Abstract

A statistical analysis comparing the number of CREME-96 worst-week environments [1] to a space environment particle flux data analysis and the PSYCHIC model [2] is presented. This analysis provides an indication of the number of worst-week environments that are required to obtain a particular confidence level and determine the associated risk of a destructive single event effect over a mission. A direct assessment of SEE rate specific for components and shielding geometries using the ESA SEPEM system [3] is also presented.
