Question energy spectra too ideal? 

Forum: Physics List
Date: 31 Aug, 2011
From: Athreya Shankar <Athreya Shankar>

Hello,

I'm simulating a CsI(Tl) detector, and I'm interested in protons of 1-100 MeV and electrons of 1-30 MeV.

My detector stops protons of low energy, say, 4 MeV completely. When I run a simulation of 100,000 protons of 4 MeV, I get a sharp spike at 4 MeV. But, in reality, due to the intrinsic detector efficiency, the spectrum should be a Gaussian with a mean energy deposition lower than 4MeV. This would be due to the fluctuations in the number of ionisations per event.

Shouldn't GEANT incorporate this INTRINSIC detector efficiency while carrying out the simulation? Or is there some option by which I can tell GEANT to incorporate this efficiency?

Thanks in advance, Athreya
