The Solar Electron and Proton Telescope (SEPT) onboard the twin STEREO spacecraft will detect electrons from 35 to 485 keV, and protons from 75~keV to 7 MeV. There are two sensors per spacecraft. Each sensor unit consists of a dual double-ended magnet/foil solid state detector particle telescope. This technique allows to separately measure electrons and ions in the energy ranges given above. One of the major scientific goals of the STEREO mission is the investigation of particle acceleration and propagation from the Sun to the Earth. Electrons, as measured by the SEPT, play a crucial role in the study of energetic processes on the Sun as they provide a direct link to the sites of particle acceleration. The semiconductor detectors of SEPT are currently saved against Sun illumination by titanium doors which will be opened after the last spacecraft manoeuvre in January 2007. In this contribution we will report on the first SEPT measurements.
