    "abstract": "The Neutrinos at the Main Injector (NuMI) facility is a conventional neutrino\nbeam which produces muon neutrinos by focusing a beam of mesons into a long\nevacuated decay volume. We have built four arrays of ionization chambers to\nmonitor the position and intensity of the hadron and muon beams associated with\nneutrino production at locations downstream of the decay volume. This article\ndescribes the chambers\u0027 construction, calibration, and commissioning in the\nbeam.",
