Mechanical Construction and Liquid Handling System of the OSIRIS (Online Scintillator Internal Radioactivity Investigation System) Predetector Facility — •Hans Theodor Josef Steiger1, Lothar Oberauer1, Rainer Othegraven2, Mathias Walter1, and Michael Wurm2 for the JUNO collaboration — 1Physik Department der Technischen Universität München, James-Franck Straße 1, 85748 Garching bei München — 2Institut für Physik, Experimentelle Teilchen und Astroteilchenphysik, Johannes Gutenberg Universität Mainz, Staudinger Weg 7, 55128 Mainz
To ensure the liquid scintillator (LS) quality, necessary for a successful operation of the JUNO (Jiangmen Underground Neutrino Observatory) detector the OSIRIS system is currently designed. This 20 t detector serves as online monitor for the radiopurity of the scintillator produced during the commissioning and production phase of the LS purification plants. After the filling of the JUNO detector detailed studies of the LS characteristics are foreseen. This talk is focused on the mechanical design of the OSIRIS detector and the liquid handling system necessary for the screening of a significant fraction of the 6000l/h of LS produced in the purification plants. This work is supported by the DFG Clusters of Excellence "Universe" and "PRISMA", the DFG Research Unit "JUNO" and the Maier-Leibnitz-Laboratorium.
