Allpix Squared - A Generic Pixel Detector Simulation Framework — •Spannagel Simon — CERN, Geneva, Switzerland

Allpix Squared is a generic open-source simulation framework for the simulation of silicon pixel detectors. Its goal is to ease the implementation of detailed simulations for both single detectors and more complex setups such as beam telescopes. Predefined detector types can be automatically constructed from simple model files describing the detector parameters.

The simulation chain is arranged with the help of intuitive configuration files and an extensible system of modules, which implement the separate simulation steps such as realistic charge carrier deposition using the Geant4 toolkit or propagation of charge carriers in silicon using a drift-diffusion model. Detailed electric field maps imported from TCAD simulations can be used to precisely model the drift behaviour of charge carriers within the silicon, bringing a new level of realism to the simulation of particle detectors.

This contribution provides an overview of the framework and a selection of different simulation modules, and presents a first comparison with testbeam data.
