The CMS Phase-1 Pixel Detector


The original CMS pixel detector has been replaced with an upgraded pixel system in the LHC winter shutdown 2016/2017. The design of the upgraded CMS pixel detector allows to cope with the higher instantaneaous luminosities that have been achieved by the LHC after the first long shutdown of the accelerator. The new upgraded detector has higher tracking efficiency and lower mass with four barrel layers and three forward/backward disks to provide a hit coverage up to absolute pseudorapidities of 2.5. This paper describes the design and construction of the CMS Phase-1 pixel detector as well as its performance during collision data-taking.
