Abstract
Field ion microscope has been used to investigate argon ion bombardment of tungsten at 63 K. The bombardment was carried out at a background pressure in the 10^-11 torr range with 400 eV Ar^+ ions. Clusters of vacancies and interstitials have been observed. After field evaporation of a few atomic layers damage could still be observed on the newly exp0sed surface indicating damage produced inside the specimen. Evidence for an assisted focusing event in the direction of the [100] - zone is presented.
