Abstract
Particle accelerators are finding increasing use in the study of materials. This review will concentrate on their application to study radiation damage effects. The first section will deal with the basic interaction of particle beams with solids, the production of defects and their agglomeration, and phenomena such as irradiation-enhanced diffusion and precipitation. The second part of the review complements the recent Contemporary Physics article by J. R. Matthews (1977) which deals with the behaviour of materials in fast reactors. It discusses in some detail the application of particle accelerators to technological problems such as void formation in fast reactor materials and irradiation enhanced creep.
