Status and progress on the CMS Phase-II detector upgrades

ABSTRACT

The CMS experiment has an ambitious Phase-II upgrade plan, which includes nearly all parts of the detector. Key aspects include increased channel count and associated bandwidth, improved radiation hardness, and the addition of precision timing. An overview of the upgrade along with a discussion on the current status and recent progress is presented. Overall, excellent progress has been made in the past year, although some delays due to the Covid-19 pandemic were inevitable. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
