A detailed medical physics application for internal radiation. How to Build and Run an Example
Every example contains a README file. Read it. It explains the specific physics list used, the geometry defined, and what the scoring output represents. If you are trying to "download" an example for a specific paper or thesis, check the History file in the folder to see if the physics models have changed in newer versions of Geant4.
These are full-scale applications often contributed by experimental collaborations. A complex setup for proton and ion therapy. download geant4 examples
Specialized setups for testing physical processes like the photoelectric effect or Compton scattering.
Shows how to output data to ROOT, CSV, or XML formats. It explains the specific physics list used, the
Many users prefer browsing the code on GitHub via the official Geant4 mirror to see recent commits and documentation updates. The Three Tiers of Geant4 Examples
Never work directly inside the Geant4 installation directory. Copy your chosen example (e.g., B1 ) to a personal workspace. A complex setup for proton and ion therapy
What is your (medical, high-energy physics, space)? What OS are you using (Linux, macOS, Windows)? Are you getting a specific error message during the build?
