Development of intelligent Photomultipliers — Florian Kiel, •Jochen Steinmann, and Achim Stahl — III. Physikalisches Institut B, RWTH Aachen University

For the next generation of large neutrino detectors, for example JUNO, a novel concept for the readout of the Photomultiplier-Tubes has been developed. The idea is to build an intelligent PMT, which has all neccessary electronics mounted at the back of the PMT. This electronics is able to digitise and analyse the measured data, using the VULCAN-ASIC designed by the FZ-Jülich and an FPGA. Due to the high computing power of the selected FPGA the electronics is even able to do a low level waveform reconstruction. Based on the analysed data, the operational parameters of the PMT, e.g. applied voltage, can be regulated autonomous. Since the PMT will be connected via digital signals only, the performance does not decrease with long analog cables. This concept can be easily adapted from the laboratory to any size of detector. A first demonstration will be done using a 20" Hamamatsu PMT. In this contribution the concept and the road to the first prototype will be presented.
