Northwestern University Center for Atom-Probe Tomography

(NUCAPT)

Browse: Tools | Research | People | MRSEC

NUCAPT specializes in high-resolution chemical imaging by three-dimensional atom probe tomography (APT). APT produces a three-dimensional (3D) atom-by-atom chemical image with sub-nanometer spatial resolution of a sample volume typically 100 x 100 x 300 nm^3, by simultaneous high resolution imaging and atom-by-atom time of flight mass spectrometry. APT is particularly suited to study nano- or nanostructured materials.


The VG FIM100 atom-probe field-ion microscope (APFIM) is now on display in Terminal 1 at O'Hare Airport, in the concourse opposite gate B12. It was moved to O'Hare Airport to spend its retirement days among applications of the high-performance structural and areospace materials it helped develop.

NUCAPT had originally donated the VG FIM100 APFIM to Chicago's Museum of Science and Industry where it anchored the exhibition Materials Science at MSI (press kit). The Chicago Tribune ran an article about the exhibition "Materials Science" at the MSI on March 25, 2015.
