Description
The Deep Underground Neutrino Experiment (DUNE) is a next-generation long-baseline experiment, hosted in the USA, that will precisely measure neutrino oscillation parameters, observe astrophysical neutrinos, and search for evidence of physics beyond the standard model. The experiment will consist of a near-site complex that will measure the neutrino flux from an accelerated particle beam produced at the LBNF (Long Baseline Neutrino Facility) at Fermilab, along with four Liquid Argon Time Projection Chamber detectors, with a total liquid argon mass of 70 kilotons, located 1300 km away and 1.5 km underground at the Sanford Underground Research Facility (SURF). The far-site modules are capable of detecting MeV-scale neutrinos from astrophysical sources and will offer unique sensitivity to electron neutrinos from a core-collapse supernova burst. This poster will cover recent progress on the detection and reconstruction of supernova burst neutrinos in DUNE, including the pointing capabilities essential to progenitor identification and coordination with other multi-messenger observatories. It will also consider the challenges involved into pushing DUNE’s detection threshold into the few-MeV regime. This is of interest not only for supernova neutrino detection, but also solar neutrino studies, including observations of the day/night asymmetry and probing the most-energetic (hep-chain) solar neutrino component, which has not yet been measured.
