Geant4 ( eng. GEometry ANd Tracking - geometry and tracking) [2] [3] [4] - a toolkit for modeling the passage of elementary particles through matter using Monte Carlo methods . Developed at CERN in an object-oriented C ++ programming language . The first releases were released in 1998.

It is a further development of previous versions of GEANT , substantially revised and supplemented. Versions 1, 2, and 3 were written in Fortran .
As stated on the project’s official website, “applications include high-energy physics and nuclear reaction research, medicine , particle accelerators , and space physics research.” The software is used in many research projects around the world, including in Russia . The base environment for launching Geant4 is Scientific Linux , but there is compatibility with other systems based on both Linux and Microsoft Windows .
The source code for Geant4 was initially publicly available. A special license confirming the openness of the software appeared only in version 8.1 dated June 30, 2006 (Geant4 Software License).
Libraries for Geant4
In total, about a dozen class libraries and nuclear reaction cross section libraries are used for Geant4. Below are some of them:
- CLHEP (from the English A Class Library for High Energy Physics - a library of classes for high energy physics) is a library written in C ++ and provides utility classes for general work with numbers, vector algebra, geometry, pseudorandom number generators in an application to high physics energies.
- FreeHEP is a library written primarily in Java, similar to CLHEP.
