Multi-messenger and Low-threshold Trigger System at JUNO

Not scheduled


Prof. Donglian Xu (Tsung-Dao Lee Institute)


With 20-kiloton liquid scintillator as detection medium, the Jiangmen Underground Neutrino Observatory (JUNO) will have highly competitive sensitivity to MeV-scale neutrino, and will play an important role in the emerging field of multi-messenger astronomy, especially for the transient events where high radioactivity background can be easily bypassed. We will present a multi-messenger trigger system, which is built on novel hardware/firmware and lowers the detector trigger threshold by an order of magnitude -- to as low as 20 keV. This trigger system will enable the widest broadband real-time monitoring of the transient neutrino sky and possibly steady signal searches at the sub-MeV to GeV energies, and can communicate with other multi-messenger facilities around the world on the millisecond time scale.
