Dear FLUKA developers,
For the sake of my ZDC studies, I am very interested in obtaining the description of the spectators in HI collisions provided by DPMJET + FLUKA. My goal would be to generate Heavy Ion collisions and then propagate to the ZDC all the spectator neutrons ( discarding spectator protons and fragments, since the magnets in the LHC would wipe most of them off ) in our Geant4 simulations.
In order to do this, I can imagine two different solutions:
- Use DPMJET within FLUKA, setting up a simulation in collider mode w/ HI and trying to dump all the produced particles outcoming from the collision point (e.g. using a small cylinder built around it as a dump surface). Then feed the output to our Geant4 simulation.
- Use DPMJET + FLUKA libraries as a standalone generator - to produce output files to be fed to our Geant4 simulation (or directly embedding the generator into the simulation).
From a practical point of view, 2) would be preferable, but I fear I have not enough experience w/ FORTRAN to establish the bundle. May I ask you if you know whether such a DPMJET+FLUKA package exists already? I found something on the web done for EIC, from ~ 10 years ago, but it was w/an old DPMJET version. I successfully compiled it vs the latest FLUKA release, but I did not manage to run it successfully (all the examples were crashing w/ a core dump).
If this kind of package does not exist and trying to build it would be too time expensive, may I ask you if solution 1) sounds reasonable to you?
Thanks in advance for your help,
Best regards,
Riccardo
