Measurement of the fractional radiation length of a pixel module for the CMS Phase-2 upgrade via the multiple scattering of positrons / Tracker Group of the CMS Collaboration
High-luminosity particle collider experiments such as the ones planned at the High-Luminosity Large Hadron Collider require ever-greater vertexing precision of the tracking detectors, necessitating also reductions in the material budget of the detectors. Traditionally, the fractional radiation length ($x/X_0$) of detectors is either estimated using known properties of the constituent materials, or measured in dedicated runs of the final detector.

Beam Test Performance Studies of CMS Phase-2 Outer Tracker Module Prototypes / Tracker Group of the CMS Collaboration
A new tracking detector will be installed as part of the Phase-2 upgrade of the CMS detector for the high-luminosity LHC era. This tracking detector includes the Inner Tracker, equipped with silicon pixel sensor modules, and the Outer Tracker, consisting of modules with two parallel stacked silicon sensors. [...]

Evaluation of planar silicon pixel sensors with the RD53A readout chip for the Phase-2 Upgrade of the CMS Inner Tracker / CMS Collaboration
The Large Hadron Collider (LHC) at CERN will undergo an upgrade in order to increase its luminosity to $7.5 \times 10^{34}$ cm$^{-2}$s$^{-1}$. The increased luminosity during this High-Luminosity running phase\\ (HL-LHC), starting around 2029, means a higher rate of proton-proton interactions, hence a larger ionizing dose and particle fluence for the detectors. The current tracking system of the CMS experiment will be fully replaced in order to cope with the new operating conditions. [...]

CIC: a radiation tolerant 65 nm data aggregation ASIC for the future CMS tracking detector at LHC / Nodari, B (IP2I, Lyon) ; Bergamin, G (CERN) ; Caponetto, L (IP2I, Lyon) ; Caratelli, A (CERN) ; Ceresa, D (CERN) ; Galbit, G (IP2I, Lyon) ; Kloukinas, K (CERN) ; Scarfi’, S (CERN) ; Viret, S (IP2I, Lyon)
For the Phase II upgrade at HL-LHC, CMS needs a new Outer Tracker detector able to cope with reduced material budget, increased radiation tolerance and higher pile-up conditions with respect to LHC. The main feature of the Outer Tracker will be its inclusion at the first level of the CMS trigger system with data readout at 40 MHz. [...]

Evaluation of HPK $n^+$-$p$ planar pixel sensors for the CMS Phase-2 upgrade / Tracker Group of the CMS Collaboration
To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determined by the long operation time of 10~years with an instantaneous peak luminosity of up to $7.5\times 10^{34}$~cm$^{-2}$s$^{-1}$ in the ultimate performance scenario. Depending on the radial distance from the interaction point, the silicon sensors will receive a particle fluence corresponding to a non-ionizing energy loss of up to $\Phi_{\text{eq}} = 3.5\times 10^{16}$~cm$^{-2}$.

Test beam performance of a CBC3-based mini-module for the Phase-2 CMS Outer Tracker before and after neutron irradiation / Tracker Group of the CMS Collaboration
The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5-7.5$\times10^{34}$ cm$^{-2}$s$^{-1}$. This High Luminosity upgrade of the LHC (HL-LHC) will deliver a total of 3000-4000 fb$^{-1}$ of proton-proton collisions at a center-of-mass energy of 13-14 TeV. [...]

First results from the CIC data aggregation ASIC for the Phase 2 CMS Outer Tracker / CMS Tracker group Collaboration
The Concentrator Integrated Circuit (CIC) ASIC is a front-end chip for both Pixel-Strip (PS) and Strip-Strip (2S) modules of the future Phase 2 CMS Outer Tracker at the High-Luminosity LHC (HL-LHC). Prototyped in a 65 nm CMOS technology, the CIC aggregates the digital data coming from eight upstream front-end chips, formatting it into data packets containing the trigger information from eight bunch crossings and the raw data from events passing the Level 1 (L1) trigger, before transmission to the lpGBT.
