Scintillation light

Yes…I checked the stepping action, there is the “c”

but for other run, I read alll the current runs and the log ends with the root file closing!

Yest it is the crossing geometry CoupledTransportation

Now I tried to write

	auto proc_man = step->GetTrack()->GetParticleDefinition()->GetProcessManager();
						G4String proc_name = step->GetPreStepPoint()->GetProcessDefinedStep()->GetProcessName();
					//	 G4cout << "Process " << proc_name <<  G4endl;
    					G4int n_scint = 0;
						 if(proc_name == "Scintillation"){
						 	G4Scintillation* scint = new G4Scintillation("Scintillation");
						 	n_scint    = scint->GetNumPhotons();
					       	analysisManager->FillNtupleDColumn(8,0, n_scint);
					       		analysisManager->AddNtupleRow(8);  	
				            }

out of the “if”… and to save the scintillation photons in a new root ttree…I simulated 3*10^6 electrons, but I don’t get scintillation photons…
I really don’t understand…
