Dear Fluka experts,
I am analyzing the efficiency of a liquid scintillator and I
can not understand why at varying the energy of the incident neutron
beam, I do not obtain the same neutron fluence at the region of the
scinitillator.
By integration of the neutron spectrum there (from a USRTRACK score)
I obtain in fact a varying neutron fluence, though not expected:
from 5.9*10^-3 at 4MeV to 7.37*10^-3 at 20 MeV of neutron energy.
Can you tell me what is wrong with the analysis (in attachment)? I
would like to score efficiency as: integrated proton
fluence/integrated neutron fluence (at varying neutron energies) but
I do not obtain realistic results, probably due to this mismatch.
Thanks in advance,
Sincerely
Beatrice
