September Tool of the Month: Cameca 3D Atom Probe

The tool of the month for September is the Atom Probe Tomography (APT) system. Users at the CNS have access to the Cameca LEAP 4000X HR. This tool provides researchers provides nano-scale surface, bulk and interfacial materials analysis of simple and complex structures with single atomic identification and accurate spatial positioning. 
The system works by systematically evaporating a needle-shaped prepared sample, either by directly ionization using a focused UV laser or a strong electric field applied to the sample. The evaporated ions travel to a detector which provides compositional information of the sample in a 3D image.

For more information, see the Cameca website page on APT or contact to Andrew Magyar.
