[Gate-users] Optical Photons not traversing materials

[Robert Wilson]

I'm trying to simulate a series of scintillation events within a crystal by
starting an isotropically random beam of optical photons from within the
crystal. The problem I'm having is that none of the photons are escaping
the crystal once I add the Optical Boundary process. Because of this I am
unable to know which photons would actually make it to the surface of the
PM in the event of scintillation. If anyone knows of this problem or knows
how to fix it, please let me know. I feel like I have exhausted the
material in the user guide... unless I'm just failing to look in the right
place. Help please.

Sincerely,
*R. Kevin Wilson*
