Question Secondary gamma slice-energy was abscent in Hadrontherapy

Dear Developers:
I tried to add another small region in Phantom in Hadrontherapy 
example as following,


  PhantomN = new G4Box("PhantomN",phantomNSizeX,phantomNSizeY, phantomNSizeZ);
  PhantomNLog = new G4LogicalVolume(PhantomN,water,"PhantomNLog",0,0,0);


  PhantomNPhys = new G4PVPlacement(0,                        // rotation
				    G4ThreeVector(40.*mm,0,0), // transition   
                                    "PhantomNPhys",            // Name
     				    PhantomNLog,               // Associated logical volume
                                    phantomPhysicalVolume,               // Mother volume
   				    false,0); 

Then I tried to do G4parameterision of this small region. I hooked this
region also in sensitivedetector as 
      PhantomNLog -> SetSensitiveDetector(phantomSD);
But in the .aida analysis fils, I can't see the gamma rays energy 
deposit in "secondary gamma slice-energy" over that region. there is 
a gap always. Can anybody tell me what is the problem?

thank you!  
Gao
