Abstract :
For the Hermes project, a radiation pre-screening program was carried out on nine types of R3000/R3000A RISC microprocessors and four types of R3010A co-processors. Results from this program which cover Single Event Upset/Latch-up (SEU/SEL) testing using Cf-252, heavy ion and proton simulation sources, and total ionising dose testing using a Co-60 source, are presented. Expected in-orbit upset rates, based on the SEU ground test data and the CREME suite of programs, are calculated for two Hermes orbits, 460 km/28.5 degrees and 450 km/64.8 degrees .
