IMAGO Local Electrode Atom Probe (LEAP)

Quantitative 3D Compositional Imaging and Analysis with Atomic Resolution

 

Instrument Description: (taken in part from Imago Scientific Instruments)
An atom probe specimen is a small pointed tip (microtip) with a ~100nm radius of curvature. A positive voltage is applied to the specimen causing ionization of the surface atoms. Under an applied voltage pulse or laser pulse, the positive ions are “evaporated” from the surface of the sample. Time-of-flight mass spectrometry identifies individual atoms by their elements or isotopes, while point-projection microscopy identifies where atoms were originally located in the specimen. The LEAP uses the principles of both time-of-flight mass spectroscopy and point-projection microscopy to identify individual elements and to locate them within the bulk of a material and build a 3-D image of sample material.

Bruker D8 Discover with GADDS

The Central Analytical Facility houses a Bruker D8 Discover XRD with GADDS. This unit is equipped with a centric Eulerian cradle and a Vantec 500 area detector. This combination gives the Bruker D8 Discover the capability to handle tasks such as phase identification and quantification, textural and residual stress analysis, single crystal diffraction, determination of particle size, percent crystallinity, and structural identification.
