None secondary neutron generation from proton beam

  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");
 G4VPrimitiveScorer* primitive;
  //primitive = new G4PSTrackLength("TrackLength");
  primitive = new G4PSSphereSurfaceCurrent(psName="Current", fCurrent_In);
  //primitive = new G4PSPassageCellCurrent(psName="Current", fCurrent_In);
  primitive ->SetFilter(neutronFilter);


I am getting some score but with RMS value almost 10 times higher than mean neutron value. I used "FTFP_BERT" physics. Here I am attaching my, and (Note: I have edited example/basic/B4d)

Kindly give me some suggestion in this regards.
