Description

The TAO (Taishan Antineutrino Observatory) near detector of the JUNO (Jiangmen Underground Neutrino Observatory) neutrino experiment is a ton-level high energy resolution liquid scintillator (LS) Gadolinium-based detector. It will be located at a distance of about 30 - 35 m from the 4.6 GW core of the Taishan Nuclear Power Plant (NPP), China. The main goal of TAO will be the measurement of the reactor neutrinos spectrum via the Inverse Beta Decay (IBD) to detect the anti- neutrinos generated in the core of the NPP. In order to achieve its goal, the TAO experiment will be equipped with about 10 m2 surface of SiPMs (~ 95% coverage) working at -50° C to lower the dark noise. In this conditions the expected dark counts rate is about 100 Hz/mm2 with a Photo-Detection Efficiency (PDE) better than 50%. In this talk we will report on the performances of the SiPMs operated at low temperature for the JUNO - TAO detector, down to about -70° C. The test are running at INFN - Roma Tre, Italy
