Dear Stefan,
I am indeed defining a Au beam with BEAM and HI-PROPE and use
DPMJET. Now how to make this Au ion beam collide another Au ion
(which will be at rest) using DPMJET ?=20
Another question , should i also define a Au target at a certain width
and reduce the interaction length in target material with LAM-BIAS
card in order to have 100% interaction target defined ?=20
thanks in advance=20

Dear Denis,
I am not sure if I understand correctly what you mean by "Fluka used as =
a
event generator". What you can do is defining a Au beam (with BEAM and
HI-PROPE cards) at the required energy and a Au target via the usual =
FLUKA
input. You then have to activate DPMJET via EVENTYPE/Sdum=3DDPMJET and =
run=20
like any other FLUKA run. This would be a fixed-target configuration =
(this=20
is what you want, correct?), not Au-Au collisions in the cm frame.
In each A-A collision (including Au-Au) DPMJET3 will create two excited
residual nuclei which are passed onto the FLUKA modules for evaporation,
fragmentation and deexcitation. All fragments are transported by FLUKA =
and
fed back to DPMJET (or RQMD at lower energies) in case of =
re-interactions.
Hope this answers your question(?)
Greetings
Stefan
