[Gate-users] Ge68 source

[Marc Chamberland]

Hi!

You can define a Ge-68 source in Gate by using the "ion source" type. See the documentation here: http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.1:Source#Defining_the_type_of_source


So for Ge-68, you would do it like this:

/gate/source/NAME/gps/particle ion 
/gate/source/NAME/gps/ion 32 68 0 0 
/gate/source/NAME/gps/monoenergy 0. keV 
/gate/source/NAME/setForcedUnstableFlag true 
/gate/source/NAME/setForcedHalfLife 23410080 s


You also need to add the RadioactiveDecay process in your physics list (before initialization):

/gate/physics/addProcess RadioactiveDecay


Note that using an ion source will slow down your simulations.

Cheers!
Marc
