| Abstract Scope |
Atom Probe Tomography (3D imaging mass spectrometer) is the highest sensitivity analytical method identifying up to 80% of the atoms in a volume with sub-nanometer spatial resolution. The time-of-flight mass spectrometer has sufficient mass resolving power to identify individual isotopes of all masses from hydrogen to uranium and beyond with nominally equal sensitivity. Achieving this performance requires specialized specimen preparation, ultra-high vacuum, high-speed pulsing and timing electronics, as well as specialized data reduction techniques. Installations in France and the US have included modifications to facilitate the handling of radioactive materials with the mindset of time, distance, and, shielding.
Over the 50 years since atom probe tomography was first demonstrated the technique has been developed to be fast and easy to use. This poster will summarize the technology and methods to achieve such performance with a focus on the contributions that APT has made for nuclear materials. |
