MaPSA quality control for the CMS phase-II detector upgrade

The Phase-II upgrade of the CMS detector aims to equip the outer tracker with new silicon sensor modules to handle the increased luminosity of the LHC. These modules integrate strip and pixel layers to enable precise position measurements, which will be placed in the inner layers of the outer tracker. The pixelated silicon sensor layer, paired with its readout chips, forms the macro-pixel sub-assembly (MaPSA). This presentation discusses the quality control procedures performed at DESY by the CMS Phase-II Tracker Upgrade group in Hamburg.
