Question OPTICAL PROCESESS 

Keywords: Border , Optical, Surface, photon
Forum: Physics List

From: <cpobes@unizar.es>

Hello Geantofilos, I'm quite new to Geant4 simulations although I've some years experience in rare processes (BB and DM). I'm trying to simulate the light propagation in a scintillator+Light_Guide configuration. After defining the geometry, the optical surfaces and adding the physics list (following the Geant4 example 6), I see that the light production works OK, at least qualitatively, but the photons stop at the boundaries. I have tried "logicalbordersurfaces" and "logicalskinsurfaces", but the efect is the same as if I leave undeclared the opticalsurfaces, there are no reflexions and no transmisions.

So my question is: Is there any stupid thing a begginer uses to forget and that can explain this behaviour? Or is it something extrange that nobody have faced before and you would need more information to fix the problem? (By the way, I have one of the latest releases of Geant4)

Thank you very much

Ciao
