Gas Cherenkov Muon Detector

The future Deep Underground Neutrino Experiment will shoot a neutrino beam 1,300 km from Fermilab in Illinois to a detector in South Dakota to better understand neutrino properties.~ The beam is created by the decay of pions into neutrinos and muons.~ Therefore, by analyzing muons one can infer information about the neutrinos.~ This talk will focus on measuring the muon distribution at the beginning of the beam with the goal of constraining the associated neutrino beam.~ This is done by measuring Cherenkov radiation from muons passing through a detector filled with argon gas. There is a prototype detector at Fermilab in the NuMI beamline that makes these measurements. A muon distribution is approximated by observing and analyzing these signals over various gas pressures and detector orientations.~ This model, whose input is a signal and output a muon distribution, is built using computer simulations.~ I will discuss how such a model is created and how to go about comparing the simulations with real data. \newline
