Abstract
One of the main challenges for the ATLAS ITk Phase II Pixel upgrade is low-mass efficient power distribution for detector modules. This requires a powering scheme alternative to the parallel (direct) powering which is currently used. A serial powering scheme has been chosen as the baseline for the ITk pixel system. A serially powered pixel detector prototype has been built with all the components that are needed for current distribution, data transmission, bypassing and redundancy in order to prove the feasibility of implementing serial powering scheme in the ITk. Detailed investigations of the electrical performance of the detector prototype equipped with FE-I4 quad modules have been made with the help of the USBpix3 readout system that has been developed in Bonn.Pubblicazioni consigliate
