Hi Hantao,
sure that FLUKA can do this.
If you want to study the problem, I think you have to follow two steps:
- build your proton source through the user routine source.f, which you
call via the SOURCE card. In the include file (FLKSTK) you find
the stack of the primaries: the Agestk variable is the age of the
particle, in seconds. You can add the spread due to your proton pulse
width.
- store the temporal information of the outcoming neutrons (for ex. in
a ntuple with all the informations you need...).
To do this I would suggest to use the mgdraw.f routine, which is
activated by the card USERDUMP with what(1) >=3D 100. There you can look
for neutrons, for example at the boundary crossing (subroutine
BXDRAW) between your moderator and the medium where you put it
(i.e. air or vacuum); in the include (TRACKR) you find the variable
Atrack, which is the age of the particle, always in seconds.
cheers,
Anna
