The secondary pions and kaons produced at Fermilab's Booster Neutrino Beam decay to produce a neutrino beam with an average energy of around 800 MeV.
Notes on verification
Confirmed by multiple independent technical and peer-reviewed sources from Fermilab, MiniBooNE, and MicroBooNE collaborations, consistent with the ~788 MeV flux calculation rounding to about 800 MeV. [tier=silver indep_score=1.0 clusters=2 claim_tier=notable]
