The AE-9 Trapped Electron Model Radiation Environment and Effects on Electronics for Several Shielding Configurations

摘要

At the 2017 ICES conference in Charleston, SC, we presented space radiation effects data on electronics under certain shielding configurations on spacecraft residing in a geostationary orbit (6.6 RE) using the old AE-8 trapped electron model 1 . In this paper we re- examine the geostationary space radiation environment, which consists of high-energy (8-10 MeV) electrons and low-fluence, low-energy protons using the recently released AE/AP-9 models and compare the earlier results that used the AE-8 trapped electron model. In addition, we also include the galactic cosmic radiation (GCR) and possible solar proton event (SPE) effects. The results of a parametric study of the trapped, GCR, and SPE radiation environments on electronics for a number of shielding configurations using a variety of shielding materials are discussed in detail.
