This example shows the dose distribution in water along the incident proton beam. This example is very similar to the monoenergetic proton pencil beam example. The difference is that the beam is defined with realistic geometry. For the generation of the proton beam, instead of particle gun, we use general particle source. For more details about '''G4GeneralParticleSource''' class look [https://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/ch02s07.html here].

The volume of the water cube is divided into slices perpendicular to the incident beam. The slices are created using class '''G4PVReplica'''. The energy and dose are scored using classes '''G4UserSteppingAction''' and '''G4UserRunAction'''. Alternatively, the energy and dose are scored using class '''G4ScoringManager''' by defining scoring mesh. There is an option to chose among several EM and the '''QGSP_BIC_EMY''' physics lists.
