The Phase-2 upgrades for the ATLAS and CMS detectors are the next big upgrade projects imminent. To cope with the challenging conditions for High Luminosity LHC (HL-LHC), the current trackers for both experiments will be replaced by new sub-detectors: the ATLAS Inner Tracker (ITk) and the CMS Tracker. The all-silicon detectors are segmented in the inner regions by the ITk Pixel and the CMS...

The Tracker Barrel with 2S Modules (TB2S) detector of the HL-LHC CMS Tracker will consist of 4416 silicon strip modules, supported by 368 “Ladder” structures. A carbon composite “Wheel” of 2.4 m diameter and 2.4 m length supports the Ladders as well as smaller sub-detectors of the Tracker. This presentation summarizes the main design features of the TB2S Wheel and explains the various...

During the LHC Phase 2 upgrade, the CMS Tracker will be upgraded to meet the performance demands of High-Luminosity LHC (HL-LHC). This presentation focuses on the realisation and technical decisions of the Tracker Barrel Pixel (TBPX), which has recently reached production phase. To start, it will be presented the current status of the prototypes and first final layers produced, followed by an...

For the High Luminosity LHC (HL-LHC), the CMS is going to operate at up to 200 interactions per 25 $ns$ beam crossing and reaching up to 4000 $fb^{−1}$ of integrated luminosity. The CMS Tracker Phase-2 upgrade for the HL-LHC requires designing new Inner and Outer Tracker (OT) systems to cope with the increased luminosity, to ensure excellent tracking performance in the presence of a high level...

The Phase II upgrade of the Compact Muon Solenoid (CMS) detector includes major advancements in composite structures and thermal interface design. Following successful prototyping and validation, production of the Inner Tracker Support Tube (ITST) has begun. This presentation highlights key lessons learned and milestones achieved during the production of the ITST composite structures,...

The Barrel Timing Layer and Tracker Support Tube (BTST) is a 2.4-meter diameter, 5.3-meter long composite sandwich structure designed to provide primary mechanical support for the Barrel Timing Layer, Outer Tracker, and Inner Tracker detectors of the CMS detector for the HL-LHC. This presentation provides updates on repair campaign at CERN, simulation learnings and repair validation testing...

As part of the CMS Phase-2 Upgrade project, a novel detector, the Endcap timing Layer (ETL), will be installed during LS3 with the goal of precisely measuring the production time of minimum ionizing particles (MIPs) during HL-LHC era which comes with increased number of collisions. To ensure optimal operating conditions, a two-phase CO2 cooling system is going to be used to extract the heat...

During Long Shutdown 3, the Large Hadron Collider (LHC) at CERN will undergo an upgrade program, marking the beginning of the High-Luminosity era. The High-Luminosity Large Hadron Collider (HL-LHC) is expected to collide protons at a centre-of-mass energy of 14 TeV and to reach the unprecedented peak instantaneous luminosity of 7 x 10^34 cm^-2 s^-1 with the average number of pileup events...
