We introduce a new implementation of the Liège cascade INCL4.2 and of the evaporation/fission code ABLA-V3 in Geant4. INCL treats the cascade of hadron, deuterium, tritium, and helium projectiles of energies up to 3 GeV, while ABLA, based on evaporation and fission, provides a treatment of the excited nucleus produced at the end of the cascade. Details of the implementation of INCL and ABLA in ...

The Geant4 physics lists package encompasses predefined selections of physics processes and models to be used in simulation applications. Limited documentation is available in the literature about Geant4 pre-packaged PhysicsLists and their validation. The reports in the literature mainly concern specific use cases. This paper documents the epistemological grounds for the validation of Geant4 pr...

End users run GEANT4 executable les customized and provided by application programmers. GAG (GEANT4 Adaptive GUI) is a GUI for them to run GEANT4 by using commands and by changing associated parameters. We have two implementations of GAG, that is, Tcl/Tk and Java versions. GAG provides them with a tree (Java) or Pull-down menu (Tcl/Tk) of commands, a widget of parameter inputs of variable forma...

Geant4 [ref G1, ref G2] is a simulation toolkit written in C++ using Object-Oriented principles, and re-engineered from the Fortran-based Geant3. As of Geant 3.21, the Fortran code is officially no longer supported. Geant4 is developed and maintained by a world-wide collaboration including centers at CERN, SLAC, FNAL, KEK and others. The code is available without cost at http://geant4.cern.ch, ...

PURPOSE To test and to develop Geant4 (Geometry And Tracking version 4) Monte Carlo hadronic models with focus on applications in a space radiation environment. MATERIALS AND METHODS The Monte Carlo simulations have been performed using the Geant4 toolkit. Binary (BIC), its extension for incident light ions (BIC-ion) and Bertini (BERT) cascades were used as main Monte Carlo generators. For co...

In this note we present an update of the validation of Geant4 hadronic physics against the ATLAS pixel 2001 test-beam data. Furthermore, we also report the comparison with Fluka simulation, using the same Geant4 geometry, navigation and digitization.

The Geometry modeller is a key component of the Geant4 toolkit [1,2]. It has been designed to exploit at the best the features provided by the Geant4 simulation toolkit, allowing the description of the geometrical structure of complex detectors in a natural way, ranging from a few up to hundreds of thousands volumes of the LHC experiments, as well as human phantoms for medical applications or d...

Stereo mini-jet cells will be indispensable components of a future ee linear collider central tracker such as JLC-CDC. There is, however, no official Geant4 solid available at present to describe such geometrical objects, which had been a major obstacle for us to develop a full Geant4-based simulator with stereo cells built in. We have thus extended Geant4 to include a new solid (TwistedTubs), ...
