Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation neutrino oscillation long-baseline experiment designed to measure the neutrino mass ordering, the CP-violating phase in the lepton sector of the Standard Model and to improve the precision on key parameters that govern neutrino oscillations. The System for on-Axis Neutrino Detection (SAND) at the DUNE Near Detector complex is designed to monitor the beam on-axis, control systematic uncertainties for the oscillation analysis, precisely measure neutrino cross sections, and perform short-baseline neutrino physics studies.
SAND will exploit the existing KLOE electromagnetic calorimeter made of alternating lead/scintillating fiber layers that will work with a 0.6 T superconducting magnet, both refurbished from the KLOE experiment. The Straw Target Tracker (STT) occupies most of the internal volume. It is composed of alternating planes of thin graphite/polymer targets and straw tube planes, providing multiple nuclear targets for the measurement of $\nu$-p and $\nu$-C cross-sections. A 1-ton active target for the $\nu$ -Ar interactions, called GRAIN, is located in front of the STT and is designed to image neutrino interactions using scintillation light produced in Ar by charged particles. In this talk, the current status of the detector and its performance will be discussed.
