Geant4 Python Application

⚠️ This project is currently in a very early stage of development ⚠️

The goal of this project is to provide an accessible pythonic interface to do radiation transport simulations with Geant4.

The goal is not to provide a full python interface to Geant4, but rather to provide a high-level interface to a generic Geant4 application which is highly configurable.

If you are looking for a full set of python bindings for Geant4, I recommend looking at geant4_pybind.

• Configurable Geant4 application written in C++
• Python interface to the application via pybind11
• The complete event data is available as an awkward array for further analysis

A lot of work has been done to make the installation as easy as possible. This package is fully pip installable and should work on all major platforms.

The package itself does not contain any Geant4 data files. These files are needed to perform any kind of simulation. They will be downloaded to a temporary directory automatically during simulation startup.

pip install -i https://test.pypi.org/simple/ geant4-python-application==0.0.2.dev1

from geant4_python_application import Application, basic_gdml

# The data files will be downloaded to a temporary directory the first time this is called
app = Application()

app.setup_manager(n_threads=4)
app.setup_physics()
app.setup_detector(gdml=basic_gdml)
app.setup_action()

app.initialize()

events = app.run(n_events=100)

print(events)
