Quantitative Laser Testing for Predicting Heavy-Ion SEE Response—Part 1: Metrics for Assessing Response Agreement

A series of distance metrics to quantitatively assess the level agreement between laser- and ion-induced single-event effects are presented. Historically, this agreement has been assessed by visual inspection. While traditionally effective, this approach can lead to misleading comparisons and erroneous conclusions. To enable quantitative comparisons for response agreement, a more objective approach is required. The present work defines and demonstrates the use of five distinct distance metrics to quantitatively assess the level of single-event effect (SEE) response agreement. These metrics correspond to each of the five categories in which most of the published SEE work can be sorted. Various applications of these metrics are shown, including the objective correlation of laser pulse energy (PE) and ion linear energy transfer (LET). While demonstrated with laser and ion data, this approach can be applied to other surrogates for heavy-ion testing and may be used to validate results obtained from potential predictive surrogate testing techniques.
