[Gate-users] Simulation using neutrons

Tue Nov 20 10:48:57 CET 2018

Hello Ezzat Elmoujarkach,

could you add some more information about your simulation,
i.e. which version of GATE you are using and maybe also the m.mac-files
concerning the physics. This could be useful to  help you in this matter.

Kind regards,

Uwe Pietrzyk

I noticed that the neutrons interact with the world material (air or vacuum) producing electrons and gamma. However, as soon as they touch any object (water phantom, a sheet or anything in the simulation) the neutron deposit all it's energy in the first layer of the object and no secondary radiations are produced. Is this how the simulation should work? or there is something wrong I need to fix?
