Description
The Jiangmen Underground Neutrino Observatory(JUNO) is a multi-purpose neutrino experiment, currently under construction in China. Its central detector is designed as a liquid scintillator detector of a 20kton fiducial mass with energy resolution of $3\%/\sqrt{E(MeV)}$, deployed in a laboratory 700 meters underground shielded by rock. Measuring the neutrino burst from the next nearby supernova is a premier target of low-energy neutrino physics and astrophysics. JUNO will also cooperate
with other neutrino detectors and be prepared to the next core-collapse supernova signal.
For a typical galactic distance of 10kpc and typical SN parameters, JUNO will register about 5000 events from IBD, $\bar{\nu}_{e}+p \rightarrow n+e^{+ }$, comparable to Super-Kamiokande,
about 2000 events from $\nu+p \rightarrow \nu+p$, more than 300 events from neutrino-electron scattering, as well as the charge current and neutral current interaction of neutrinos on the $^{12}C$ nuclei. Such a future high-statistical observations of neutrino burst will definitely help to extend the lessons from the SN 1987A to areas that depend on high statistics, good energy resolution, or flavor information, notably in the area of neutrino oscillations.
In this talk, we will cover the SN neutrino detection in the JUNO experiment and review the potential implications for both astrophysics and particle physics. As an example, we shall present our study to pin down the initial SN spectra using the unfolding method.
