    Dear all,
            I have a compound target by tungsten and gold. It is hitted by a 9 MeV electron beam. I want to get the fluence in the tungsten, the gold and 1 meter away ahead of the target. I use usrtrack to get the energy spectrum of fluence, and use usrbin to get total fluence in the correspond point. In my result. the fluence got by usrtrack in the gold and 1 meter away ahead of the target is zero, but the total fluence got by usrbin is not zero. at the same time, the fluence in the tungsten got by usrtrack and usrbin are consistent. I dont know where the error is. please help me!
            Thanks a lot.
