Have you activated the pointwise transport ? Because following the FLUKA manual, we have :

"Recoil protons and protons from N(n,p) reaction are produced and transported explicitly, taking into account the detailed kinematics of elastic scattering, continuous energy loss with energy straggling, delta ray production, multiple and single scattering.

The same applies to light fragments (alpha,3-H) from neutron capture in 6-Li and 10-B, if pointwise transport has been requested by the user. All other charged secondaries, including fission fragments, are not transported but their energy is deposited at the point of interaction (kerma approximation)."

Objet : [fluka-discuss]: Problems about ion transportation in a neutron detector!


Recently, I simulate a GEM type neutron detector which has a converter layer of natB4C(natural B) seen in the following figure, and I want to score the fluence/current of the (B,n) reaction products(αand Li+) to the next Al2O3 layer, unfortunately, I always get a ZERO result(seen in the attachments).The abundance of B-10 in natural B element is about 19.8%, so why I can't obtain a positive current value of αand Li+ after the nuclear reaction? I look forward your help, and any help is appreciated!


Best Regards!
