[Gate-users] Ion source - timestamp problem GATE 6.1

[STRYDHORST Jared]

What version of GATE and Geant4 are you using and what ion?
GATE schedules the decay of ions itself according to the activity set by the user. To do so, it calls a function that sets the lifetime of the ion in Geant4 to zero so it decays immediately when it's created. However, in version 10 (.1?, .2? I don't know exactly when the change was made.) of Geant4, the function (SetPDGLifeTime()) now ignores any attempts to modify the lifetime of an ion. So the ion is created by GATE, but then Geant4 calculates the decay time according to the real half-life of the ion.

Objet : [Gate-users] Ion source - timestamp problem GATE 6.1

Dear all,

I am trying to use an ion source for a PETscanner.
The simulation provides strange values for the time stamp of the singles.
The parameter  "setTimeStop"  was set to 50s, but the timestamp of the first detected single was 3.4x10^17 s.
I would like to know if there is any solution to this problem.
Best regards,

Enrique
