Hi Baptiste,

> Is there any way to limit the number of reflection of a particle?

Yes, you can in your UserSteppingAction. How to count reflections, please see the /extended/wls example WLSSteppingAction.cc (fBounceLimit)

No, not by vanilla Geant4, neither would a real photon. A real photon gets eventually absorbed because no reflective surface is perfect.
