The new Inner Tracker CMS pixel detector for the High-Lumi upgrade of LHC will be designed to sustain and collect till to 1 MeV neutron equivalent fluence ($\phi_{eq}$) of up to 2.3 x 10$^{16}$ cm$^{-2}$ for more than 3000 fb$^{-1}$ of integrated luminosity. Various solutions are being evaluated in terms of pixel pitch, sensor designs, and vendors.

After the current running period Run 3 the LHC will undergo a major upgrade with the instantaneous luminosity reaching at $7.5 \times 10^{34}$ $cm^{-2}$ $s^{-1}$. In order to maintain or improve the physics performance of the CMS detector in this challenging conditions of the HL-LHC, the entire tracking system must be replaced with new detectors with higher radiation tolerance and improved...
The quality of the silicon oxide layer in 8'' sensor prototypes for the CMS High Granularity Calorimeter (HGCAL) is studied by means of X-ray irradiation of dedicated test structures at the CERN ObeliX facility. A fully automated irradiation and measurement setup called AXIOM (Automated X-ray Irradiation and Oxide Measurements) has been developed at CERN for this purpose.
Different oxide...
The main goal of the presentation is to show the dependence of the leakage current and full depletion voltage on TID. Whereas the measured I-V characteristics show a linear dependence on TID, the full depletion voltage and thus also the effective doping concentration significantly decreases with higher gamma irradiation. The gradual decrease of the effective doping concentration with higher...
