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

The electron and ion beamline and interation point detectors for the electron-ion collider.

10,000 electrons producing photons in the 6mm collimator in the bubble experiments at Jefferson Lab.


========

### Overview:

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. 

   



### Simulations are application independent

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.
