[Gate-users] How to repeat a source without a phantom (Edit question)

Hi Suhwan Kim,

I know your subject line states "without a phantom", but here's an alternate approach that might work for you without a voxelized structure. Define a parent volume that contains your repeating structure, define your source with the same geometry as your parent volume and attach it to the parent volume, then forbid<https://opengate.readthedocs.io/en/latest/source_and_particle_management.html?highlight=forbid#defining-a-cold-source> the source from emitting activity in the parent volume. This should distribute your activity across the repeating daughter structures.

Hope this helps,

Hi Shwan,

Your question is interesting, but as per my knowledge Gate doesn't have repeating structures for sources.

I think you can achieve the multiple source objectives by using voxelized structure<https://opengate.readthedocs.io/en/latest/voxelized_source_and_phantom.html#voxelized-sources>.

Dear gate user

I'll edit the question a bit.

I don't mind using Phantom to make multiple sources.

I need 100 sources each horizontally and vertically. (10000 Sources)

And 10000 sourceIDs should be output.

help me please.

Hello GATE users.

I am suhwan kim

How do I repeat a point source without a phantom?

I am trying to create a source with 100 rows and 100 columns.

The spacing between sources is constant.
