The deposition of energy lost by a fast ionic projectile in the target leads to the ejection of material in the form of atoms or clusters ("sputtering"). The measurements of yields, energy and angular distributions of sputtered particles contribute to the understanding of the initial microscopic processes of damage and defect creation in materials. A new UHV system (AODO) allows measuring the mass distributions and the velocity vectors of each emitted secondary ion by means of time-of-flight and imaging techniques XY-TOF-SIMS ("Secondary Ion Mass Spectroscopy") with well prepared target surfaces. Here, we focus on the sputtering of lithium fluoride (an ionic crystal, a large band gap insulator ≈ 14 eV) by fast heavy ions (≈ 10 MeV/u). As a ...
