FairRoot/CbmRoot Simulation and Analysis framework

The Virtual Monte Carlo concept allows performing simulations using Geant3, Geant4 or Fluka without changing the user code [1]. This concept was used as a base for developing the CbmRoot framework for the CBM collaboration [2]. In this concept, the same framework is used for simulation and data analysis. An Oracle database with a build-in versioning management is used to efficiently store the detector geometry, materials and parameters. As more experiments at the GSI where interested in using this framework, the framework was revised and the base packages of the framework where completely separated from the specific CBM implementation. Moreover, the framework became the new name FAIRROOT. On the Oracle server side, data bases for each experiment are running on a high availability cluster, new experiments can easily be added. The Schematic design of the framework is shown in Fig.[1].
