<p class="MsoNormal"><span style="font-size:12.0pt;mso-fareast-language:EN-US">I have no idea about the optical properties of your scintillator (BCF12) neither I’ve used GATE v9 for optical transport. However, what I could see in your Materials.xlm file is
that there’s no information about the emission spectrum of the BCF12 (i.e. fast component and/or slow component). Once you include it, you should be able to produce the optical photons and visualise them using the Qt.

<p class="MsoNormal"><span style="font-size:12.0pt;mso-fareast-language:EN-US">About tracking your optical photons within the fibre, you’ll need to define it as a GATE sensitive detector and attach a detector surface to your SiPM volume (so you can actually
detect them). <o:p></o:p></span></p>

</div>
<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black">my fiber is a multi-clad (two cladd), both cladding is composed of PMMA, the core is composed of (99%) polystyrène and (1%) paraterphenyl (the core material is named in the macro BCF12). The core
is scintillating.<o:p></o:p></span></p>
</div>
<div>
<p class="MsoNormal"><span style="font-size:12.0pt;color:black">after installing 9<sup>th</sup> version of Gate, i wrote my macro which is attached, and i add optical properties of BCF12 to materials.xml, i activate scintllation process in physics, after verify
geometry, i want to verify the scintillation process, so in the visualization i can't see the scintilating photons, can you please help me, i don't know if i make some error, my visualization is in Qt mode.<o:p></o:p></span></p>
