Comparison of High Energy X-Ray and Cobalt-60 Irradiations on MOS Capacitors
/ Girones, Vincent (Montpellier U.) ; Boch, Jérôme (Montpellier U.) ; Saigné, Frédéric (Montpellier U.) ; Carapelle, Alain (CERN) ; Chapon, Arnaud ; Maraine, Tadec (Montpellier U.) ; Alía, Rubén García (CERN)
The use of a high energy X-ray generator for Total Ionizing Dose (TID) testing is studied on metal-oxide semiconductor (MOS) capacitors. Several conditions were studied for the high energy X-ray irradiations (with aluminum and lead filters) and the experimental results are compared to Cobalt 60 (Co-60) irradiations. [...]

Radiation-Induced Charge Trapping in Shallow Trench Isolations of FinFETs
/ Bonaldo, Stefano (Padua U. ; INFN, Padua) ; Wallace, Trace (Arizona State U., Tempe) ; Barnaby, Hugh (Arizona State U., Tempe) ; Borghello, Giulio (CERN) ; Termo, Gennaro (CERN ; Ecole Polytechnique, Lausanne) ; Faccio, Federico (CERN) ; Fleetwood, Daniel M (Vanderbilt U.) ; Mattiazzo, Serena (Padua U. ; INFN, Padua) ; Bagatin, Marta (Padua U. ; INFN, Padua) ; Paccagnella, Alessandro (Padua U. ; INFN, Padua) et al.
We provide comprehensive experimental data and technology computer-aided design (TCAD) simulations to clarify total-ionizing-dose mechanisms in 16-nm Si FinFETs. In n-channel FinFETs irradiated to ultrahigh doses, the transconductance evolution rebounds (increase up to 3–10 Mrad followed by a decrease), while the drain-to-source leakage current steadily augments until reaching a plateau at very large doses. [...]

Radiation Environment in the Large Hadron Collider During the 2022 Restart and Related RHA Implications
/ Biłko, Kacper (CERN ; Lab. Hubert Curien, St. Etienne) ; García Alía, Rubén (CERN) ; Aguiar, Ygor (CERN) ; Danzeca, Salvatore (CERN) ; Di Francesca, Diego (CERN) ; Gilardoni, Simone (CERN) ; Girard, Sylvain (ICJ, Lyon ; IUF, Paris) ; Ricci, Daniel (CERN) ; Sebban, Marc (Lab. Hubert Curien, St. Etienne) ; Uznanski, Slawosz (CERN)
In this work, we present the radiation environment of the large hadron collider (LHC), focusing on the year 2022, the first after the Long Shutdown 2 (LS2) (2019–2021). We highlight the most prominent radiation-level changes with respect to the 2018 operation, commenting on the related Radiation Hardness Assurance implications. [...]

Advancements in TOF-PET using DOI Capable Modules and Low-Noise High-Frequency Readout
/ Terragni, G (CERN ; Vienna U.) ; Kratochwil, N (CERN) ; Lowis, C (CERN ; RWTH Aachen U.) ; Pagano, F (CERN ; INFN, Milan Bicocca) ; Cates, J W (LBNL, Berkeley) ; Pizzichemi, M (CERN ; INFN, Milan Bicocca) ; Marton, J (Vienna U.) ; Auffray Hillemanns, E (CERN)
Achieving good time resolution has become a prerequisite in positron emission tomography (PET) to improve the signal-to-noise ratio and thus the quality of the reconstructed image. A particularly attractive solution for the electronic readout is using low-noise high-frequency circuits (HF), which have demonstrated excellent timing performance in time-of-flight (TOF)-PET applications.

Particle physics experiments running at future accelerator facilities will rely on fast timing detectors to cope with high event pileup and to enhance particle identification capabilities. Direct band gap engineered semiconductor nanostructures show a high potential for emission of prompt photons due to quantum confinement, standing out in fast timing and high light yield with potential low cost production, thus triggering interest in the high energy physics community.

Fast28 a low-power fast readout design for SiPMs in 28nm CMOS
/ Piller, M (CERN ; Graz, Tech. U.) ; Ballabriga, R (CERN) ; Bandi, F (CERN) ; Campbell, M (CERN) ; Deutschmann, B (Graz, Tech. U.) ; Fernández-Tenllado, J M (CERN) ; Gascon, D (Barcelona U.) ; Gomez, S (Barcelona, Polytechnic U. ; Barcelona U.) ; Michalowska-Forsyth, A (Graz, Tech. U.) ; Mauricio, J (Barcelona U.) et al.
The field of detector readout electronics for precise timing has experienced a remarkable surge of interest due to its diverse range of applications in nuclear medicine such as Positron Emission Tomography (PET), High Energy Physics (HEP), Time-of-Flight (ToF) mass spectrometry and many other fields. This growth can be attributed to rapid advancements in photodetectors, particularly the silicon photomultiplier (SiPM), which has demonstrated exceptional suitability for these applications, owing to its ability to generate signals with unprecedentedly fast rise times.
