[Gate-users] Y-90 source voxelized

[Didier Benoit]

Hi Juan Camillo,

For the source with an ion you have to set the kinetic energy at 0:
/gate/source/sourceY90/gps/monoenergy 0. keV

Then you have to set the source position at the good position, your line:
/gate/source/sourceY90/setPosition 0.0 0.0 0.0 mm
is surely wrong.
You have an example in the folder:
/gate_v6.1/examples/example_PHANTOM_SOURCE/Voxelized_Phantom_Source
The source position depends on the dimensions of your voxelized phantom

Kind regards,
Didier
