The SAND detector at the DUNE near site.

DUNE is a next-generation experiment for long baseline neutrino physics. The near detector (ND) complex aims at constraining the systematic uncertainties to ensure high-precision measurements of neutrino oscillation parameters and $CP$ violation. 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 a mixture of lead and scintillating fibers. The inner magnetized volume is provided with a novel LAr detector and a low-density Straw Tube Tracker (STT). In this contribution the major components of SAND and their role in the measurements of (anti)neutrinos interactions are presented.
