so I have a scintillator bar with specified dimensions 5x10x75 cm(75 cm long). I am shooting muon beam right ( 1 GeV Kinetic energy) at the center of the scintillator bar cross-section (5x10). I have also placed a sensitive detector at the end of one of the scintillator bar with specified properties which I adapted from OpticalNovic examples. The scintillator bar is NOT currently wrapped.
I believe I have correctly implemented optical properties.
And my sensitive volume is placed right after the scintillator bar and I Believe I implemented the sensitive detector correctly, however I noticed that most of optical photons escaped at the front edges of bar. Is this intended effect ?
In the image below I have placed a separate sensitive detector away from bar slightly for visual imaging.
For instance, the number of scintillation photons produced by bar is roughly 600,000 while I get number of optical photons exiting the scintillator bar into sensitive detector to be more or less around 70,000. Is this number reasonable or too small (a reference would also help) ?
