Due to the complex geometries and physical processes of particles travelling through matter, scientists created a general simulation toolkit called Geant4. This project aims to show three basic Geant4 examples. A simple simulation of a Passivated Implanted Planar Silicon detector was created, like it is used as a diagnostics tool for the FRS-IC. A beginner-friendly guide was also written and is provided on the project website. The second experiment shows how Geant4 can combine nuclear reaction cross-sections and interaction kinematics to calculate neutron induced reaction rates and escape probabilities from a thin foil at the SARONA instrument in SARAF [1]. The last example shows how to read complex tabulated data into Geant4 from other simulation programs. This poster will provide beginners a starting point in the program through the three example projects.
