Designer´s Guide to Radiation Effects on Materials for Use on Jupiter Fly-Bys and Orbiters

This paper summarizes the state-of-the-art of the complex field of radiation effects on spacecraft materials. It is intended as a guide for designers of systems exposed to damaging electrons and protons. The emphasis is on the relative damage levels for the more common materials that may be used. Information on the preliminary flux and fluence levels of the yet to be designed Jupiter orbiter, Galileo, is also presented.
