Geant4

Geant4 turns complex particle physics data into visual understanding. As a sophisticated simulation toolkit, it models how particles like protons, electrons, or ions travel through and interact with various materials. Beyond generating precise numerical results for research and development, its powerful visualization suite is central to its utility. Users can watch simulated events unfold in real-time or replay them, observing particle paths, collisions, and energy deposits within a detailed 3D model of their experimental geometry. This immediate visual feedback is invaluable for designing experiments, validating physics models, debugging simulations, and educating the next generation of scientists by making abstract particle behavior tangible and comprehensible.
