Total Ionizing Dose in Nano-Scaled CMOS Technologies / Faccio, Federico (CERN) ; Borghello, Giulio (CERN) ; Bonaldo, Stefano (U. Padua (main))
espite incredible technological advances in the fabrication of MOS transistors, the widespread use of isolation layers makes the total ionizing dose (TID) a persistent threat to the operation of these devices in ionizing radiation environments. This article provides a comprehensive review of the past three decades of research on the TID effects in transistors built across various scaled complementary metal-oxide-semiconductor (CMOS) nodes, ranging from a 1.6-μm planar MOS field-effect transistor (MOSFET) technology to FinFETs produced in a 16-nm node.

Beam-based impedance measurement of HL-LHC low-impedance collimators / Kurtulus, A (Zurich, ETH ; CERN) ; Amorim, D (CERN) ; Biancacci, N (CERN) ; Buffat, X (CERN) ; Giacomel, L (CERN) ; Leuthold, J (Zurich, ETH) ; Mounet, N (CERN) ; Redaelli, S (CERN) ; Smajic, J (Zurich, ETH)
The objective of the High Luminosity Large Hadron Collider (HL-LHC) upgrade is to attain an instantaneous luminosity that is 5 times greater than the design value of the LHC. This requires nearly 2 times higher beam intensity compared to the operational LHC value during Run 2 (2015–2018). [...]

Batch spacing optimization by reinforcement learning / Remta, Matthias (CERN) ; Velotti, Francesco (CERN) ; Rezagholi, Sharwin (Unlisted, AT)
Beams designated for the LHC are injected into the SPS in multiple batches. Given the tight spacing of 200 ns between these batches, the injection kickers have to be precisely synchronized with the injected beam to minimize injection oscillations. [...]

Monitoring of a high temperature superconducting magnet by means of distributed optical fiber sensing / Marcon, Leonardo (U. Padua (main) ; Unlisted, CH) ; Castaldo, Bernardo (CERN) ; Chiuchiolo, Antonella (CERN ; INFN, Salerno) ; Van Nugteren, Jeroen (CERN ; Unlisted, CH) ; Bajas, Hugues (CERN) ; Kirby, Glyn (CERN) ; Galtarossa, Andrea (U. Padua (main)) ; Bajko, Marta (CERN) ; Palmieri, Luca (U. Padua (main))
Distributed optical fiber sensor is a unique technology that offers unprecedented advantages and performance especially in those experimental fields where the environmental harshness limits the applicability of standard sensors. By measuring the faint light backscattered by the fiber in response to a well-tailored probing signal, distributed sensors allow mapping the variation of physical parameters along the fiber path with high spatial resolution.
