and protons of solar events in an energy range from 20 - 400 keV for electrons and 20 keV - 7 MeV for protons. It distinguishes electrons from protons using a magnet/foil technique with silicon detectors. There will be two EPT units, each with double-barreled telescopes, one looking sunwards/antisunwards and the other north/south.

We set up a Monte Carlo model of EPT using the GEANT4 framework, which we can use to simulate interactions of energetic particles in the sensor. Here we will present simulation results of the energy coverage for different ion species and we will study how it will be possible to distinguish between them.
