Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kiloton liquid scintillator detector with the capability to detect neutrinos from the next Core-Collapse Supernova (CCSN) and effectively manage the resulting large statistics. The real-time CCSN monitoring system of JUNO is designed to provide fast and reliable alerts by tracking the increasing event rates of supernova burst neutrinos and pre-supernova
neutrinos. The system comprises a prompt monitor at the CTU stage, an online monitor at the DAQ stage, and a multi-messenger monitor based on low-threshold triggers, ensuring second-level alert generation while maintaining full coverage of the Milky Way, with a false alert rate kept below one per month. Upon detecting an alert, the system will record as much data as possible for rapid analysis, facilitating multi
messenger observations of CCSN events. The monitoring system is officially online and connected to SNEWS 2.0. This talk will discuss the implementation and current operational status of the CCSN monitoring system, as well as evaluate its alert performance through simulations.
