In-Flight Measurements of Radiation Environment on Board the Argentinean Satellite SAC-D

Measurements of the ICARE-NG/CARMEN-1 (Influence sur les Composants Avancés des Radiations de l’Espace-Nouvelle Génération/CARactérisatin et Modélisation de l’Environnement spatial) detector on board the low Earth orbit Argentinean satellite SAC-D are presented. Particle fluxes are obtained for electrons from 250 keV up to 3.2 MeV and protons from 12.8 MeV up to 190 MeV since September 2011. As the detector was placed on a side of the satellite which is directed45^∘from zenith, large anisotropy was observed in the measurements. Finally, making advantage of the 128 different channels, a singular value decomposition (SVD) method was used to reconstruct with a great precision the proton spectrum in the range 60-300 MeV, and extended it up to 600 MeV.
