Re: FLUKA: Max. number of USRBIN binnings
The easiest way is to use USRBIN to score track-length of neutrons in a
regular mesh. Then use the extra weighting option EXTRAWEI with a COMSCW
routine to
select the exact range of energies you want or to multiply by a reaction
cross-section so that you can score the resulting density of interactions
directly. Remember track-length normalized to volume is fluence!
