The ALICE Simulation Framework

Ivana Hrivnacova, Andreas Morsch
 CERN For the ALICE Offline Group

Speaker: Andreas Morsch

  ALICE uses an object-oriented framework for simulation and reconstruction (AliRoot) based on ROOT. Here, we describe those components of the class design that represent common concepts of simulation such as particle generation and transport, detector response and detector segmentation. The smooth way of transition from existing Geant3 simulation software to Geant4 adopted by ALICE is explained. As a client of the Monte Carlo interface (pure abstract class) AliRoot is used both for Geant3 and Geant4 simulations. Applications for fast and slow physics and detector performance simulations as well as the relevance of the design for visualisation and the link of simulation to reconstruction are discussed.
