In high-energy particle accelerators, circulating particle beams with high intensity interact electromagnetically with their surroundings (i.e., metallic vacuum chambers of various geometries). These electromagnetic interactions, which are typically described through the concept of beam-coupling impedance, can represent a serious issue in terms of stability of the particle beam and heating on the accelerator structures.

A Radiation-Tolerant 25.6-Gb/s High-Speed Transmitter in 28-nm CMOS With a Tolerance of 1 Grad / Klekotko, A (CERN ; Leuven U.) ; Biereigel, S (CERN) ; Baszczyk, M (CERN) ; Moreira, P (CERN) ; Martina, F (CERN) ; Prinzie, J (Leuven U.) ; Kulis, S (Leuven U.)
This article presents a 25.6-Gbit $\cdot $ s−1 high-speed transmitter (HST) manufactured using 28-nm CMOS technology. The HST macroblock includes an all-digital phase-locked loop (ADPLL), duty cycle corrector (DCC) circuit, data pattern generator, serializer, and a driver capable of driving the differential 100- $\Omega $ line as well as a silicon photonics (SiPh) ring modulator (RM).

Single-Event Effect Responses of CMOS Integrated Planar Multiturn Inductors in LC-Tank Oscillators Under Heavy-Ion Microbeam Irradiation / Adom-Bamfi, Gideon (Leuven U.) ; Biereigel, Stefan (CERN) ; Leroux, Paul (Leuven U.) ; Prinzie, Jeffrey (Leuven U.)
This article presents detailed measurements of a novel radiation effect caused by the sensitivity of on-chip spiral inductors to ionizing particles, leading to single-event frequency transients (SEFTs) in LC-tank oscillators. Quantitative experimental results from heavy-ion microbeam irradiation of two-turn and four-turn inductor samples are presented. [...]

Exploring Radiation-Induced Vulnerabilities in RFICs Through Traditional RF Metrics / Scialdone, Antonio (CERN ; LIRMM, Montpellier ; Montpellier U. ; CNRS, France) ; Ferraro, Rudy (cern) ; Dilillo, Luigi (LIRMM, Montpellier ; Montpellier U. ; CNRS, France) ; Saigne, Frederic (Montpellier U. ; CNRS, France) ; Boch, Jérôme (CNRS, France ; Montpellier U.) ; Masi, Alessandro (CERN) ; Danzeca, Salvatore (CERN)
This article describes how to analyze radiation-induced effects using traditional radio-frequency (RF) metrics in RF integrated circuits (RFICs) to be used in the implementation of software-defined radios (SDRs). The impacts of total ionizing dose (TID) and single-event effects (SEEs) on the device characteristics are shown and their consequences for an SDR are discussed. [...]

EMC concepts applied to the switching mode power converters supplying the superconductive magnets for the CERN LHC accelerator / Thurel, Yves (CERN) ; Bordy, Frédérick (CERN) ; Charoy, Alain (EMC Expert AEMC, Seyssins)
The LHC (Large Hadron Collider) particle accelerator makes extensive use of switching mode power supplies, in charge of delivering a high precision regulated output current to superconductive magnets controlling and driving the high energy beam of particles. Obtaining such level of precision was achieved through a given approach regarding the architecture of the converter, which was split into three fundamental elements. [...]

Some Compelling Overview of Charged Particle Multplicity Distribution in pp Collisions at the LHC / Aggarwal, Ritu (Pune U.) ; Kaur, Manjit (Panjab U.)
In this paper we report the oscillatory behavior observed in the modified combinants when Shifted-Gompertz distribution is used to define the phenomenology of the multi-particle production for the pp collisions. These oscillatory behavior in the modified combinants \(C_j\), were first reported using the modified NBD. [...]

Charge Buildup and Spatial Distribution of Interface Traps in 65-nm pMOSFETs Irradiated to Ultrahigh Doses / Bonaldo, Stefano (U. Padua (main)) ; Gerardin, Simone (U. Padua (main)) ; Jin, Xiaoming (Northwest Inst. Nucl. Tech., Xian) ; Paccagnella, Alessandro (U. Padua (main)) ; Faccio, Federico (CERN) ; Borghello, Giulio (CERN) ; Fleetwood, Daniel M (Vanderbilt U. (main))
In this paper, a commercial 65-nm CMOS technology is irradiated at ultrahigh ionizing doses and then annealed at high temperature under different bias conditions. The experimental results demonstrate the high sensitivity of pMOSFETs to radiation-induced short-channel effects, related to the buildup of defects in spacer dielectrics. [...]
