Question more primary particles than I shot 

Keywords: primary particle problem

Dear All,

I have a thin layer of so called 'chamber' which is just a box and its purpose is to report me the information about primary particle. When I count them in this sensitive volume with the following piece of code

 if(aStep->GetTrack()->GetTrackID() == 1 && 
    aStep->GetTrack()->GetParentID() == 0) ++primary;

I'm not getting the number of primaries which I asked. For 100 GeV 1000 mu- particles with this counting I'm getting 1002. Is there any idea why it could be possible?

cheers, Iclal
