Abstract:
The Neutrinos at the Main Injector (NuMI) beamline will deliver an intense muon
neutrino beam by focusing a beam of mesons into a long evacuated decay volume. The
beam must be steered with 1 mRad angular accuracy toward the Soudan Underground
Laboratory in northern Minnesota. We have built 4 arrays of ionization chambers to
monitor the neutrino beam direction and quality. The arrays are located at 4 stations
downstream of the decay volume, and measure the remnant hadron beam and tertiary
muons produced along with neutrinos in meson decays. We review how the monitors
will be used to make beam quality measurements, and as well we review chamber
construction details, radiation damage testing, calibration, and test beam results.
