An On-line Attenuation lenght Monitor for JUNO — •Heike Enzann for the JUNO collaboration — Johannes Gutenberg-Unversität, Ec Prisma, Mainz, Deutschland
The Jiangmen Underground Neutrino Observatory (JUNO) with its 20 kt liquid scintillator (LS) detector is designed to determine the neutrino mass hierarchy via a precise survival probability measurement of reactor antineutrinos. It is currently under construction in China and will start data taking in 2020.
To reach the required measurement precision, high optical purity of the LS is necessary . This talk covers the development and testing of an on-line attenuation length monitor for LS quality control. The device will be installed as part of the filling system to monitor the purity of each LS batch before it is inserted into the central detector via a measurement of the attenuation length. This work is supported by DFG research unit "JUNO".
