Geant4 simulation of an alpha particle inside an aluminum box (which is actually the world)
To compile,
cmake -B build -S .
cmake --build build
To run,
./build/main
A file called output.txt will be generated. It contains energy deposition dE at every step and the sum of the dE at the end. For 1 MeV alpha, there is 1 step. For 10 MeV, 1800 steps, for 1 GeV 170k steps.
Tracks of alpha are very small, so zoom is needed in order to visualize them.
