Development of intelligent Photomultipliers for the JUNO Detector — •Florian Lenz, Jochen Steinmann, and Achim Stahl — III Physikalisches Institut B

The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose neutrino experiment currently build next to Jiangmen (China) with the primary goal to measure the neutrino mass hierarchy. The 20-thousand-ton liquid scintillator detector is therefore build 50km away from two nuclear power plants in South China. Due to the size of the detector it was decided to use a new concept for the readout - a fast ADC combined with a FPGA for a low-level reconstruction mounted on the base will convert the PMTs into intelligent sensors. The design and the functionality of the iPMTs will be explained with a focus on the power supply and challenges during the design.
