Hi All,

I found the mistake I made. It is the SetBirksConstant(0.126*mm/MeV) function in DetectorConstruction that attenuated the photon yield. This function cause a non linearity between photon number and deposited energy. And the 0.126*mm/MeV value is for organic scintllator, not for the ZnS I used.

Thank you so much!
