Particle Physics
Simulation programs play a fundamental role in optimizing the design
of particle physics experiments. For the development of reconstruction
programs they provide the necessary input in the form of simulated raw
data. In the analysis process they are required to understand
systematic effects from detector resolution and acceptance as well as
the influence of background processes.
Geant4
pages
Geant4 is developed and maintained by an international collaboration of physicists and computer scientists. The open and collaborative relationship between the development team and its user communities has led to a two-way transfer of technology, since users in fields other than particle physics actively contribute.
Geant4 Organization
Simulation is equally important in space-based astroparticle physics. Most space probes have to operate for many years without the possibility of physical repair after launch. It is therefore essential to understand the behaviour of all components in the space environment and in particular the effect of radiation on on-board electronics and detectors.

Geant4’s extended set of physics models, handling both electromagnetic and hadronic interactions can be used to address a wide variety of medical applications from conventional photon-beam radiotherapy to brachytherapy (using radioactive sources), and from hadron therapy to boron neutron capture therapy.
