Use of Proton SEE Data as a Proxy for Bounding Heavy-Ion SEE Susceptibility

We examine use of proton single-event effect (SEE) data to constrain heavy-ion SEE susceptibility. We discuss limitations due to short-range proton recoils, especially for destructive SEE modes. We develop an equivalent linear energy transfer metric that reduces risk that proton data will significantly underestimate SEE susceptibility and suggest a probabilistic model for using proton data to constrain device-sensitive volumes.
