Description
An upgrade program is planned for the LHC to increase the instantaneous luminosity up to 5x10^34 /cm^2/s to reach an integrated luminosity of 3000/fb. The CMS experiment will be equipped with an entire new tracking detector in the so-called Phase-2 Upgrade, when LHC will reach the high luminosity phase, HL-LHC. The new tracking detector must be able to fully exploit the demanding operation condition with a high number of pile-up events, withstand 1.5x10^15 n_eq/cm^2 and in addition will have the capability to deliver Level-1 trigger information. The poster shows the concept of so-called 2S modules of the Outer Tracker with two close-by silicon strips sensors able to discriminate high p_t particles from low p_t particles already on module level. The detector components will be described and the necessary production steps and quality checks during the construction phase will be shown.
