The MicroBooNE Continuous Readout Stream for the Detection of Supernova Core-collapse Neutrinos

MicroBooNE is a liquid argon time projection chamber (LArTPC) neutrino experiment located on the Booster Neutrino Beamline (BNB) at Fermilab. MicroBooNE's primary research goals involve the study of BNB neutrinos and their interactions on argon. Its secondary goals involve astro-particle and exotic physics searches. Specifically, MicroBooNE is the first large-scale LArTPC operating with a continuous readout data stream dedicated to detecting neutrinos from a core-collapse supernova. To do so, MicroBooNE relies on an external SuperNova Early Warning System (SNEWS) alert, which comes with a latency on the order of hours, and prompts permanent storage of continuous readout data, otherwise written on a circular disk buffer. This talk will present the MicroBooNE continuous readout data stream, and studies performed to validate its successful operation and sensitivity to low-energy signatures consistent with supernova neutrino interactions in LArTPCs.
