May be it just come from the fact that you don't have any primary carbons to get some secondary neutrons in your detector. As it works with a neutron beam....it seems to me that it's likely something like that.

So I use Filter to select neutron as the following lines: ...... /gate/actor/[Actor Name]/addFilter particleFilter /gate/actor/[Actor Name]/particleFilter/addParticle neutron ...... The result is zero.Nothing. I can't obtain the dose of secondary neutron. But if the source is neutron beam, the dose of neutron beam can be obtained in simulation. Why? What's the [particle name] of neutron in Gate?
