Description
Fermilab hosts the world's most powerful neutrino beam facility, Neutrinos at the Main Injector (NuMI) and the future Long Baseline Neutrino Facility (LBNF) at Fermilab, which will be even more powerful. The sensitivities of the long-baseline neutrino oscillation experiments that use these beams require precise alignment and monitoring of the beam in a high radiation environment over long periods. We propose new stable, radiation-hard beam monitors to measure the profile of hadrons downstream of the neutrino production target and muons after the hadron absorber. We present the status of the R&D for improvements to the current ionization chambers used in the NuMI beamline, and R&D for a future radio-frequency-based detector which measures a gas permittivity shift due to ionization in a gas-filled resonator. We also present the status of the development of a new machine-learning-based algorithm to constrain the systematic uncertainty of the neutrino flux due to the beam instability using the data from these detectors.
