Dear Fluka experts,
I simulated a beam of protons hitting on the Pb target, and I wanted to collect all the neutrons information(mainly position and direction), so I use the usrdump by writing a MGDRAW.F.
At the moment, I want to get all the neutrons produced, but I don’t want to collect them twice, so I use LLOUSE:
However, the results were wrong, because when I set the energy of protons to 500MeV, I only got about 6.3 neutrons/primary.
I don’t know the reason and how to revise. Can someone help me analyze it or indicate which module I need to study？
Any advice, Thanks~ !
