TAPSim is a simulation package which has been developed to better understand the effects which arise in  APT measurements of samples with heterogenous evaporation properties. It allows the theoretical analysis of tips with arbitrary shape, with arbitrary atomic structure and well-defined chemical composition. In this regard, practically no limitations exist. Each tip atom is represented by a Wigner-Seitz cell.

The produced output by the simulation can be analysed with standard APT analysis techniques as they are applied to real experimental data, too. For this reason TAPSim enables a one on one comparison with a theoretical model of a sample and with direct measurements. From a theoretical point of view it offers the possibility for testing new concepts and procedures for APT data treatment in a reliable and controlled way. Hopefully, this  approach helps to improve the quality of the 3D reconstruction procedures as well as it will readily help to reveal and understand artifacts in present reconstructions of the measurement data.
