Dear Tom,
I believe the most advanced way to do this, is to customise the mgdraw.f routine to dump all the information (coordinates, energy, Z, A etc.) of the generated particles and then post process them however you want. However, the drawback is that it requires some expertise in the FLUKA subroutines.
You can check the respective fluka course slides to get started.

Alternatively, splitting the regions into many small ones could be a solution. I would suggest that you go through the USRYIELD card that gives you some extra versatility in scoring and can be combine with AUXSCORE for some extra refining.
Hope this helps
kind regards

Subject: [fluka-discuss]: Detailed scoring of r- and z-dependent energy spectra
Dear Fluka experts,
I’m doing simulations of Carbon beams of energies between ca. 70 and 450 MeV/u in water. I want to do the following:
* I want to score energy spectra of all elements up until Z = 8.
* I am interested in all isotopes of each chemical element, but I would like to group them by their atomic number, therefore I want to score the Energy/u spectra. (This is currently possible by multiplying the energy spectrum of each isotope by its mass and then summing the resulting spectra.)
* I would like the energy spectra in small volumes as a function of the both the depth (z for a beam in the z direction) and the distance from the beam axis (r).
As I currently understand I would need to divide my target region into a lot of small subregions and then in each region score the energy spectrum of each isotope. This will lead to a very(!) large amount of USRTRACK scoring cards. Also, if I exceed limit on the number of usrtrack scoring cards I would have to do multiple simulations of the same system to extract all the information I want.
Do you think USRTRACK is a viable option to get what I need? If not, what would you recommend doing instead?
Kind regards,
Tom
