Description

The System for on-Axis Neutrino Detection (SAND) within the ND complex of the Deep Underground Neutrino Experiment (DUNE) will monitor the neutrino beam. It consists of a superconducting iron magnet, a lead/scintillating fiber electromagnetic calorimeter (ECAL), and an inner tracking system. We studied a configuration with the inner magnetic volume filled with an active LAr meniscus, with polypropylene or graphite targets interleaved with planes of horizontal and vertical straw tubes (STT). Most of the sensitivity for the beam monitoring with SAND is provided by the upstream barrel ECAL. Interactions in the STT volume and in the LAr meniscus provide additional statistics. SAND has a sensitivity $\Delta \chi^2 \geq 9$ in one week of data taking for the variation of most of the relevant parameters affecting the beam systematics. A similar sensitivity is obtained for a change in the beam direction of about 0.13 mrad by combining the ECAL and STT.
