Dear FLUKA experts,
I am trying to evaluate radiation damage by low energy heavy ions in a
carbon thin target. I am using 4 MeV (total energy) Carbon primaries that
hit a small volume target 500 nm thick 20x20 um2. I attach my input files. I
have set PRECISIO as default and also a MULSOPT card, but I have noticed
that the results, and error in scored quantities too, are the same both with
MULSOPT card enabled and with this card disabled. Moreover, if MULSOPT is
enabled simulation time is about 25 ms/primary, whereas if disabled it is
0.05 ms/primary, but there is no difference in results. Is there something
wrong in my simulation parameters? Many thanks.
MULS. ENABLED MULS. disabled
