Geant4: Simulation of Particle Interactions with Matter


Geant4 is a software toolkit for the simulation of the interaction of particles with matter, developed and maintained by a world-wide collaboration of physicists and computer scientists. Its application areas include high energy physics experiments, astrophysics and astroparticle physics, space science, medical physics and medical imaging, nuclear physics, radioprotection and radiation background studies. It exploits advanced software engineering techniques and Object Oriented technology to achieve transparency of the physics implementation, as well as openness to extension and evolution.

Geant4 provides a wide set of tools for all the domains of detector simulation, such as Geometry modeling, Detector Response, Run and Event management, Tracking, Visualisation and User Interface. An abundant set of Physics Processes handle the diverse interactions of particles with matter across a wide energy range, as required by Geant4 multi-disciplinary nature; for many physics processes a choice of different models is available. 

The Geant4 source code and libraries are freely available, accompanied by an extensive set of user documentation. 

The course provides an overview of Geant4 capabilities, and illustrates in detail the major features available in the toolkit to simulate an experimental set-up. Specific lectures are devoted to Geant4 capabilities for medical applications. Finally, the students are guided through a real-life simulation example, offering a practical implementation of the basic concepts of a user application. As a result of the course the students would learn how to develop simulation applications based on the Geant4 Toolkit. 

To best profit of the course, some basic knowledge of the C++ computing language  is recommended.
