Advanced Powering of Pixel and Tracking Detectors — •Martin Lipinski — I. Physikalisches Institut B, RWTH Aachen University, Germany

Modern pixel and tracking detectors like the ones foreseen in the upgrades of the LHC experiments require novel power systems. On the one hand, an increasing number of active channels as well as higher data rates lead to a larger power consumption of the detectors. On the other hand, the supply voltages must decrease due to smaller technology nodes used for the frontend electronics. Advanced powering schemes are required to avoid large cable losses and to keep the material budget small.

In this talk, two different powering concepts, based on DC-DC conversion and based on serial powering, will be discussed. The implementation of both schemes in the future Phase-2 upgrades of the ATLAS and CMS silicon tracking detectors will be presented. In addition, the experience gained from the use of DC-DC converters in the CMS Phase-1 pixel detector will be reported.
