Campuses:
Neutron capture multiplcicity distribution as measured by Borexino (red symbols) and compared to a quick/less detailed simulation with FLUKA. Both the time and energy cuts are applied individually (green: energy, blue: time) and combined (black).
The two graphs below were taken from the Borexino paper on cosmogenic backgrounds which also shows result from Geant4 (latest released version). HOWEVER, the carefully FLUKA prepared muon radiation field outside the Borexino detector was used as input for both FLUKA and Geant4 to then predict cosmogenic backgrounds in Borexino.
