[Gate-users] optical-photon-simulation-result-interpretation

[Debendranath Sahoo]

June 22

Dear Gate-users,

I am simulating optical photons in a 5cmX5cm LaBr(Ce) crystal in GATE 7.0.
I have chosen a Beam type gps source of gamma ray (140 keV) 1 Bq for 1 sec
which means *only one* incident gamma photon on the crystal. The 64X64
anodes on the PSPMT detect the scintillation photons generated. However, I
also get a lot of trajectories passing through the system. What do these
trajectories correspond to? Are these gamma rays from Compton events? But I
started with just one gamma photon incident on the crystal! What does one
make out of this? I am enclosing the macro files along with a jpg file
showing the view I get in display. My main file to run is named
"newcam.mac".

Any interpretation will be appreciated.
