On Jan. 25, the Booster delivered a record 5 x 1012 protons per pulse at 5 Hz for half an hour while delivering 8.3-Hz beam to Recycler. The protons in the beam strike a target, and the resulting particles decay into neutrinos. The high-intensity proton beam translates into the highest-intensity neutrino beam sent down the Booster Neutrino Beamline (BNB) in its history.
BNB provides beam to MicroBooNE and several other small experiments and is the future home of the Short Baseline Neutrino experiments.
As a result of the Proton Improvement Plan, the Proton Source is now fully capable of 15-Hz operation, which will enable NOvA, the BNB experiments and the future Muon Campus experiments to run concurrently. Strategic efforts to improve beam delivery and reduce losses have additionally allowed increases in intensity to BNB.
