The CMS Phase-II Tracker Upgrade — •Thomas Eichhorn — Deutsches Elektronen-Synchrotron DESY

From 2023 onward the Large Hadron Collider (LHC) at CERN will be upgraded to a new, so-called High-Luminosity LHC (HL-LHC). With this upgrade, the instantaneous luminosity will be increased to up to 7.5 × 10³⁴ cm²s⁻¹. After 10 years of operation, the CMS experiment will have accumulated an integrated luminosity of over 3000 fb⁻¹. These unprecedented luminosities have enormous consequences for the LHC and its experiments, such as CMS, and here especially for the innermost detector component, the tracking detector. To address the anticipated vast increase in particle density and the unprecedented radiation damage, a complete redesign of the CMS Tracker is needed. This talk will explain the forseen upgrade of the CMS Tracker, its components and some of the technological choices. Ongoing R&D efforts will also be highlighted.
