I see... I guess it may be helpful to give a few more details on my situation.

I have applied a SplitOrKill biasing operator to the hollow volume (shield) surrounding my detector. The operator is based on the Geant4 example under extended/biasing/GB03, which I have modified so that it is applied to the particles moving radially towards the detector. I use about 16 layers and a split factor of 2. Primary particles are generated through GPS from a sphere around my geometry and follow an arbitrary energy distribution form 0.1 to 400 MeV. I then record into a Ntuple a series of values (such as kinetic energy at the boundary, deposited energy, weight of the particle) for each particle entering the detector (I do not keep track whether it is a primary or not). The values I provided in my previous message come from one of the entries of such Ntuples, with the deposited energy calculated as Edep*Weight.

In attachment, you can find the ROOT-generated histograms of the deposited energy and the particle weight of the Ntuple of one of the 50 runs I have.

I do not know if this gives some useful insights...

Thank you.

Francesco
