Atmospheric neutrino spectrum reconstruction with JUNO

Understand

The atmospheric neutrino flux represents a continuous source that can be exploited to infer properties about Cosmic Rays and neutrino oscillation physics.

• The JUNO observatory, a 20 kt liquid scintillator currently under construction in China, will be able to detect atmospheric neutrinos , given the large fiducial volume and the excellent energy resolution.
• The light produced in neutrino interactions will be collected by a double-system of photosensors: about 18.000 20" PMTs and about 25.000 3" PMTs.
• The rock overburden above the experimental hall is around 700 m and the experiment is expected to complete construction in 2021.
