In the scope of the High Luminosity program of the Large Hadron Collider at CERN, the ATLAS and CMS experiments are advancing the preparation for the production, commissioning and installation of their new environment-friendly low-temperature detector cooling systems for their new trackers, calorimeters and timing layers. The selected secondary ¿on-detector¿ CO₂ pumped loop concept is the evolution of the successful 2PACL technique allowing for oil-free, stable, low-temperature control. [...]

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. [...]

The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3 / ATLAS Collaboration
The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of $\mathcal{L}=2\times 10^{34}\mathrm{cm}^{-2}\mathrm{s}^{-1}$ was routinely achieved at the start of fills, twice the design luminosity. [...]

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. [...]

Manufacturing technologies and joining methods of metallic thin-walled pipes for use in high pressure cooling systems / McNair, Sophie A M (Bath U.) ; Chaharsooghi, Alborz Shokrani (Bath U.) ; Carnevale, Mauro (Bath U.) ; Rhead, Andrew (Bath U.) ; Onnela, Antti (CERN) ; Daguin, Jerome (CERN) ; Cichy, Kamil (CERN) ; Postema, Hans (Cornell U.) ; Bacchetta, Nicola (CERN) ; French, Thomas (CERN) et al.
Small diameter thin-walled pipes, typically with a diameter less than 20 mm and a ratio of outer diameter to wall thickness is 20 or above, have increasingly become a key value adding factor for a number of industries including medical applications, electronics and chemical industries. In high-energy physics experiments, thin-walled pipes are needed in tracking detector cooling systems where the mass of all components needs to be minimised for physics measurement reasons. [...]

The fluid properties of CO$_2$ make it an ideal medium for the cooling of tracking detectors in experiments at particle accelerators. Detectors such as the Compact Muon Solenoid Outer Tracker at CERN will be cooled to a nominal temperature of -35 °C with CO$_2$ cooling to ensure the longevity of the silicon sensors. [...]
