If you are new to Geant4, we recommend that you read this document first. The first part of the document provides a step-by-step tutorial in the use of Geant4; this is for a novice user. The second part describes the usage of the toolkit for practical applications, with a lot of example codes. After reading this part, you will be able to start to write a detector simulation program for most applications/experiments. The third part is for those who want to make more advanced use of the toolkit.

Geant4 provides a series of basic, extended, and advanced examples that demonstrate the use of the toolkit’s capabilities across a range of domains. The Examples Documentation should be consulted for details of these together with the Application Developer Guide above.

For Toolkit DevelopersPermalink

This document is for those who want to contribute to the extension of the functionality to the Geant4 toolkit - for example, to add a new physics process, to add a new particle, etc. It starts with the explanation of the object-oriented analysis and design performed by the original toolkit developers. Understanding this design is mandatory for a new toolkit developer. Then guidance on how to extend the functionality of each class category is given.

Physics Reference ManualPermalink

This is a detailed description of the physics interactions provided in the Geant4 toolkit. The theory, model or parameterization of each interaction is discussed.

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. Improvements in these sections are expected by the next release.
