SAE International announces a new technical standard that provides an example process for analyzing neutron Single Event Effects (SEE) for an electronic-based airborne system for use in system safety assessments.

“AIR6219 – Incorporation of Atmospheric Neutron Single Event Effects Analysis into Safety Assessment” describes an example process to evaluate the effects of atmospheric radiation at the equipment level, based on effects on electronic circuits.

Galactic cosmic rays and solar rays penetrate the earth’s atmosphere and produce particle cascades. The atmospheric radiation is comprised mainly of high energy neutrons that can interact with a semiconductor device’s silicon structure causing adverse behavior. This document primarily covers neutron effects, as they have the greatest impact on semiconductor device behavior in the atmospheric radiation environment.
