Description
The mechanical design of the CMS Phase-2 tracker addresses the stringent requirements of the HL-LHC environment, including stability under high radiation and thermal loads, minimal material budget, and precise alignment over large detector volumes. This talk details the engineering challenges and solutions behind the mechanical architecture of both the Inner Tracker (IT) and Outer Tracker (OT). Key topics include support structures, thermal management systems, carbon-fiber components, and the modularity enabling efficient assembly and maintenance. We present the integration strategy from substructures to full tracker systems, along with results from mechanical tests, thermal cycling, and alignment validation. The current status of assembly campaigns and the roadmap toward full detector integration are also discussed.
