[Gate-users] Defining a source to analytical phantom

[Emilie Gaudin]

Hi,

You can define a multiple source the same way you define a single source.
Since you don't seem to know how to define a (hot and/or cold) source you can read this part of the documentation :
https://opengate.readthedocs.io/en/latest/source_and_particle_management.html

For example,

# SOURCE 1
/gate/source/addSource source1
/gate/source/source1/setActivity 10 kBq
/gate/source/source1/gps/particle e+
/gate/source/source1/gps/energytype Fluor18
/gate/source/source1/setForcedUnstableFlag true
/gate/source/source1/setForcedHalfLife 6586.0 s
/gate/source/source1/gps/type Volume
/gate/source/source1/gps/shape Cylinder
/gate/source/source1/gps/radius 0.5 mm
/gate/source/source1/gps/halfz 10 mm
/gate/source/source1/gps/angtype iso
/gate/source/source1/gps/centre 0.0 0.0 0.0 mm
/gate/source/source1/attachTo volume1
/gate/source/source1/visualize 10 green 1

# SOURCE 2
/gate/source/addSource source2
/gate/source/source2/setActivity 10 kBq
/gate/source/source2/gps/particle e+
/gate/source/source2/gps/energytype Fluor18
/gate/source/source2/setForcedUnstableFlag true
/gate/source/source2/setForcedHalfLife 6586.0 s
/gate/source/source2/gps/type Volume
/gate/source/source2/gps/shape Cylinder
/gate/source/source2/gps/radius 1.0 mm
/gate/source/source2/gps/halfz 10 mm
/gate/source/source2/gps/angtype iso
/gate/source/source2/gps/centre 0.0 0.0 0.0 mm
/gate/source/source2/attachTo volume2
/gate/source/source2/visualize 40 green 1

# SOURCE N
