Transverse momentum discriminating silicon modules for the Phase-II Upgrade of the CMS Outer Tracker

The Large Hadron Collider (LHC) will undergo a major High Luminosity upgrade with the goal of delivering a peak instantaneous luminosity of about 5−7.5 × 1034cm−2s−1 by 2027. In order for the CMS experiment to cope with the higher radiation levels and data rates, the current CMS Silicon Outer Tracker will be replaced. The upgraded Outer Tracker will introduce a new module concept, made of two vertically stacked silicon sensors, which will exploit the strong magnetic field inside the CMS detector to select high transverse momentum particles locally and send the corresponding information to the triggering system.This talk will focus on one of the two foreseen designs, the Pixel-Strip (PS) module, as well as the developments related to the module assembly and testing, covering the topics of momentum discriminating module design, DAQ system and automated assembly
