    "abstract": "The Neutrinos at the Main Injector (NuMI) beamline will deliver an intense\nmuon neutrino beam by focusing a beam of mesons into a long evacuated decay\nvolume. We have built 4 arrays of ionization chambers to monitor the neutrino\nbeam direction and quality. The arrays are located at 4 stations downstream of\nthe decay volume, and measure the remnant hadron beam and tertiary muons\nproduced along with neutrinos in meson decays.",
