Dear FLUKA experts
I’m simulating the recoil-protons produced by cosmic rays entering the outermost atmosphere, in two cases, the global atmosphere and the atmosphere in a particular latitude. Meanwhile, I’ve removed the geomagnetic cutoff in both cases.
I don’t know why the average recoil proton energy of the two scenarios is always different when the magnetic field is taken into account or when the magnetic field is not taken into account.
5-test-1_PROTON_QUANQIU in the additional file considers the global atmosphere, while 5-test-1_PROTON_DONGGUAN considers the atmosphere at a specific latitude.
Hope you can help me.
Thank you,
Yongce

Dear @chenjianqi ,
I am not sure I get your question, but from the files you have provided I can see that you are using the same *.sur file for both the local/global Earth model.
Please note that when creating a local geometry, an atmloc.sur file is created containing data used by FLUKA runtime, and normalization areas. Therefore, you should make sure to use the proper *.sur file for each model, otherwise the results might not be comparable.
Regards,
Angelo
