/Tracker Group
The high luminosity upgrade of the Large Hadron Collider, foreseen for 2026, necessitates the replacement of the CMS experiment’s silicon tracker. The innermost layer of the new pixel detector will be exposed to severe radiation, corresponding to a 1 MeV neutron equivalent fluence of up to $\Phi _{eq} = 2 \times 10^{16}$ cm$^{-2}$ , and an ionising dose of ${\approx } 5$ MGy after an integrated luminosity of 3000 fb$^{-1}$ .

/CMS
The upgrade of the LHC to the High-Luminosity LHC (HL-LHC) is expected to increase the LHC design luminosity by an order of magnitude. This will require silicon tracking detectors with a significantly higher radiation hardness. [...]

A new pixel detector for the CMS experiment is being built, owing to the instantaneous luminosities anticipated for the Phase I Upgrade of the LHC. The new CMS pixel detector provides four-hit tracking while featuring a reduced material budget as well as new cooling and powering schemes. [...]

/CMS Tracker Group
The degradation of signal in silicon sensors is studied under conditions expected at the CERN High-Luminosity LHC. 200 $\mu$m thick n-type silicon sensors are irradiated with protons of different energies to fluences of up to $3 \cdot 10^{15}$ neq/cm$^2$. [...]

LHC Collimation System Hardware Commissioning
/ Weiler, Th ; Aberle, O ; Assmann, Ralph Wolfgang ; Chamizo, R ; Kadi, Y ; Lettry, Jacques ; Losito, R ; Redaelli, S
The stored energy and intensity of the LHC beam exceed the damage level of the machine and the quench level of the magnets by far. Therefore a robust and reliable collimation system is required which prevents the quenching of the magnets during regular operation and protects the accelerator components from damage in the event of beam loss.
