Cosmic radiation environment modelling for the ESEO mission

Abstract

The development of the European Student Earth Orbiter (ESEO) was announced by the European Space Agency Education Office for students interested in the space exploration. The ESEO-TRITEL Team, supported by the Centre for Energy Research, Hungarian Academy of Sciences, joined this international cooperation by the development of the ESEO satellite version of the TRITEL 3D silicon detector telescope. Previous version of the TRITEL detector has been already operated successfully on board the European Columbus module of the International Space Station (ISS) and another version was installed in the Russian segment of the ISS as well. In the ESEO-TRITEL experiment the anisotropies in the radiation field, the effects of the Earth shadow and the South Atlantic Anomaly (SAA) will be analyzed. The results will be compared with the fluxes calculated with the new AP-9 and AE-9 trapped proton and electron models, and possibly also compared against the previous AP-8 and AE-8 models for exploring differences. In this work the space radiation environment was reconstructed for the ESEO mission with the different models and the new results were compared to the ones obtained from the older model.
