Quality Control Tests of ITK Pixel Modules — •Ruben Förster, Jörn Grosse-Knetter, and Arnulf Quadt — II. Physikalisches Institut, Georg-August-Universität Göttingen

The High Luminosity upgrade of the Large Hadron Collider (HL-LHC) presents significant challenges for the subcomponents of the ATLAS experiment. Consequently, it necessitates the construction of an all-silicon Inner Tracker (ITk) able to deal with increased particle fluxes and radiation levels.

ITk will feature both hybrid pixel and strip detectors, with the pixels forming the inner part. The ITk pixel detector will consist of about 10,000 separate modules, with approximately 600 of them expected to be processed at the University of Göttingen.

Performing Quality Control (QC) tests is vital to ensure the performance of the modules at the time of installation and during the promised 10 years of operation. The QC tests evaluate the overall functionality and electrical properties of the modules, as well as the performance of individual pixels. QC tests are conducted at different stages of the production process to ensure that the modules are within the specifications and that no damage has occurred during the previous assembly steps. As part of the preproduction phase, work has been undertaken to ensure the feasibility of performing QC tests while also automating and optimizing the processes to ensure that modules can be produced in a timely manner.
