Dear Agnieska,
I assume you refer to the use of SPECSOUR for pp collision.
In that case, for each new primary history (whose maximum number is given by the START card, WHAT(1)),
a new pp collision is generated (via a call to DPMJET, so do not forget to link it!)
and all “secondary particles” are loaded into the stack to be transported (but not the primary protons).
A primary history corresponds to a single pp collision, or better to the whole list of “secondary particles” produced in that pp collision,
and all results are normalised per pp collision.
Hope this could clarify the terminology issue.
Kind regards, luigi

> I’m using Fluka for simulation fluence of particle coming from proton-proton collisions at LHC energies. My question is: what is the meaning of “primary” in case of special source like pp? In HEP we consider “primary interaction” as the proton-proton interaction and particles produced are called “secondary particles”. Is the scoring of Fluka given per one proton-proton interaction? It would be great but I started to suspect that this is not the case.

At this energies there are huge amounts of pions, protons, neutrons, kaons or photons produced. Are they called “primaries”? So what Fluka means when in the scoring I get infos normalized to one primary?
