I'm trying to find explosives using a 14MeV neutron generator. The main energies I'll see are 4.43MeV of carbon, 5.11MeV of nitrogen, and 6.13MeV of oxygen. These are all prompt gamma rays that come from reacting with fast neutrons. I've tried shielding with 2cm thick lead to see the peak of...

Thank you for your response. I will try again. I would appreciate it if you could let me know if you get any good results by running the code additionally.

I ran the simulation as you suggested, but I still get the same warning: "Warning. No photon-production MT found in acegam. ZAID = 7014.80c." Also, I couldn't see the 10.8MeV peak for nitrogen... What should I do?

Thank you again for your response. I will make the modifications right away and run the simulation. I hope the results turn out well... I will upload the modified file and the results after running the simulation. 4o

bank is full. bank backup file is being created. nps = 1 warning. no photon-production mt found in acegam. zaid = 94239.80c

Thank you for welcoming me. When I ran the simulation without using a physics model, I got a warning: "no photon-production mt found in acegam. zaid = 7014.80c" Additionally, the peak corresponding to the 10.8 MeV energy from nitrogen did not appear. At this point, I ran the simulation up to NPS...

Nice to meet you

I am a student studying MCNP. I am designing a neutron inspector and planning to simulate it using MCNP. The design I am working on involves using a 14 MeV neutron generator to react neutrons with a target and then measure the gamma rays produced using an NaI detector. The energies I am...

Have a good day.
