Geant4 Associates International (G4AI)

Objects

G4AI is a not-for-profit company dedicated to promoting the simulation toolkit, Geant4. The objects for which the Company is established are:

• To promote Geant4 in all application areas.
• To enable its members to work on Geant4 as full collaboration members, contributing to its development and benefiting from access to code repositories, etc.
• To advance knowledge and skill in the use of Geant4.
• To provide support for Geant4 users, particularly in non-academic domains.
• To support its members in these activities.
• To generate income for these activities through services and projects offered by its members and the goodwill of Geant4 users.

Geant4 is an open software toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, medicine and spacecraft design.

The two main reference papers for Geant4 are published in

Nuclear Instruments and Methods in Physics Research A 506 (2003) 250-303, and

IEEE Transactions on Nuclear Science 53 No. 1 (2006) 270-278.

An informal introduction to Geant4 may be found in Geant4 - A Simulation Toolkit, Nuclear Physics News, Volume 17 Issue 2, 20.
