I have noticed in my scintillator simulations that more energy is being being deposited than was initially put in. This can easily be seen when using the LXe example (from examples/extended/optical/LXe) the results are shown below:
Input: 500 keV gamma Total energy deposition in scintillator : 1056.25 (keV)
Input: 1000 keV gamma Total energy deposition in scintillator : 2115.9 (keV)
I have also seen the same effect in a CsI(Tl) detector I have produced, where FTFP_BERT and opticalPhysics physics lists are used. The results for that simulation are:
Input: 500 keV gamma Total energy deposition in scintillator : 563.93 (keV)
Input: 1 MeV gamma Total energy deposition in scintillator : 1.12826 (MeV)
If I disable the opticalPhysics list in the CsI simulation the correct energy is deposited.
Am I missing something about how the total energy is calculated here? Or how to use physics lists correctly?
Many thanks in advance
