Proposal of a Multiscale High Accuracy Engineering Approach for Single-Event Effects Analysis in Modern Technologies

Standard heavy-ion single-event rate estimation methods are well adapted to mature technologies used in the space industry. However, the adoption of 3-D structures as well as advanced technology nodes may reduce the confidence in established rate estimation methods such as integral rectangular parallelepiped (IRPP). In this work, a single-event effect (SEE) rate calculation method with a GEANT4-based Monte Carlo (MC) approach was designed in order to address this shortcoming. It is intended as an extension to the IRPP method in the context of advanced technologies in the space industry. This article presents the general concepts and theory behind this approach, as well as results from validation cases based on flight data.
