<div dir="ltr">Hello Gate users,<div><br></div><div>I am using GATE to model pieces of scintillating material and a PMT. Recently I have been comparing some simulations to my data, and am trying to figure out where certain discrepancies come from.</div>
<div><br></div><div>To analyze data from my simulations, I use a program I have written to parse the Hits.dat file such that the number of photons detected per parent particle is stored into a histogram - analogous to a spectrum. However, comparing this to my experimental spectra, the simulations seem to have many more low energy (low # of photons detected) counts than my experimental data. Are there any possible reasons for this? Is there a threshold (either for scintillation or detection) that I should take into account? </div>
<div><br></div><div>Also I have read a little bit about the digitizer and 'opticaladder,' but I cannot find a concise description of what it does, and what the Singles.dat file means. What makes a 'single'? Is this something I should consider using for my analyses?</div>
<div><br></div><div>Please help, and thank you,</div><div><br></div><div>-Amy</div></div>
