Re: FLUKA: Problem

 Dear Yann
the USRBIN results are in  particles/ cm^2
To get the integrated fluence you have to multiply by the surface. This
corresponds to the particle number ONLY IF particles are travlling
perpendicularly to the surface you are considering. Maybe it would be
better to use the USRBDX card to score the particle current.
