The LET spectrum and its uncertainty during the CRRES mission
Abstract
We present LET spectra calculated for the 1990-1991 CRRES mission using the galactic cosmic ray (GCR) and solar energetic particle (SEP) models which were developed for the CRRES/SPACERAD program. We discuss the dependence of the spectra on uncertainties in the galactic cosmic ray and solar energetic particle models and LET calculation methods. Finally, we illustrate the application and significance of these spectra by using them to predict single event upset rates in a sample integrated circuit memory device, a 256 x 4-bit bipolar static RAM device.
