Triggering on Supernova Burst Neutrinos at DUNE

Liquid Argon Time Projection Chambers (LArTPCs) are sensitive to low energy electron neutrinos via a charged current interaction on argon. The Deep Underground Neutrino Experiment’s (DUNE’s) 40kt far detector at the Homestake mine in South Dakota will therefore offer a unique opportunity to study supernova neutrinos. The detection of galactic supernova burst neutrinos, a primary physics goal of DUNE, requires a data acquisition system capable of triggering the readout of a data stream of order 1TB/sec/10kt for 10s of seconds. Supernova bursts offer a unique signature on which to trigger. This poster describes the potential for and development of a real-time trigger based on simple primitives, designed to be issued in the presence of such supernova bursts.
