Electrostatic Reconstruction Technology in Atom Probe Tomography

In atom probe tomography (APT) a primary element of the instrument optics is the specimen itself. In order to correct artifacts in the data caused by an evolving apex shape, we are developing a numerical electrostatic model [1, 2] reflecting the physics of both the instrumental pieces as well as the specimen geometry. In this poster we report on some numerical accuracy metrics of this model and illustrate its use in the generation of simulated evaporation data.
