Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kton liquid scintillator detector designed to determine the neutrino mass ordering and perform precision measurements of neutrino oscillation parameters. Beyond reactor neutrinos, JUNO’s unprecedented scale and energy resolution offer unique opportunities for multi-messenger astronomy, particularly in detecting core-collapse supernova (CCSN) bursts and other transient astrophysical phenomena.
To fully exploit these opportunities, a dedicated Multi-messenger (MM) trigger system has been developed, consisting of a low-energy threshold trigger and a transient neutrino burst monitor. The low-threshold trigger utilizes a fast, likelihood-based algorithm implemented on FPGA-based hardware, enabling strong suppression of dark noise and radioactive backgrounds. Based on the MM trigger, the transient neutrino burst monitor identifies statistically significant rate enhancements of neutrino candidate event rates across a wide energy range. It provides highly efficient, low-latency transient source detection, where the expected performance for CCSN detection is presented here.
