The CELESTA CubeSat In-Flight Radiation Measurements and Their Comparison With Ground Facilities Predictions
/ Coronetti, Andrea (CERN) ; Zimmaro, Alessandro (CERN) ; Alía, Rubén García (CERN) ; Danzeca, Salvatore (CERN) ; Masi, Alessandro (CERN) ; Slipukhin, Ivan (CERN) ; Amodio, Alessio (CERN) ; Dijks, Jasper (CERN) ; Peronnard, Paul (CERN) ; Secondo, Raffaello (CERN) et al.
The CELESTA CubeSat has employed radiation monitors developed by the Conseil Européen pour la Recherche Nucléaire (CERN) Centre, used for measuring the radiation environment at accelerators, to measure the space radiation field in a medium-Earth orbit (MEO). The technology is based on three static random-access memories (SRAMs) that are sensitive to single-event upsets (SEUs) and single-event latchups (SELs). [...]

Development of a second-generation system for the reliable distribution of machine protection parameters
/ Bolton, Samuel (CERN) ; Blaszkiewicz, Milosz (CERN) ; Colinet, Antoine (CERN) ; Felsberger, Lukas (CERN) ; Guasch-Martinez, Josep (CERN) ; Martin, Christophe (CERN) ; Romera, Iván (CERN) ; Secondo, Raffaello (CERN) ; Uythoven, Jan (CERN)
The Safe Machine Parameter (SMP) system is an electronic hardware-based system which has been an integral part of the LHC’s machine protection strategy since it started operation. Its primary objective is to provide several parameters and interlock signals to critical machine protection users across the LHC and SPS accelerators, whilst prioritizing high reliability and availability.

The Safe Machine Parameter system (SMP) is a critical part of the machine protection system in CERN’s Large Hadron Collider (LHC) and the Super Proton Synchrotron (SPS). It broadcasts safety-critical parameters like beam energy, beam intensity, the beta functions and flags indicating safety levels of the beam to other machine protection elements. [...]

The Consolidation of the CERN Beam Interlock System
/ Johnson, Roland (CERN) ; Martin, Christophe (CERN) ; Podzorny, Tomasz (CERN) ; Romera, Iván (CERN) ; Secondo, Raffaello (CERN) ; Uythoven, Jan (CERN)
The Beam Interlock System (BIS) is a machine protection system that provides essential interlock control throughout the CERN accelerator complex. The current BIS has been in service since 2006; as such, it is approaching the end of its operational lifetime, with most components being obsolete. [...]

Interlock System Upgrades at the CERN Accelerator Complex During Long Shutdown 2
/ Uythoven, Jan (CERN) ; Antoine, Alain (CERN) ; Martin, Christophe (CERN) ; Mirana Fontan, Adrian (CERN) ; Mompo, Richard (CERN) ; Romera Ramírez, Iván (CERN) ; Secondo, Raffaello (CERN)
The CERN accelerator complex stopped operation at the end of 2018 for the Long Shutdown 2 (LS2), allowing for the LHC Injector Upgrade program (LIU) and consolidation work to be accomplished. A gradual restart of the different accelerators is ongoing in 2021, culminating with the LHC foreseen to be back in operation early 2022. [...]

Evaluation of an SFP Based Test Loop for a Future Upgrade of the Optical Transmission for CERN’s Beam Interlock System
/ Secondo, Raffaello (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Martin, Christophe (CERN) ; Romera, Iván (CERN) ; Siemko, Andrzej (CERN) ; Uythoven, Jan (CERN)
The Beam Interlock System (BIS) is the backbone of CERN’s machine protection system. The BIS is responsible for relaying the so-called Beam Permit signal, initiating in case of need the controlled removal of the beam by the LHC Beam Dumping System. [...]

Machine protection experience from beam tests with crab cavity prototypes in the CERN SPS
/ Lindstrom, Bjorn (CERN ; Uppsala U. (main)) ; Bartosik, Hannes (CERN) ; Bohl, Thomas (CERN) ; Butterworth, Andrew (CERN) ; Calaga, Rama (CERN) ; Carver, Lee (CERN ; U. Liverpool (main)) ; Kain, Verena (CERN) ; Levens, Thomas (CERN) ; Papotti, Giulia (CERN) ; Secondo, Raffaello (CERN) et al.
Crab cavities (CCs) constitute a key component of the High Luminosity LHC (HL-LHC) project. In case of a failure, they can induce significant transverse beam offsets within tens of microseconds, necessitating a fast removal of the circulating beam to avoid damage to accelerator components due to losses from the displaced beam halo.

Single event effects in high-energy accelerators
/ García Alía, Rubén (CERN) ; Brugger, Markus (CERN) ; Danzeca, Salvatore (CERN) ; Cerutti, Francesco (CERN) ; de Carvalho Saraiva, Joao Pedro (CERN) ; Denz, Reiner (CERN) ; Ferrari, Alfredo (CERN) ; Foro, Lionel L (CERN) ; Peronnard, Paul (CERN) ; Røed, Ketil (U. Oslo (main)) et al.
The radiation environment encountered at high-energy hadron accelerators strongly differs from the environment relevant for space applications. The mixed-field expected at modern accelerators is composed of charged and neutral hadrons (protons, pions, kaons and neutrons), photons, electrons, positrons and muons, ranging from very low (thermal) energies up to the TeV range.

Analysis of SEL on Commercial SRAM Memories and Mixed-Field Characterization of a Latchup Detection Circuit For LEO Space Applications
/ Secondo, Raffaello (CERN ; IES, Montpellier) ; Alía, Ruben (CERN) ; Peronnard, Paul (CERN) ; Brugger, Markus (CERN) ; Masi, Alessandro (CERN) ; Danzeca, Salvatore (CERN) ; Merlenghi, Anne-Sophie (CERN) ; Vaillé, Jean-Roch (IES, Montpellier ; U. Nîmes, Nîmes) ; Dusseau, Laurent (IES, Montpellier)
A single event latchup (SEL) experiment based on commercial static random access memory (SRAM) memories has recently been proposed in the framework of the European Organization for Nuclear Research (CERN) Latchup Experiment and Student Satellite nanosatellite low Earth orbit (LEO) space mission. SEL characterization of three commercial SRAM memories has been carried out at the Paul Scherrer Institut (PSI) facility, using monoenergetic focused proton beams and different acquisition setups.
