Description

We will present the impact of IRENE models on the Total Ionizing Dose (TID) [1], on Single Event Effect (SEE) rate [1] and on solar cell degradation [2], with respect to historical models such as AE8max/AP8min, MEOv2 and IGE2006, widely used in the space industry.

OMERE freeware, downloaded by a large amount of people all around the world, was first used to compute spectrum from IRENE and historical models, for different missions, and then used to calculate the induced effects in terms of SEE rate for some components and solar cell degradation for a classical 3G30 cell. For the TID calculation, FASTRAD software was used, allowing to consider a 3D realistic geometry of different units and components.
