Hi Noemi,
the IPROZ and IPROA variables take their value from the HI-PROPE card to
define the properties of a heavy ion beam, when you use the HEAVYION
particle as sdum in the BEAM card. The default values in HI-PROPE are
for the carbon ion Z=6, A=12. For all other particles including He-4,
He-3, T, D they are not used at all, since these ions are treated by
FLUKA in a special way.
I think the usermvax/source.f routine is almost self explanatory on what
to change.
If you want an ion beam, you have to set the IJBEAM to -2 (BEAM card
with sdum=HEAVYION) and then set accordingly the IPROA and IPROZ either
from the HI-PROPE card, or directly in the source.f routine in case you
want a distribution of different ions. For a normal hadron run including
(He-4,3, T, D) set the IJBEAM either by the BEAM card sdum, or directly
in the source.f routine, but in this case the Z,A are of no importance.
Regards
Vasilis

Subject: IPROA and IPROZ in SOURCE
Hi!
By using the routine SOURCE in order to generate events with a given
spectrum (I specified the particle type by means of BEAM in the input
file with SDUM=PROTON) I found that the variables IPROA and IPROZ
resulted equal 12 and 6 respectively while I expected IPROA=1 and
IPROZ=1 because I assumed that IPROA is the atomic mass number and IPROZ
is the atomic number of the incident particle. I found the same results
with alpha particles (BEAM in the input file with SDUM=4-HELIUM).
Therefore I would like to know the name of variables corresponding to
the incident particle atomic mass number A and to the atomic number Z in
SOURCE.
Thanks,
noemi
