From Sept. 28 to Oct. 2, Fermilab had the rare honor and opportunity to host the 20th Geant4 Collaboration Meeting, which gathers detector simulation experts from all around the world every year at a different location.

Geant4 is a simulation software tool developed by a group of about 100 physicists and computer scientists from all corners of the planet to model the passage of particles through matter and electromagnetic fields. Fermilab's part in the collaboration is seven members strong, contributing to Geant4's software and physics and leading research on the next generation of Geant, to be run on future computing architectures.

The Geant4 community includes not only high-energy physicists but also scientists in the fields of medicine, space exploration and security. Accurate modeling of HEP detectors enables physicists to select optimal designs and improve algorithms for data analysis. Space applications include the evaluation of radiation hazards to astronauts and spacecraft components. In medicine, Geant4 is used to design machines and sources for proton and ion therapy and design treatment plans for individual patients. All in all, Geant4 has improved the quality and quantity of the physics produced in a varied array of scientific programs, as evidenced during the first run of the LHC particle physics experiments.
