Base class for collecting a run with a real or a simulated atom probe or field-ion microscope.

The term run is understood as an exact synonym for session, i.e. the usage of a real or simulated tomograph or microscope for a certain amount of time during which one characterizes a single specimen.

Research workflows for experiments and simulations of atom probe and related field-evaporation evolve continuously and become increasingly connected with other methods used for material characterization specifically electron microscopy. A few examples in this direction are:

The majority of atom probe research is performed using the so-called Local Electrode Atom Probe (LEAP) instruments from AMETEK/Cameca. In addition, several research groups have built their own instruments and shared different aspects of the technical specifications and approaches including how these groups apply data processing e.g.:

to name but a few.
