DUNE is a next-generation long baseline experiment for neutrino oscillation physics. The Near
Detector complex aims at constraining the systematic uncertainties to ensure high precision
measurements of neutrino oscillation parameters. The SAND apparatus is one of the three
components of the Near Detector complex permanently located on-axis to monitor the neutrino
beam stability, measure its flux and perform precise neutrino physics. SAND exploits a 0.6 T
superconducting magnet coupled with an electromagnetic calorimeter made of lead scintillating
fibers. The inner magnetized volume is provided with a novel LAr detector and a low-density
Straw Tube Target tracker. In this article the major components of the SAND apparatus and their
role in the measurements of (anti)neutrinos interactions are presented.
