Development of high reliability Powerboards for JUNO — •Florian Kiel, Achim Stahl, and Jochen Steinmann — 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. All neccessary electronics for the operation and readout of the PMT are mounted to the back of the PMT, creating an intelligent PMT.

One of the boards needed in this setup is a board to produce and distribute all voltages needed. The latest prototype version of this Powerboard fulfills all electronics requirements e.g. low ripple and high efficiency while having a very high reliability. As the electronics can not be accessed after mounted to the PMT a low failure rate is a condition.

In this contribution the Powerboard for an intelligent PMT will be introduced focusing on the reliability of the board.
