Advanced examples are Users’ applications that simulate a specific
experimental setup
Investigate, evaluate and demonstrate Geant4 capabilities in
various experimental environments
Provide guidance to Geant4 users in realistic experimental
applications
Provide connection between developers and users of GEANT4

General maintenance and cleaning of obsolete methods Migration to
g4tools and MT Bug fixes on:
• ChargeExchangeMC • Microelectronics • hadronterapy • Microbeam •
radioprotection
Recent new developments: • Hadrontherapy • Human_phantom

• Simulation of the whole ELIMED (ELI-beamlines MEDical
applications) beamline completed • Simulations of the beam
transport systems carried out (quadrupoles and energy
selector):
-Magnetic elements simulated and tested (geometry and field for
tracking) -Grid map for magnetic fields implementation (benchmark
with reference analytical
transport codes) -Simulation outputs compared with experimental
data
• Simulation of the dosimetric system prototypes carried out
-Faraday cup fully simulated (electric field implemented and
tested)
