Description
The Deep Underground Neutrino Experiment (DUNE) is based on a wide-band, intense neutrino beam from Fermilab, a far detector of large liquid argon time projection chambers, and a near detector to characterize the beam and constrain systematic uncertainties. The System for on-Axis Neutrino Detection (SAND) will be part of the DUNE near detector. It is based on a superconducting magnet (0.6T) and an electromagnetic calorimeter (ECAL), repurposed from the KLOE (K-Long Experiment) experiment. The ECAL is a lead-scintillating fiber sampling calorimeter of total thickness of about 15 $X_0$, consisting of a cylindrical barrel section and two endcaps. The energy resolution is $\sigma / E = 5\%/\sqrt{E(GeV)}$ and the timing resolution is $54/\sqrt{E(GeV)}$ ps $\oplus$ 50ps. The ECAL provides particle identification and and reconstruction of $e^\pm, \gamma$, $\pi^0$ and neutrons. The upstream barrel ECAL can be used as an additional active target system with a total fiducial mass of 22.8 tons.
