Neutron-induced cross section measurements / Massimi, C ; Aberle, O (CERN) ; Alcayne, V ; Altieri, S ; Amaducci, S ; Andrzejewski, J ; Babiano-Suarez, V ; Bacak, M (CERN) ; Balibrea, J ; Beltrami, C et al.
Neutron-induced cross sections represent the main nuclear input to models of stellar and Big-Bang nucleosynthesis. While (n,γ) reactions are relevant for the formation of elements heavier than iron, (n,p) and (n,α) reactions can play an important role in specific cases. [...]

This paper provides an extensive overview of more than a decade of continuous data collected by the Fiber Optic Sensing for CMS (FOS4CMS) network, featuring over 1000 Fiber Bragg Grating (FBG) sensors. These FBG sensors have been instrumental in monitoring temperature and strain within the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). [...]

Monolithic active pixel sensors based on the TPSCo 65 nm imaging CMOS technology: an overview of results and future challenges / Ripamonti, Giacomo (CERN)
Monolithic active pixel sensors (MAPS) are a key enabling technology for the next generation of detectors in High-Energy Physics experiments due to their low material budget, fine spatial resolution, and scalability to large areas at low cost. Building on the success of ALPIDE in the ALICE ITS2 detector, the CERN EP R&D; program in synergy with the ALICE experiment have adopted the TPSCo 65 nm imaging CMOS process to address the demands of future detectors.

The forward calorimeter of the ALICE experiment at CERN LHC / Simeonov, Radoslav (Sofia U. (main)) /ALICE Collaboration
A new forward calorimeter (FoCal), covering the pseudorapidity range 3.4 ≤ η ≤ 5.8, is proposed in order to extend the physics reach of ALICE during the LHC Run 4. The FoCal comprises a high-granularity electromagnetic calorimeter with silicon pixel and pad readout as well as a hadronic calorimeter. [...]

Recent testbeam studies of ATLAS ITk pixel modules / ATLAS Collaboration
The High-Luminosity Large Hadron Collider (HL-LHC) will deliver instantaneous luminosities up to five times higher than those of the current LHC, reaching an unprecedented $7.5 \times 10^{34} \text{cm}^{-2}\text{s}^{-1}$. This significant increase in luminosity — resulting in an average pileup of over 200 interactions per bunch crossing — will pose serious challenges to existing detector systems. [...]

OPTIMA, a board dedicated to Optimized Precision Timing for Multichannel Acquisition / De Benedetti, Federico (CERN ; Santiago de Compostela U.) ; Coco, Victor (CERN) ; Collins, Paula (CERN) ; Dumps, Raphael (CERN) ; Lemos Cid, Edgar (CERN) ; Gomez, Alfonso Puicercus (CERN ; U. Groningen, VSI) ; Rodriguez Rodriguez, Efren (CERN) ; Williams, Morag (CERN)
In the new era of HL-LHC experiments, fast-timing detectors are emerging as critical tools for background rejection. Typical requirements include a temporal hit resolution of about 50 ps, a spatial resolution of around 12 $μ$m, and radiation hardness up to $10^{17}$n$_\text{eq}$/cm$^2$. [...]
