Field ion microscope examination of heavy ion radiation damage in iridium

Abstract

The investigation of heavy ion radiation damage in iridium by field-ion and electron microscopy is discussed. An experimental arrangement is described in which prepared field ion microscope specimens may be bombarded in situ by ions from a heavy ion accelerator. Some early results are described of specimens bombarded with A⁺ and Xe⁺ ions in the 50–100 kev energy range at liquid nitrogen and room temperatures.
