ExpertRoot Documentation

ExpertRoot (ER) is a FairRoot-based framework dedicated to the simulation, reconstruction, data acquisition, and analysis of the nuclear physics experiments. Primarily developed for the needs of experiments on fragment separator ACCULLINA-2 at Fleurov Nuclear Research in JINR and experiment EXPERT on fragment separator SUPER-FRS at FAIR in GSI.

Key features:
  • User-defined interactions: reactions and decays.
  • It is possible to take into account energy losses of projectiles in the target and the beam detector components such as ToF scintillators and MWPC stations.
  • Simulation and analysis of cocktail and defocusing beam.
  • Accounting for energy losses in the dead layers of the detector during reconstruction of ejectiles energies by experimental data.
Services:

Library Stack

Simulation, reconstruction and analysis in the ER is based on
  • FairSoft - includes widespread Geant4, ROOT, VMC and others utilities.
  • FairRoot - framework which provides the base classes for IO-management, base classes for event-based simulation and reconstruction.
Experimental data processing
  • Go4 - framework for on-line and off-line processing of experimental data.
  • AccDAQ - library for unpacking and transformation of the raw experimental data in lmd file format produced by Go4 to root format. Output files are applicable for the analysis in the ExpertRoot.

ER extends FairRoot with experiment-specific tasks and adds several features which enables to use it for full live cycle of low-energy physics experiment.
