GEant4 Monte-Carlo

gemc is an application based on Geant4 to simulate the passage of particles through matter.

It provides:

• application independent geometry description
• easy interface to build / run experiments
• cad/gdml imports

========

gemc makes easy things trivial and hard things possible.

Users can build and run complex setups with minimal programming knowledge. See for example how to build a TOF with few lines of code.

Experiments can be loaded using a combination of several available factories:

• MYSQL
• TEXT
• GDML
• CAD (STL, PLY, OBJ formats)
• C++ Plugin

gemc can import models from CAD and GDML. Left: the upper gastrointestinal system is modeled in CAD. It can be imported in GEMC and made it sensitive so that radiation doses can be measured. Right: the mighty USS Enterprise NCC 1701-A can be used to shoot protons torpedos.

Once the user defined setup is loaded, it is translated in geant4. This includes:

• geometry
• materials
• mirrors
• physics list
• digitization
• electromagnetic fields

All particles are transported through matters and produce radiation, hits, secondaries. The geant4 results are then collected and organized according to user preferences.
