The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

An experimental approach shall as well be presented, which allowed bringing into evidence the shallow charge trap levels in polymers. A cathodoluminescence technique has also been developed, in MARCEL facility installed at ONERA, for the investigation of optical and electrical properties of materials. This analysis is interesting for the characterization of defects / impurities present in materials. These two test benches are complementary and make it possible to extract physical parameters. The implementation of these parameters in physics models developed at ONERA will allow us to improve our understanding and prediction of charging behaviour and radiation-induced conductivity evolution of these polymers under space conditions.
