Dear Users,=20
I have the following experiment to simulate :=20
Projectile : A gold beam particle at 25 GeV/nucleons
Fixed target: 1% interaction Au target (corresponds ~ 250 micrometers )
Iron beam dump at the end of the cave.=20
=20
Now i would like to study the fluences of electron, protons, pions and =
mostly neutrons
inside the cave.
For minimum bias event i use Fluka heavy ion definition with DpmJetIII. =
For Au-Au collision i use a external source ( using source.f ) reading =
UqQmd output
file and filling the stack.
Now i want to estimate the fluence of all particles in the cave.
My question is how to modify source.f in order to have the correct =
normalization for the fluence?
In source.f there is the line calculating total weight for primaries:
=20
WEIPRI =3D WEIPRI + WTFLKA( NPFLKA )
=20
should i modify it to=20
=20
WEIPRI =3D 1/100 ?
thanks in advance=20
