The Geant4 is a robust and widely-used computational framework for particle physics, nuclear physics, and other domains. Developed by an international collaboration of scientists and engineers, G4 delivers a adaptable and modular framework for recreating the interplay of particles with matter. In this handbook, we will provide an in-depth overview to using G4, covering its installation, configuration, and application.

Define the G4INSTALL system parameter to the directory where Geant4 is located. Assign the G4LIB environment value to the directory where the Geant4 libraries are found.

Root: Geant4 can write output in the Root format, which can be analyzed using the Root analysis framework. CSV: Geant4 can write output in the CSV format, which can be simply imported into most spreadsheet programs.

Introduction with the Toolkit

Bodies: Geant4 replicates the engagement of bodies with material. Elements can be both main (generated by the user) or secondary (generated by reactions). Elements: Geant4 supplies a database of elements with their corresponding characteristics, including as mass and composition. Regions: Geant4 utilizes a layered system to outline the layout of the model. Volumes can be both dense or void.
