1. Geant4 Working Groups & Coordinators

Following principles of object oriented analysis and design, the software of the Geant4 toolkit is decomposed into categories. Usually several categories are grouped together to form a working group. These working groups a responsible for the development, support and documentation of their categories. In addition there are working groups for documentation, testing and software management. Each member of the collaboration is working for one or several working groups.


Geant4 is a toolkit for the simulation of the passage of particles through matter. Its areas of application include high energy, nuclear and accelerator physics, as well as studies in medical and space science. The three main reference papers for Geant4 are published in Nuclear Instruments and Methods in Physics Research A 506 (2003) 250-303,  IEEE Transactions on Nuclear Science 53 No.
