[Gate-users] Ion source: empty output

[Débora Salvado]

Dear Gate users,

I have my main .mac file parameterized for different sources.

It works for the following definition of source:

/gate/source/addSource source1
/gate/source/source1/gps/type Point
/gate/source/source1/gps/centre 0. 0. 0. mm
/gate/source/source1/gps/particle gamma
/gate/source/source1/gps/energy 159. keV
/gate/source/source1/setActivity 3000000. Bq
/gate/source/source1/gps/angtype iso

However, when I try to run it for an ion source, with this definition:

/gate/source/addSource source1
/gate/source/source1/setActivity 3000000. Bq
/gate/source/source1/gps/type Point
/gate/source/source1/gps/centre 0. 0. 0. mm
/gate/source/source1/gps/particle ion
/gate/source/source1/gps/ion 53 123 0 0
/gate/source/source1/setForcedUnstableFlag true
/gate/source/source1/setForcedHalfLife 47520. s
/gate/source/source1/gps/energytype Mono
/gate/source/source1/gps/monoenergy 0. keV
/gate/source/source1/gps/number 1
/gate/source/source1/gps/angtype iso
/gate/source/source1/gps/mintheta 0. deg
/gate/source/source1/gps/maxtheta 180. deg
/gate/source/source1/gps/minphi 0. deg
/gate/source/source1/gps/maxphi 360. deg

It runs but the output projection file .sin is empty...
When I run with the first source instead, I get a .sin file with some data.
I don't really have an error, it's just that my simulation doesn't generate
anything. Can someone help me figure out what's happening?

Regards,
Débora Salvado
