The CMS pixel detector: ready for the future? — •Jory Sonneveld — Universität Hamburg, Hamburg, Germany

A new pixel detector has been installed in the heart of the Compact Muon Solenoid (CMS) early 2017 to meet the challenges of the high-pileup and high-luminosity environment from proton-proton collisions at the Large Hadron Collider (LHC). Despite many challenges, the pixel detector's performance was excellent. The innermost pixel layer, which has withstood radiation levels of 8e14 neq/cm2, is currently being replaced for the coming years of data taking.

For the future high luminosity LHC (HL-LHC), CMS will undergo a major upgrade to be able to fully exploit the increased luminosity and the entire tracker will be replaced. At the HL-LHC, the inner tracker will see hit rates up to 3.2 GHz/ cm2 and unprecedented levels of radiation up to 1.2 Grad and 2e16 neq/cm2. This is more than 20 times the fluence seen by the current CMS pixel detector up until today.

This presentation will discuss experience and lessons learned in operating the CMS phase 1 pixel detector, as well as new developments and test beam results from R&D for the phase 2 upgrade of the CMS pixel detector.
