Development of an attenuation length monitor for JUNO — •Heike Enzmann, Michael Wurm, Wilfried Depnering, Paul Hackspacher, Oliver Pilarczyk, Artur Meinusch, Kai Loo, Hans Steiger, and Eric Theisen — Johannes Gutenberg - Universität, Institute of Physics, Mainz, Germany

The Jiangmen Underground Neutrino Observatory (JUNO) is currently under construction in China. Its 20 kt liquid scintillator (LS) detector is designed to determine the neutrino mass hierarchy via a precision measurement of the survival probabilities of electron anti-neutrinos in reactor neutrino oscillations. The filling of the detector with LS will commence late in 2021.

Excellent transparency of the LS is required to maximize the collection of scintillation light in order to reach the required measurement precision. Thus, several purity monitors will be installed as part of the filling system to test each batch of LS prior to its insertion into the Central Detector. This talk covers the development and testing of an attenuation length monitor for LS quality control. The monitor will measure the attenuation length using a laser. The measurement will be done over two different lengths of LS to reduce systematic effects. This work is supported by DFG research unit "JUNO" (FOR2319) and the Cluster of Excellence PRISMA+.
