Multi-scale modeling to investigate the single event effects for space missions

In this work, The Multi-Scale Single Event Phenomena Predictive Platform (MUSCA SEP3) is used to evaluate the SER trends for modern devices in space applications and more specifically the emergent impact induced by the direct ionization of proton for nanometric devices. We discuss the impact and the significance of each modeling layer in SER analyses and issues, specifically the radiative environment characteristics i.e. the spectrum, the direction properties and the space weather dynamics. These results demonstrate the relevance and the requirement of the multi-scale approach for reliability issues.
