The CMS Tracker Upgrades – Pushing the Limits — •Benedikt Vormwald — Institute of Experimental Physics, Luruper Chaussee 149, 22761 Hamburg
During the extended year end technical stop 2016/2017 of the LHC, the CMS collaboration is installing a completely new pixel detector (Phase 1) as LHC is going to exceed the design luminosity of the old detector of 1034 cm−2s−1. The new detector will feature higher tracking efficiency and lower mass with four barrel layers and three forward/backward disks to provide a 4-hit coverage up to absolute pseudo-rapidities of 2.5.
For the high luminosity phase of the LHC starting around 2026, CMS will replace the entire silicon tracking system by new silicon strip and pixel detectors (Phase 2). The upgraded systems need to be able to cope with an instantaneous luminosity of up to 7× 1034 cm−2s−1 for a total of 3000 fb−1 in order to maintain the physics reach. Intense R&D activities are ongoing in order to define the final design of both subsystems.
In this talk, I will present the features and installation status of the Phase-1 pixel detector and discuss current developments and novel technologies and concepts of the Phase-2 tracker upgrade.
