FLUKA uncertainty

Dear experts,

we use FLUKA as main simulation program. We need to cite the intrinsic uncertainty of this MC in a typical full containment calorimeter simulation when basically all the cross-sections come into the scenario of secondary particle production. We have found papers where doses and ionization losses were compared to experimental data, however we would need an overall average uncertainty performance. We are aware that it would be particle, energy and material dependent, it is probably of the order of 10%, but we would really appreciate if you could indicate an appropriate reference.
Thank you so very much in advance.

Dear @michele,
yours is certainly a relevant question, although the answer is not really straightforward, as you anticipated. In short, I’d tend to agree with your rough order of 10% quantification, still depending on the accuracy of your geometry and material description, and as an example I’d refer you to the case of the LHC ionization chambers, which measure absorbed doses around the accelerator as a result of complex hadronic and electromagnetic particle shower development through the massive elements (especially magnets) of the beam line. In this regard, several benchmark studies were reported in the rather recent Phys. Rev. Accel. Beams paper Validation of energy deposition simulations for proton and heavy ion losses in the CERN Large Hadron Collider.

Dear Francesco,
thank you very much for your kind reply which is very useful for us.
Best regards,
Michele
