Overview on current state of the art Pixel Mechanics for the upgrade tracking detectors at the ATLAS and CMS experiments

In the high-luminosity era of the Large Hadron Collider, the instantaneous luminosity is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the ATLAS and CMS Inner Detectors will be replaced by all-silicon systems. Large silicon detector systems are foreseen to be installed. This brings several challenges on precision mechanics with low radiation lengths and high thermal conductivity. The presentation will give details on the mechanics designs of the upgrade trackers. The design principles will be shown with examples realized in prototyping. Measurements and results of design qualification will be presented. The integration and installation sequences will be described in addition with a focus on the required tools and required design features to build state-of the art tracking detectors
