Abstract
English
The upgrade of the Large Hadron Collider to the High Luminosity Large Hadron Collider starting in 2024 will allow the experiments to collect approximately ten times more data for precision measurements of Standard Model processes and searches for new physics. The increase in luminosity poses challenges in terms of radiation hardness and detector readout. The ATLAS experiment will replace the current tracking detector with the new Inner Tracker (ITk) to cope with these challenges, which in particular includes the development of a new generation of readout chips. The Outer Barrel Demonstrator is a prototype stave in the context of the ITk pixel upgrade, but is still equipped with the legacy readout chip. This thesis is focused on the readout of the Outer Barrel Demonstrator. A new readout scheme for the demonstrator is developed and implemented and extensive tests and measurements are performed on the demonstrator and presented here.
