Question Scintillator Photons 

Keywords: scintillators, optical photons

From: Michael Famiano <Michael Famiano>

Hello;
  I'm trying to count the number of optical photons striking a 
photodiode attached to a light guide which is attached to a scintillator.  While the number is proportional to (alpha) particle energy incident on the
scintillator, the deviation is very large (~30%) even when I set the
resolution to 0.  Can anyone help me here, or tell me what might be causing this.  I'm following very closely the advanced example "underground physics."  I've tried many things including changing my cuts, but nothing seems to be changing the apparent low resolution.
Thanks,
mike
