Plastic Scintillator for cosmic muon

[hani1026]

Dear all,

I wanted to make a plactic Scintillator for cosmic muons.
This is my detectorconstruction.
There are a plastic scintillator and 8 detection areas.

I just want to know the count of photon that enters the detection areas.

The problem is I don’t know which physics list is good for me…
Next is the process I want.

1. Cosmic muon scatters in plastic scintillator, resulting in photons
2. Photons reflect inside plastic scintillator
3. When the detection area is reached, stop and kill & count

_Geant4 Version:_geant4-v11.1.0
Operating System: Mac ventura m1

This is my current physicslist.cc

 #include "PhysicsList.hh"

MyPhysicsList::MyPhysicsList()
{
  new FTFP_BERT();
  RegisterPhysics(new G4OpticalPhysics());  
  RegisterPhysics (new G4EmStandardPhysics()); 
}

MyPhysicsList::~MyPhysicsList()
{
}

Hello,

welcome to Geant4. As a started with G4OpticalPhysics I would advice you to have a look at the examples distributed inside the Geant4 source code (unless explicitly disabled) in the following location examples/extended/optical.

Cheers,
