Hi, I am beginner in Geant4. I want to get number of secondary neutron due to incident proton beam (250 MeV pencil beam) on a cylindrical target. I used Multifunctional detector and neutron filter like below auto Detector10 = new G4MultiFunctionalDetector("dect_10"); G4SDManager::GetSDMpointer()->AddNewDetector(Detector10); G4VPrimitiveScorer* primitive; //primitive = new G4PSTrackLength("TrackLength"); primitive = new G4PSSphereSurfaceCurrent(psName="Current", fCurrent_In); //primitive = new G4PSPassageCellCurrent(psName="Current", fCurrent_In); primitive ->SetFilter(neutronFilter); Detector10->RegisterPrimitive(primitive); SetSensitiveDetector("detc10LV",Detector10); I am getting some score but with RMS value almost 10 times higher than mean value of neutron . I used "FTFP_BERT" physics. Here I am attaching my Detectorconstuction.cc, eventaction.cc and runaction.cc
(Note: I have edited example/basic/B4d according to my requirement.)
Kindly give me some suggestion in this regards that where is the problem ? Need your expert opinion on this please.
