U., Dortmund) et al.
In high-energy physics, there is a need to investigate silicon sensor concepts that offer large-area coverage and cost-efficiency for particle tracking detectors. Sensors based on CMOS imaging technology present a promising alternative silicon sensor concept. [...]

Characterization of the FBK-LGAD devices manufactured at an external foundry for large-volume productions
/ CMS Collaboration
In recent years, the HEP detector community has shown an increasing interest in Low Gain Avalanche Diodes (LGADs) due to their excellent temporal resolution, good radiation resistance, and low material budget. An example of this is the upcoming CMS Endcap Timing Layer (ETL), a subdetector which will feature four disks (14 m$^{2}$) covered with these devices.In this context, Fondazione Bruno Kessler (FBK), one of the qualified producers of the ETL LGAD sensors, has recently initiated a technology transfer of the FBK-LGAD technology to an external CMOS foundry (LFoundry) in order to enable a larger and cost-effective production.The first prototype run from LFoundry was produced in May 2024.

State-of-the-art Nb3Sn superconducting accelerator magnets are still prone to lengthy training. This study investigates whether direct heat from fractures in commonly used magnet impregnant is sufficient to cause the instabilities during training. [...]

/ALICE Collaboration
As part of the upgrade to the Inner Tracking System 3 (ITS3) for ALICE and the strategicR&D; programme of the CERN EP department, stitched Monolithic Active Pixel Sensors (MAPS) arebeing developed using a 65 nm CMOS imaging process. Several sensor prototypes were characterizedin laboratory using radioactive sources, particularly the $^{55}$Fe source, which was extensivelyused. [...]

Study of the UHV compatibility of selected ferritic stainless steels for application in vacuum systems of future gravitational wave detectors
/ Scarcia, Carlo (CERN) ; Bregliozzi, Giuseppe (CERN) ; Chiggiato, Paolo (CERN) ; Wevers, Ivo (CERN)
Future gravitational wave detectors (GWDs), such as the Cosmic Explorer and the Einstein Telescope, demand extensive ultrahigh vacuum (UHV) systems, making material cost and performance critical considerations. This study explores the potential of ferritic stainless steel, specifically AISI 441 and AISI 444, as a cost-effective alternative to the commonly used austenitic stainless steel for UHV components, focusing on the analysis of outgassing rates pre- and postbakeout at 80 and 150°C for 48 h.

Dielectric, thermal and mechanical properties of insulation systems for quench heaters for the protection of superconducting magnets
/ Scheuerlein, Christian (CERN) ; Osuna, Javier (CERN) ; Vielhauer, Julia (CERN) ; De Oliveira, Rui (CERN) ; Koettig, Torsten (CERN) ; Piccin, Roland (CERN)
High dielectric strength, low thermal resistance and mechanical robustness are conflicting requirements on the insulation system between the superconductors in magnet coils and the quench heaters placed on the coil for active protection in case of a quench. To investigate possibilities to further improve the performance of quench heaters for future superconducting magnets, we have characterised polyimide, PEEK and fibre reinforced PEEK films that can be used to produce large flexibly quench heater circuits.

Advanced Composite Insulation Systems in Nb$_{3}$Sn Superconducting Magnets for Accelerators: Electrical Characterization of Laminates at Cryogenic Temperatures
/ Osuna, J (CERN) ; Piccin, R (CERN) ; Pincot, F O (CERN) ; Polvani, D (CERN ; Bologna U.) ; Scheuerlein, C (CERN)
The electrical insulation system in wind-and-react Nb3Sn superconducting magnets must be robust, such that it can sustain the mechanical stresses, high radiation doses, and thermal cycles involved in the operation of the magnets. The chosen cable insulation material, currently a thin layer of braided S2 Glass, must also withstand a high-temperature heat treatment in an inert atmosphere, required to develop the superconducting phase in the cable.
