The 10-cm Atom Probe, invented in 1973 by J. A. Panitz [9] was a “new and simple atom probe which permits rapid, in depth species identification or the more usual atom-by atom analysis provided by its predecessors ... in an instrument having a volume of less than two liters in which tip movement is unnecessary and the problems of evaporation ...
George David William Smith FRS, FIMMM, FInstP, FRSC, CEng (b. 1943, in Aldershot, Hampshire) is a materials scientist with special interest in the study of the microstructure, composition and properties of engineering materials at the atomic level. He invented, together with Alfred Cerezo and Terry Godfrey, the Atom-Probe Tomograph in 1988.
Tomography is imaging by sections or sectioning that uses any kind of penetrating wave. The method is used in radiology , archaeology , biology , atmospheric science , geophysics , oceanography , plasma physics , materials science , cosmochemistry , astrophysics , quantum information , and other areas of science .
High angle ADF STEM is a particularly useful imaging mode for electron tomography because the intensity of high angle ADF-STEM images varies only with the projected mass-thickness of the sample, and the atomic number of atoms in the sample. This yields highly interpretable three dimensional reconstructions. [32]
Imago (name comes from the Latin word for image or picture) has not only improved the instrumentation available for atom probe tomography, but has also developed many sample preparation techniques that are key enablers for the 3D sub-nanometer compositional information that the microscope provides.

The electron microprobe (electron probe microanalyzer) developed from two technologies: electron microscopy — using a focused high energy electron beam to impact a target material, and X-ray spectroscopy — identification of the photons scattered from the electron beam impact, with the energy/wavelength of the photons characteristic of the atoms excited by the incident electrons.
A team of U.S investigators was being assembled to aid South Korea's probe into the crash. The crash happened the same week an Azerbaijan Airlines flight crashed in Kazakhstan, killing 38 people.
