<div dir="ltr">I am using an optical point source, the source is below a glass cylinder and I have defined a dielectric_metal boundary between mother volume of the glass cylinder and the glass cylinder, so that optical photons are detected. But the ascii optical adder file and ascii hit files are empty indicating that no photons are detected. <br>
<br>(Is there any condition that only optical photons generated from a scintillation process only will be detected ? because when I define a scintillating crystal between the source and glass cylinder optical photons are detected)<br>
<br> What should I do inorder to detect these photons ? I am using Gate v-6.1<br>
