Dear FLUKA experts and users,
I have run simulations to obtain the neutron fluence spectrum (please, see
the attached files) of a simplified target for the production of 18F. As I
saw previous threads on similar topics the advise is to use isolethargic
neutron spectrum for presenting such results. My question is about the
normalization of the obtained results. I guess I should use some
coefficient on the y-scale? Since, at first glance, the peak of the
spectrum is at the expected energy (about 3.2 MeV) and the obtained result
for the number of neutrons generated per primary proton is also reasonable
((Part/pr) 1.1626173E-02 +/- 2.1345012E-02 %) but the values on the
y-scale are a lot lower than I expected, about two orders of magnitude. Do
I have an error in the input file itself or I just need to normalize the
results?
Best regards,
Angel
