DUNE is a next-generation of long baseline experiment for neutrino oscillation physics. The near detector (ND) 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 ND permanently located on-axis to monitor the neutrino beam stability and measure its flux. SAND exploits a 0.6 T superconducting magnet coupled with an electromagnetic calorimeter made of lead scintillating fibers. The inner magnetize volume is provided with a novel LAr detector and a low-density Straw Tube Tracker (STT). In this poster the major components of SAND and their role in the measurements of (anti)neutrinos interactions are presented.
