Facility Details

Atom-probe tomography (APT) is a microanalytical method producing an atom-by-atom three-dimensional reconstruction of the sample studied with sub-nanometer resolution. NUCAPT operates a LEAP3000XSi (Imago Scientific Instruments). Voltage and laser assisted field-evaporation allow the analysis of a broad spectrum of materials. The typical analyzed volume is about 150x150x500 nm^3. APT is particularly suitable to study nano-structured materials. Specimen preparation of almost any material is possible by FIB.
