Monitoring of the DUNE long baseline neutrino beam with SAND detector

The Deep Underground Neutrino Experiment (DUNE) will be a next generation neutrino oscillation long baseline accelerator experiment. It will be composed of a Near Detector (ND) system located a few hundred meters from the neutrino source at Fermilab, and a Far Detector (FD) system composed of three multi-kiloton LArTPCs. Of the three Near Detectors, SAND (System for on-Axis Neutrino Detection) will have as its main purpose to provide constraints on all the systematic uncertainties relevant for the oscillation analysis. Among these, one of the detector's main task will be beam monitoring which consists in using the flux measurements to spot potential anomalies in the beam production. This thesis studies the beam monitoring capabilities of the SAND detector, via neutrino flux and detector simulations.
