Working Toward a Precision Neutrino Beam

As the Deep Underground Neutrino Experiment nears construction, the existing neutrino facilities at Fermilab provide opportunities to test and refine methods characterizing high precision neutrino beams. MARGARITA is a water Cherenkov stopped muon detector that features twin photomultiplier tubes and two small, slightly differing detector volumes. The two detector volumes are designed to exploit the difference between the lifetimes of positive and negative muons in matter in order to characterize a neutrino beam. MARGARITA is currently being developed in the Neutrinos at the Main Injector (NuMI) beamline. The NuMI beamline also contains an existing muon monitoring system that has been underutilized. Improved analysis via ROOT and simulation via Geant4 of past, current, and future data from the muon monitors during an array of operating conditions could provide useful insights for any experiment at Fermilab utilizing a precision neutrino beam.
