Fab-to-fab and run-to-run variability in 130 nm and 65 nm CMOS technologies exposed to ultra-high TID / Termo, G (CERN ; Ecole Polytechnique, Lausanne) ; Borghello, G (CERN) ; Faccio, F (CERN) ; Michelis, S (CERN) ; Koukab, A (Ecole Polytechnique, Lausanne) ; Sallese, J M (Ecole Polytechnique, Lausanne)
The discovery of a large fab-to-fab variability in the TID response of the CMOS technologies used in the design of ASICs for the particle detectors of the HL-LHC triggered a monitoring effort to verify the consistency of the CMOS production process over time. As of 2014, 22 chips from 3 different fabs in 130 nm CMOS technology and 11 chips from 2 different fabs in 65 nm CMOS technology have been irradiated to ultra-high doses, ranging from 100 Mrad(SiO$_{2}$) to 1 Grad(SiO$_{2}$).

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. [...]

Radiation response of 28 nm CMOS transistors at high proton and neutron fluences for high energy physics applications / Termo, G (CERN ; LPHE, Lausanne) ; Borghello, G (CERN) ; Faccio, F (CERN) ; Michelis, S (CERN) ; Koukab, A (LPHE, Lausanne) ; Sallese, J M (LPHE, Lausanne)
The 28 nm CMOS technology was selected as a promising candidate to upgrade electronics of particle detectors at CERN. Despite the robustness of this node to ultra-high levels of total ionizing dose has been proven, the resilience to 10161MeVneq/cm2 fluences is still unknown. [...]

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. [...]

bPOL48V, a rad-hard 48V DC/DC Converter for Space and HEP Applications / Michelis, Stefano (CERN) ; Van Der Blij, Nils Hans (CERN) ; Ripamonti, Giacomo (CERN) ; Antoszczuk, Pablo Daniel (CERN)
A radiation-hard DC/DC converter has been developed at CERN, which tolerates a higher input voltage (up to 48 V) and provides a larger output power than existing solutions. It is called bPOL48V, and it employs a commercial Gallium Nitride power device and a CERN-developed control ASIC (GaN_Controller). [...]

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$^{-2}$. [...]
