Geant4 Extended Examples

The set of "extended" examples is covering various use-cases and may require some additional libraries besides of Geant4.

Extended level examples:

• analysis
  • Histogramming through the AIDA interface
• biasing
  • Examples of event biasing, scoring and reverse-MC-
• common
  • A set of common classes which can be reused in other examples demonstrating just a particular feature
• electromagnetic
  • Specific EM physics simulation with histogramming
• errorpropagation
  • Use of the error propagation utility (Geant4e)
• eventgenerator
  • Applications using interface to HepMC
• exoticphysics
  • Exotic simulation applications (classical magnetic monopole, etc...)
• field
  • Specific simulation setups in magnetic field
• g3tog3
  • Examples of usage of the g3tog4 converter tool
• geometry
  • Specific geometry examples and tools: OLAP tool for detection of overlapping geometries
• hadronic
  • Specific hadronic physics simulation with histogramming
• medical
  • Specific examples for medical physics applications
• optical
  • Examples of generic optical processes simulation setups
• parallel
  • Examples of event-level parallelism in Geant4 using the TOP-C distribution, and MPI technique
• parameterisations
  • Examples for fast shower parameterisations according to specific models
• persistency
  • Persistency of geometry (GDML or ASCII) and simulation output
• radioactivedecay
  • Examples to simulate the decays of radioactive isotopes and induced radioactivity resulted from nuclear interactions
• runAndEvent
  • Examples to demonstrate how to connect the information between primary particles and hits and utilize user-information classes
• visualization
  • Specific visualization features and graphical customisations

Common classes for extended examples:

In order to reduce code duplication and to reduce the number of variants of the code of same kind, we define a set of common classes which can be reused in "feature" examples demonstrating just a particular feature. This module is going to be enhanced in future. Currently it provides the following sets of classes:

• analysis : ExG4HbookAnalysisManager - the analysis manager class for HBOOK

• detectorConstruction : two simple detector construction classes with a messenger

• physicsList : ExG4PhysicsList00 - physics list with geantino and chargedgeantino only

• primaryGenerator : two simple primary generator classes (with G4ParticleGun and G4ParticleGeneralSource)

• userActions : event action and run action classes with messengers
