<p class="MsoNormal">Hello David,<o:p></o:p></p>
<p class="MsoNormal">Thank you for your reply. I have done a bit more testing and am no closer to understanding what’s going on!
<o:p></o:p></p>
<p class="MsoNormal">I am getting very different results between defining geometry as Boxes vs STL meshes.<o:p></o:p></p>
<p class="MsoNormal">And I constantly get the following warning when Fluence Actor is enabled, even if there is only one sensitive detector.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="margin-left:.5in">*** G4Exception : DET1010 issued by : G4SDStructure::AddNewDetector()<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">crystal had already been stored in /gate/. Object pointer is overwritten.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">It's users' responsibility to delete the old sensitive detector object.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">*** This is just a warning message. ***<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What I’m trying to do is evaluate detector sensitivity by comparing the number of primary emissions entering a crystal to the number of singles I record. I think I may be able to get the info I need from the Phase Space Actor, so I’ll try
that.<o:p></o:p></p>
