I have a plastic scintillator 'A', and one 1 MeV proton is incident on it. the scintillator is surrounded by reflectors on all sides, except one side, through which it is required that the photons pass out of the scintillator. I have created a dummy detector(vacuum) DummyDet at this opening, and I have used the following logic to count the photons passing out:
if(partEnergy>0 && particle==G4OpticalPhoton::OpticalPhotonDefinition())
G4cout<<"these are the photons entering the first dummy detector:"<<partEnergy/eV<<G4endl;
But using this logic, the photons counted is much above (around 20000) what is being generated (around 13500). What is the mistake here?
if I use another logic, which is to have an absorber very close to the opening(not touching the plastic scintillator), then the number of photons counted is reasonable(around 7500).
Kindly clear this doubt.
Thanks in advance
