[Gate-users] Ion source: empty output

[Marc Chamberland]

Hmm… I don’t have experience with the sinogram output, so I’d try looking at the Root singles output. Is it also empty?

Perhaps also increasing the verbosity might help you diagnose what’s going on. I don’t know which verbosity to increase, though! Perhaps:

/event/verbose 1 (or 2 or 3)

See if this produces any messages that might point you in the right direction.

Thanks Marc,

I add this line to the physics list:
/gate/physics/addProcess RadioactiveDecay

and tried to run: again no errors but an empty .sin file at the end.

Any more suggestions?

Hi Débora,

The first thing I would check is that your physics list has the radioactive decay process enabled.

Marc

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
