Pixel detector for CMS upgrade / Orfanelli, Stella (CERN) /CMS Collaboration
The LHC machine upgrade program will increase the instantaneous luminosity delivered to the multi-purpose experiments up to 7.5x$10^{34}$\,cm$^{-2}$s$^{-1}$ in 2026, with the goal of an integrated luminosity of 3000\,fb$^{-1}$ by the end of 2037. In order to fully exploit this luminosity, CMS plans to build a completely new pixel detector. [...]

The CMS Phase-1 pixel detector -- experience and lessons learned from two years of operation / Vormwald, Benedikt Roland (Hamburg U.) /CMS Collaboration
In 2017, CMS has installed a new pixel detector with 124M channels that features full 4-hit coverage in the tracking volume ($\eta<2.5$) and is capable to withstand instantaneous luminosities of $2\cdot10^{34}\,\mathrm{cm}^{-2}\mathrm{s}^{-1}$ and beyond. By now the detector has been successfully operated for two years in proton and heavy ion collisions. [...]

Results and prospects with the CMS-TOTEM Precision Proton Spectrometer / Vilela Pereira, Antonio (Rio de Janeiro State U.) /CMS and TOTEM Collaborations
The PPS (Precision Proton Spectrometer) detector system consists of silicon tracking stations as well as timing detectors to measure both the position and direction of protons and their time-of-flight with high precision. They are located at around 200--220~m from the interaction point in the very forward region on both sides of the CMS experiment. [...]

The Upgrade of the CMS Inner Tracker for HL-LHC / Backhaus, Malte (Zurich, ETH) /CMS Collaboration
During the Long Shutdown (LS) from 2024 to 2026 the Large Hadron Collider (LHC) will be upgraded in order to provide a ten-fold increase of the data rate to the experiments. This will enhance the sensitivity of the experiments to possible unexplored rare processes and to allow for precision measurements of known processes, in particular of the properties of the Higgs Boson which was discovered in 2012.

Serial powering and high hit rate efficiency measurement for the Phase 2 Upgrade of the CMS Pixel Detector. / Ruini, Daniele (Zurich, ETH)
A serially powered pixel detector is the baseline choice for the High Luminosity upgrade of the inner tracker of the CMS experiment. A serial power distribution scheme, compared to parallel powering, requires less cable mass, offers higher power efficiency and is less susceptible to voltage transients. [...]

First Results on 3D Pixel Sensors Interconnected to the RD53A Readout Chip after Irradiation to $1\times$$10^{16}$\,neq cm$^{-2}$ / Meschini, Marco (INFN, Florence) ; Ceccarelli, Rudy (INFN, Florence) ; Dinardo, Mauro (INFN, Milan Bicocca ; Milan Bicocca U.) ; Gennai, Simone (INFN, Milan Bicocca) ; Moroni, Luigi (INFN, Milan Bicocca) ; Zuolo, Davide (INFN, Milan Bicocca ; Milan Bicocca U.) ; Demaria, L ; Monteil, Ennio (INFN, Turin ; Turin U.) ; Gaioni, Luigi (INFN, Pavia) ; Messineo, Alberto (INFN, Pisa ; Pisa U.) et al.
Results obtained with 3D columnar pixel sensors bump-bonded to the RD53A prototype readout chip are reported. The interconnected modules have been tested in a hadron beam before and after irradiation to a fluence of about $1\times$$10^{16}$\,neq cm$^{-2}$ (1\,MeV equivalent neutrons). All presented results are part of the CMS R\&D; activities in view of the pixel detector upgrade for the High Luminosity phase of the LHC at CERN (HL-LHC). [...]
