[Gate-users] RE: energytype source

[Marcin Balcerzyk]

Dear Anayisse.

You have the typical ones listed in section 7.2.2 of users guide. Besides
the ones you mentioned there are FastI124 and Backtoback. Otherwise you have
to use isotopes/ions:

/gate/source/NAME/gps/particle ion
/gate/source/NAME/gps/ion 8 15 1 2

Which is oxygen 15, of charge +1 and energy 2 MeV. You need a module
G4EMLOW3.0 for Gate 3.0.0 and Geant4, ver 8... which is normally not needed
by Gate (I think) for Fluor18 source. Look at Geant web pages where to
install it. I have it at /geant48/data folder as a subfolder. Contrary to
Fluor18 source, you have decay times listed in definition of ion source.

Users guide warns that the simulation is slower with the general ion source,
but I used one with pretty complicated decay and it worked fine. In case of
ion sources with many branches specify well the /gate/physics part - look at
benchmarkPET, at macro physics.mac.

Hi Gate Users,

I need your help please

I would like to know if GATE offers keywords to simulate other positron
sources ? or it is limited to Fluor18, Oxygen15 and Carbon11  ? 


Thank you

Anayisse
