For this, I am running two separate simulations. In the 1</span></font><font size="-1" color="black"><sup>st</sup></font><font size="3" color="black"><span style="font-size:12pt">, I save the positron production in a .root file, using the PhaseSpaceActor.
In the 2</span></font><font size="-1" color="black"><sup>nd</sup></font><font size="3" color="black"><span style="font-size:12pt">, I use the PhaseSpace .root file as a source for the PET simulation and save the PET data in a .root file. However, I obtain
the majority of positrons in the phantom contour (is this because the PhaseSpaceActor only stores the particles entering and exiting the volumes?).

I already tried to search in the Gate users archive and did not find anything. </span>
