Solar Orbiter is a mission proposed to ESA for the cosmic vision program. It will provide the next major step forward in the exploration of the sun and the heliosphere to investigate many of the fundamental problems remaining in solar and heliospheric science. Onboard, the Energetic Particle Detector (EPD) will measure the composition, time history and distribution functions of suprathermal and energetic particles. The EPD consists of five separate sensors. One of them is the Electron Proton Telescope (EPT), which is designed to measure electrons within the energy range from 20 keV to 400 keV and protons from 20 keV to 6 MeV. Low energy electrons and nucleons stopping in the first detector are distinguished by using the foil/magnet-technique. In this contribution first measurement of the Prototype with radioactive sources and its functionality will be presented.
