<p>Dear Users,</p>
<p><br>
</p>
<p>currently I am facing a lot of problems with the scintillation process. I use Gate9.1, Geant4.10.7 and installed everything with the precompiled Version for the VM. I recompiled Gate with Optical = On and LUT_Davis = On.</p>
<p>When I run my simulation I see in root Optical Data and NumScintillation and I should have produced some Scintillationphotons, but neither do I see them in the Hits file nor during the Simulation.</p>

<p>Thats a part of my Hits ascii file. In the last row is a scintillationprocess, but somehow the particle is an electron(electron = 11, photon = 22). How does that make sense, I have no scintillation photons, only secondary produced photons by compton interactions.
<br>
</p>
<p>I've seen the physicslist "optical" a lot but somehow it does not exist anymore.
<br>
</p>
<p><br>
</p>
<p>I use a block consisting of LYSO and a plastic. I've defined their scintillationyield and so on in the materials.xml. When I run the macro, you can see that those parameters are read-in. But somehow theres no scintillation. And I should note that the Singles
output is allways empty.</p>
<p>Of course every layer is defined as crystalSD. And I use a gamma source. </p>
<p>Solutions I allready tried and checked:</p>
