Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation experiment designed to achieve unprecedented precision in the study of neutrino flavour oscillations. To minimize systematic uncertainties associated with neutrino flux predictions and interaction cross-sections, DUNE will utilize a sophisticated near detector (ND) complex. Among its three ND subsystems, the System for On-Axis Neutrino Detection (SAND) is positioned permanently on-axis to continuously monitor the beam. SAND integrates a 0.6 T superconducting magnet and an electromagnetic calorimeter composed of lead–scintillating fibres. Its core volume accommodates an innovative liquid argon (LAr) detector and a low-density tracker. A major objective of SAND is to constrain uncertainties in neutrino interactions, where nuclear effects play a critical role. By employing adjustable CH₂ and carbon (C) slabs, SAND enables the statistical subtraction of nuclear contributions, effectively creating a solid hydrogen target. This approach and its potential to enhance systematic precision in DUNE will be presented, as well as a general overview of SAND's capabilities and physics program.
