/ Bilko, Kacper (CERN ; Lab. Hubert Curien, St. Etienne) ; García Alía, Rubén (CERN) ; Costantino, Alessandra (ESTEC, Noordwijk) ; Coronetti, Andrea (CERN) ; Danzeca, Salvatore (CERN) ; Delrieux, Marc (CERN) ; Emriskova, Natalia (CERN) ; Fraser, Matthew Alexander (CERN) ; Girard, Sylvain (Lab. Hubert Curien, St. Etienne ; IUF, Paris) ; Johnson, Eliott Philippe (CERN) et al.
We present the progress related to CERN’s capacity of delivering highly penetrating, high-linear energy transfer (LET) heavy ions for radiation effect testing of electronic components within the CHARM High-energy Ions for Micro Electronics Reliability Assurance (CHIMERA) project. Profiting from the existing accelerator infrastructure, Monte Carlo simulations, and a 300- $\mu $ m-thick silicon diode, we highlight the beam characterization capabilities and a summary of the beam properties.

Beam coupling impedance of the main extraction kickers in the CERN PS
/ Neroni, M (CERN ; U. Rome La Sapienza (main)) ; Barnes, M J (CERN) ; Lasheen, A (CERN) ; Mostacci, A (U. Rome La Sapienza (main)) ; Popovic, B (Argonne) ; Vollinger, C (CERN)
In view of the High Luminosity (HL) upgrade of the LHC, thebeam intensity must be doubled in the injector chain. To performreliable beam dynamics simulations, the beam coupling impedance inthe injectors, such as the Proton Synchrotron (PS), must be followedclosely by including all contributing elements into the impedancemodel.

High voltage consolidation of the temperature measurement channels of the LHC superconducting current leads
/ Trikoupis, N (CERN) ; Casas-Cubillos, J (CERN) ; Bustamante, E (CERN)
Recurrent dielectric breakdowns on the cryogenics instrumentation during the CERN LHC Electrical Quality Assurance (ELQA) campaigns led to an investigation of their root causes. During the CERN Long Shutdown 2 (LS2), several weaknesses were identified like floating wires or cable screens, cabling non-conformities, connector assembly issues, and weakness of the electronic conditioning cards.

Enhancement of System Observability During System-Level Radiation Testing Through Total Current Consumption Monitoring
/ Slipukhin, Ivan (CERN) ; Coronetti, Andrea (CERN) ; Alía, Rubén García (CERN) ; Saigné, Frédéric (IES, Montpellier) ; Boch, Jérôme (IES, Montpellier) ; Dilillo, Luigi (IES, Montpellier) ; Aguiar, Ygor Q (CERN) ; Cazzaniga, Carlo ; Kastriotou, Maria ; Dodd, Torran
System-level testing of electronics is an affordable method of assessment of the performance of complete electronic systems designed for applications in the radiation environment. Compared to component-level testing, system-level test offers a much smaller degree of observability about the performance of particular system elements. [...]

Overview of beam intensity issues and mitigations in the CERN-SPS fast wire scanners
/ Veness, Raymond (CERN) ; Guerrero, Ana (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Harrison, Anthony (CERN) ; Salvant, Benoit (CERN) ; Zannini, Carlo (CERN) ; Antuono, Chiara (CERN) ; Vollinger, Christine (CERN) ; de la Fuente, Elena (CERN) ; Carra, Federico (CERN) et al.
A new design of fast wire scanner was installed in the CERN injector complex as part of the upgrades linked to the High-Luminosity LHC Project. Initial operations with these beams were good, but during the planned intensity ramp-up one early 2023, all four SPS scanners failed at the same time. [...]

Status of Beam Instrumentation at the Electron Beam Test Stand at CERN

An electron beam test stand has been designed and constructed at CERN as part of the High Luminosity LHC (HL-LHC) project, in collaboration with the ARIES project, to test components related to the Hollow Electron Lens (HL-LHC) and the GSI Space Charge Compensation Electron Lens (ARIES). This comprehensive test facility incorporates normal conducting solenoid magnets, including horizontal and vertical correctors, which generate fields of fractional Tesla magnitude. [...]

Impedance reduction of the beam gas ionization monitors for the CERN SPS
/ Bursali, Hikmet (CERN) ; Andreazza, William (CERN) ; Khatri, Ghanshyambhai (CERN) ; Ramos Garcia, Maria Teresa (CERN) ; Storey, James (CERN) ; Vollenberg, Wil (CERN) ; Vollinger, Christine (CERN)
The beam gas ionization monitors (BGIs) are non-destructive instruments to measure the transverse beam profiles. With the goal to double the beam intensity in the injector chain for the High-Luminosity Large Hadron Collider (HL-LHC), any element contributing to the overall beam coupling impedance requires an in-depth impedance evaluation from the design stage.

Radiation levels from a beam gas curtain instrument at the LHC at CERN
/ Prelipcean, Daniel (CERN) ; Sequeiro, Cristina (CERN) ; Schneider, Gerhard (CERN) ; Lerner, Giuseppe (CERN) ; Ady, Marton (CERN) ; Sedlacek, Ondrej (CERN) ; Veness, Raymond (CERN) ; Garcia Alia, Ruben (CERN)
A prototype Beam Gas Curtain (BGC) monitor was installed at the Large Hadron Collider (LHC) at CERN to provide 2D images of the transverse beam profile during the ongoing Run 3 (2022 to date) and in view of the High Luminosity LHC upgrade (HL-LHC). By design, the BGC operation generates collisions between the beam particles and an injected gas jet proportionally to the beam intensity and the gas density, possibly causing radiation-induced issues to the downstream LHC equipment.
