Description
The Short-Baseline Near Detector (SBND) is a 112-ton active volume Liquid Argon Time Projection Chamber (LArTPC) neutrino detector which sits just off-axis from the Booster Neutrino Beam (BNB) at Fermilab. It is the near detector of the Short Baseline Neutrino (SBN) program, which is comprised of three LArTPC detectors in total. The main focus of the program is studying sterile neutrino oscillations with much greater statistics capabilities than have been previously possible.
The PRISM concept exploits the relation between the off-axis angle of the beam and the flux energy spectrum; moving off-axis from the beam centre results in the spectrum of neutrino energies peaking at lower energies. Therefore, by combining measurements at different beam off-axis angles it is possible to reduce neutrino interaction uncertainties. SBND is ideal to exploit the PRISM technique as it sits only 110 m from the target, hence is exposed to a range of off-axis angles (0- 1.6°). The work presented here will focus on oscillation measurements within the SBND-PRISM framework and how treating SBND as multiple detectors at varying off-axis angles leads to an improvement in expected sensitivity.
