Novel method to assess the electromagnetic radiation damage using HGCAL silicon sensors / Fialova, E (CERN ; CTU, Prague) ; Defranchis, M M (CERN) ; Kopsalis, I (Athens U.) ; Peltola, T (Texas Tech.)
Studies of the silicon dioxide (SiO$_{2}$) passivation layer in n-on-p silicon sensors, which will be used in the CMS High Granularity Calorimeter (HGCAL), are important for improving their performance notonly at the High-Luminosity LHC, but also at future high-energy physics experiments.This work explores a novel method for estimating the effect of surface radiation damage on inter-pad isolation in HGCAL sensors by measuring the threshold voltage for inter-electrode isolation V$_{th,iso}$. Test diodes with different SiO$_{2}$ variants are irradiated with X-rays, and their characteristics are measured at a controlledtemperature of -20°C. [...]

The ATLAS ITk Pixel and Strip Detector System for the Phase-II LHC Upgrade / Kopsalis, Ioannis (National Technical Univ. of Athens (GR)) /ATLAS Collaboration
The inner detector of the present ATLAS experiment has been designed and developed to function in the environment of the present Large Hadron Collider (LHC). At the ATLAS Phase-II Upgrade, the particle densities and radiation levels will exceed current levels by a factor of ten. [...]

Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter / CMS HGCAL Collaboration
A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transverse and longitudinal granularity. [...]

Specifications and Pre-Production of n+-in-p Large-format Strip Sensors fabricated in 6-inch Silicon Wafers, ATLAS18, for Inner Tracker of ATLAS Detector for High-Luminosity Large Hadron Collider / ATLAS Collaboration
The full volume of the inner tracker of the ATLAS experiment will be replaced with new all-Silicon detectors for HL-LHC. The strip detectors, in the radial extent of 40 to 100 cm, are made of four layers of cylindrical-structures in the barrel and six layers of disk-structures in the endcap section with 2 layers of strip sensors for stereo-viewing in each layer-structure.

Experimental Study and Empirical Modelling of Long Term Annealing of the ATLAS18 Sensors / ATLAS Collaboration
In order to continue the program of the LHC, the accelerator will be upgraded to the HL-LHC, which will have a design luminosity 10e3 cm^2 s^-1, an order of magnitude greater than the present machine. In order to meet the occupancy and radiation hardness requirements resulting from this increase in luminosity, the present ATLAS tracking detector must be replaced. [...]

Evaluation of MOS and Gated Diode Devices of the ATLAS ITk Test Chip / ATLAS Collaboration
The new ATLAS Inner Tracker (ITk) sub-detector is necessitated by the impending High Luminosity Large Hadron Collider (HL-LHC) upgrade. This replacement is part of the phase-II upgrade programme for the HL-LHC which will see a sevenfold increase in peak instantaneous luminosity with a total ionizing dose of 53 MRad. [...]
