Abstract
The tomographic atom-probe that was constructed enables three-dimensio nal atomic reconstructions of a small volume of a metallic alloy to be obtained. The specimen to be analysed is prepared in the pat of a sha rply pointed needle. Each species is mass analysed and positions are d etermined with an accuracy of a few tenths of nanometres. 3D images pr ovided by this new generation of instrument are given as an illustrati on of performance.
