AbstraktAbstract

The compact light weight SATRAM payload, which is based on the hybrid semiconductor pixel detector Timepix, is operating in open space onboard ESA’s Proba-V satellite in low Earth orbit since 7th May 2013. The Timepix chip can determine the composition and spectral characteristics of ionizing radiation in the satellite environment. The device provides single quantum X-ray photon and charged particle counting for high sensitivity detection, high resolution tracking and directional visualization of energetic charged particles over a wide dynamic range of particle fluxes, energies and broad field of view. The motivation for this work and short description of the detector is given together with first results of its response in open space. Preliminary results on particle/dose rate in spatial and time correlated maps along the satellite orbit are presented.
