Each station equipped with tracking detectors, inserted Pots which approach beams vertically. detectors consist multi-layer scintillating fibre structures read out Multi-Anode-Photo-Multipliers.
Abstract The CMS Phase-2 Outer Tracker requires the manufacturing of 8000 Strip-Strip and 5880 Pixel-Strip silicon modules, altogether incorporating 47 520 hybrid circuits 18 variants. To ensure complete functionality modules it is essential to perform production-scale testing hybrids before module assembly. For that reason, a complex, scalable test system was designed, manufactured, commissioned. However, deployment encountered more difficulties than anticipated which required extensive...
Abstract The CMS Tracker Phase-2 Upgrade requires the production of two co-planar strip sensor (2S) modules, and macro-pixel (PS) modules to cope with requirements HL-LHC. Altogether 47520 hybrid circuits are required construct 8000 2S 5880 PS modules. hybrids pre-production phase is now complete. A pre-series batch enabled identification different issues that were resolved completion pre-production. Various solutions reported.

One important consideration of the design and operation pixilated detector is ratio pixel size to thickness detector. When e-h pairs are generated charge drifts toward electrodes under influence bias field, spread directly related drift time, which strongly depends on carrier mobility distance travelled by carriers.
