The OSIRIS pre-detector - A radioactivity monitor for the JUNO liquid scintillator — •Paul Christian Hackspacher and Michael Wurm for the JUNO collaboration — Johannes Gutenberg-Universität Mainz

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20 kt liquid scintillator reactor neutrino experiment currently being built in the Guangdong province in southern China. In order to reliably reconstruct neutrino-induced inverse beta decay events from photomultiplier signals, scintillator purity is imperative. Potential air leaks in the filling and cycling lines or failures of the purification plants are risks that endanger the high radiopurity necessary to obtain clean signals within such a large active target volume. The Online Scintillator Internal Radioactivity Investigation System (OSIRIS) is being developed as a failsafe monitor to assess the quality of the scintillator batches before filling them into the central detector. This presentation will serve as a general introduction to the project concept, design and schedule, with more details on software and hardware shown in their own respective talks. This work is supported by the DFG Research Unit ``JUNO''.
