The conventional PMT system for OSIRISFeng Gao, Florian Kiel, •Tim Kuhlbusch, Achim Stahl, Jochen Steinmann, Christopher Wiebusch, and Christian Wysotzki — III. Physikalisches Institut B, RWTH Aachen

The 20-ton OSIRIS detector is designed to measure radiopurity and quality of the liquid scintillator for JUNO. This is especially necessary to commission the liquid handling and purification systems. OSIRIS will monitor the scintillator quality during the filling to ensure that JUNO reaches the design sensitivity. After filling of the central detector OSIRIS can be used for detailed studies of scintillator characteristics and monitoring. OSIRIS will harness two PMT systems: One is the novel iPMT system where each PMT is equipped with an intelligent readout electronic at the back. By reusing parts of the trigger system, FADCs, PMTs and Front End Electronics (FEE) from Double Chooz, the conventional PMT system is based on a reliable and well tested system. Due to the needs of OSIRIS the readout scheme is adapted to enable online reconstruction and to integrate the iPMT system.
