Note The latest GEARS require Geant4.11. If you are still using Geant4.10, please download v1.5.1 of GEARS from the Release page.
GEARS is a Geant4 Example Application with Rich features yet Small footprint. The entire C++ coding is minimized down to a single file with about 550 SLOC. This is achieved mainly by utilizing Geant4 plain text geometry description, built-in UI commands (macros), and C++ inheritance. It is ideal for student training and fast implementation of small to medium-sized experiments.
- Single small C++ file, easy to manage, fast to compile (a few second on a regular PC)
- Easy switching between well maintained Geant4 reference physics lists without recompilation
