None Boundary process and copies of the mother volume 

Forum: Processes Involving Optical Photons

Hello,

    I'm a beginner of Geant4 and I'm trying to simulate a scintillator.
My detector is constituted by an exagonal tube, each edge is a separate
scintillator. To build it I'm creating a trapezoid, which is my mother
volume, and inside it I place my scintillator (a smaller trapezoid) and
a shit of teflon on the external surface, so that my mother volume is
completely filled. Then I position it at different angles and I get a tube.
The beam axis is the tube axis, and particles are emitted with a given
theta with respect to the beam axis.
I've implemented the scintillation process as described in the manual.
Now I should make completely reflective the surface between the teflon
and thi scintillator. I have chosen the optical surface dielectric_metal
(Is it correct?)
When I place only one copy of my mother volume everything works fine and
my photons are reflected, but when I place more than one copy my photons
are not reflected anymore by the teflon... Where am I wrong? Cannot I
use mother volume copies when I have boundary processes? Is there an
other way to do that?
Thank you very much for your help
Cheers
Paola
