  1. User Documents and Examples II KOI, Tatsumi Geant4 Tutorial at ORNL 10-March-2011

  2. User Documents • http://geant4.web.cern.ch/geant4/support/userdocuments.shtml • Application developers manual • Toolkit Developers' Guide • For those who want to contribute to the extension of the functionality to the Geant4 toolkit • Physics Reference Manual • A detailed description of the physics interactions provided in the Geant4 toolkit. Geant4 Tutorial at ORNL 10-March-2011

  3. Toolkit Developers' Guide • URL • http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForToolkitDeveloper/html/index.html • For developers and experienced users of Geant4. • Already familiar with functionality of the Geant4 toolkit as explained in the ``User's Guide For Application Developers“. • A working knowledge of programming using C++ is assumed • Describing • A description of the object-oriented design of the Geant4 toolkit • philosophy behind design choices •  A guide for users who want to extend the functionality of Geant4; adding new solids, modifying the navigator, creating new fields, etc. Geant4 Tutorial at ORNL 10-March-2011

  4. Physics Reference Manual • URL • http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/PhysicsReferenceManual/fo/PhysicsReferenceManual.pdf • No more html version, only pdf version is available. • The purpose of this manual • to present the theoretical formulation, model, or parameterization of the physics interactions included in Geant4 • to describe the probability of the occurrence of an interaction and the sampling mechanisms required to simulate it, and • to serve as a reference for toolkit users and developers who wish to consult the underlying physics of an interaction. • The Physics Reference Manual contains gaps in documentation which correspond to un-implemented interactions. There are also a few sections in which documentation is slight. Geant4 Tutorial at ORNL 10-March-2011

  5. Examples • Novice Examples • Extended Examples • Testing and validation of processes and tracking • Demonstration of Geant4 tools • Extending the functionality of Geant4. • Advanced Examples • Geant4 advanced examples illustrate realistic applications of Geant4 in typical experimental environments Geant4 Tutorial at ORNL 10-March-2011

  6. Extended Examples http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/ch09s02.html • Geant4 extended examples serve three purposes: • testing and validation of processes and tracking • Electromagnetic (TestEm0 – TestEm18) , Hadronic • Radioactivedecay, Polarisation • Field (field01 – field04) • Geometry (olap) • demonstration of Geant4 tools, • Analysis, event generator, g3tog4, persistency • Biasing (B01-B02), optical, run and event • Parameterisations (GFLASH • extending the functionality of Geant4. • Paralle computing (ExDINE, MPI and TopC) Geant4 Tutorial at ORNL 10-March-2011
