Dear Anton,
thank you very much for your advice, may I ask you also about the output
results of a USRBIN score? We read in fact from the manual: "The results
from USRBIN are normalised per unit volume and per unit primary weight,"
does it mean that for energy deposition in order to get GeV/(cm2 s) out
of GeV/(cm3 primary) one needs to multiply Fluka result by the particle
flux (particle/s) and the length in direction orthogonal to the flux of
the region of interest for the scoring?
Thank you in advance for your explanation,
Best regards,
Beatrice

As a good practice, I would try not to use too many parenthesis (you can equally define the geometry without using any parenthesis at all). Also note that if you have too many bodies in a zone definition this can also slow down the simulation. It is better to have more zones with fewer bodies than to have one zone with many bodies.
