1-D Physical Model of Charge Distribution and Transport in Dielectric Materials Under Space Radiations

In this paper, the development of a 1-D physical and numerical model is presented for the description of charge transport and ionization processes of irradiated space used polymers (Teflon FEP and Kapton HN). This model extends the previous circuit model described by Hanna et al. and relies on solid...

Summary:In this paper, the development of a 1-D physical and numerical model is presented for the description of charge transport and ionization processes of irradiated space used polymers (Teflon FEP and Kapton HN). This model extends the previous circuit model described by Hanna et al. and relies on solid-state physics. This model aims at predicting the charging behavior of space used dielectric materials under space radiation conditions. A physical validation is carried out through crossed comparisons with the experimental data on surface potentials, conductivity and bulk charge distribution. For this physical validation, different irradiation conditions and several materials are presented. The interest of this 1-D model is to obtain a more realistic prediction of dielectric charging behavior as a function of time as well as a better bulk charge description.
