Description
DUNE is a next-generation long-baseline neutrino experiment designed to measure all parameters governing neutrino oscillations within a single experimental framework. Achieving the precision required for these measurements demands stringent control of statistical uncertainties, which will be provided by a multi-component Near Detector (ND) complex.
The System for on-Axis Neutrino Detection (SAND) is one of the detectors comprising the ND. It will be permanently located on axis, with the primary objectives of monitoring the neutrino beam and measuring the neutrino flux. In addition, precise control of the configuration, chemical composition, and mass of the (anti)neutrino targets in SAND enables high-statistics measurements of (anti)neutrino interactions on hydrogen and other nuclear targets, including argon. The hydrogen interaction sample, specifically, can be obtained through statistical subtraction, exploiting data collected with alternating plastic and pure carbon targets.
This talk presents the SAND detector design and its physics program, and describes a proof-of-concept study exploiting the statistical subtraction method.
