Monitoring Systems for the Filling of the Central Detector of JUNO — •Hans Steiger, Lothar Oberauer, Andreas Ulrich, Philipp Landgraf, Sabrina Prummer, Julia Sawatzki, and Mario Schwarz — Technische Universität München, Physik Department, Lehrstuhl für experimentelle Astroteilchenphysik, James-Franck-Str. 1, 85748 Garching bei München

In the planned JUNO (Jinangmen Underground Neutrino Observatory) Detector 20 kt of liquid scintillator (LS) will be used as neutrino target. A 120 mm thin highly transparent acrylic hollow sphere stores the target in a water tank. Slightly different filling levels in the tank and the sphere during the filling of these volumes could cause fatal damage of the detector. Therefore precise monitoring of the hydrostatic and gas pressure in both volumes as well as controling the mechanical stress on the acrylic is necessary. Also the filling levels in the water tank and the sphere has to be monitored. For this tasks first concepts and developements carried out in Munich are presented in this talk. This work is supported by the DFG Cluster of Excellence "Origin and Structure of the Universe", the DFG research unit "JUNO" and the Maier-Leibniz-Laboratorium.
